0. INTRODUCTION
===============
o This document provides information on various Doom and Doom II games, and
  compares the game-console versions to the original IBM-PC ("PC") editions.

o Apple Macintosh ("Mac") and other computer-based editions of the PC Doom
  games exist, however they are identical in most aspects to the PC games, and
  so are generally not addressed in this document.  Other editions of Doom not
  addressed here may be included in future updates.

o This document does not address the "Final Doom" games for the IBM-PC and Sony
  PlayStation.  A similar document comparing these games can be accessed at:
  http://m1.aol.com/ledmeister/fdoomcmp.htm

o In the game descriptions included in this document, "Pros" are notable
  features of the indicated game version, some of which may set it above other
  versions covered here; "Cons" are generally features that existed in the
  original IBM-PC game(s) but are missing from the indicated version, or may
  otherwise cause a version to be rated below other versions covered here;
  "Miscellaneous" notes cover those features which do not necessarily fall
  under the other categories.

  -----------------------------------------------------------------------------
  Notes: Not all monsters, items, etc., appear in all games at all difficulty
  levels.  Also, some items found on a given map during a single-player game
  may be absent from the same map during a multiplayer game, and vice versa.
  In Nintendo 64 Doom 64, the "Demon" monster is referred to as a "Bull Demon".
  In Sega 32X Doom, a BFG 9000 weapon is only available when using cheat codes.
  For more information, access: http://m1.aol.com/ledmeister/doomcode.htm

o All games referred to in this document also include (in alphabetical order):
  An Automap (which may be scrolled and/or zoomed in/out), barrels (explosive),
  corrosive floor areas (slime, lava, etc.), elevators/lifts, music between map
  levels, secret map levels, secret rooms, "tally screens" between map levels,
  teleporter pads, and variable lighting.

o In all Doom/Doom II games, a player character may walk, turn, run, "jump"
  (run across small gaps), and side-step/strafe, both in first-person mode and
  while the Automap is displayed.

o The following are limitations which apply to all console Doom/Doom II games:
  Some maps copied from the original PC game(s) are simplified, significantly
  altered, or ommited; A game can only be saved after successful completion of
  an Area (a player cannot save a game in the middle of playing a map level,
  and then have it restored later to the same position); When a "saved" game is
  restored, a player always restarts the mission from the map's entry point;
  Deathmatch games cannot include monsters; Some original PC objects and/or
  surface textures are missing; Some missing or mismatched PC-game sounds; In
  games played on "Nightmare" skill level, killed monsters do not re-spawn; No
  option to record and replay games/demos; Cannot import external map levels;
  Cannot import alternate graphics or sounds/music; No way to adjust graphics
  resolution; No equivalent for several PC Doom cheat codes; Cannot place
  numerical markings on the Automap.

o All Doom/Doom II games will experience speed fluctuations during gameplay.
  In general, overall game speed will slow down with an increase in sprites and
  textures displayed on the screen, and will speed up with a decrease in
  displayed sprites and textures.

o Each player in a multiplayer game requires a dedicated game system with its
  own display device, a separate copy of the appropriate game, and the ability
  to establish a connection to the other player's system.  (There are no
  commercially sold versions of Doom that support "split-screen" play.)  Of the
  console Doom games, only the Sony PlayStation, Atari Jaguar, Super Nintendo
  and Game Boy Advance games support (or supported) a multiplayer mode.  In
  each case, a game system must be connected to another fully-compatible system
  via one or more separately-sold devices.

o With the exception of Doom II for the Game Boy Advance, all game-console Doom
  games exclude some of the map levels found in the original PC games.  Because
  of this, the playing order of map levels in a console Doom game will differ
  from that of the comparable PC game.  (Also, some console versions have new
  hidden exits added to some map levels.)

o In all Doom games, monsters can turn and/or move in any one of at least 8
  lateral directions.  (Note however, that in some versions of the game
  monsters often appear to be walking backwards, or "crab-walking" sideways.
  This happens in the Super Nintendo and Sega 32X Doom games, where artwork is
  supplied only for the forward surfaces of monsters; No artwork is available
  to give monsters the appearance of turning or facing away from the player.)

o Most console-based Doom games allow cheat codes to be entered with an
  ordinary game controller.  Various codes may also be loaded into console Doom
  games with separately sold devices (such as a Game Genie or Game Shark) that
  plug into the consoles.

o Index General PC PSX Saturn N64 Jaguar 3DO SNES 32X GBA GBA 2 Tables Glossary

2. COMPUTER-BASED DOOM/DOOM II GAMES
====================================
o Various models and classes of IBM-PC 486 computers, and PC-compatible 486 and
  Pentium computers were used as test systems for the various PC Doom games
  described in this document (version 1.9 of PC Ultimate Doom and version 1.9
  of PC Doom II: Hell on Earth were tested, as well as various earlier versions
  of all PC Doom games).  For testing multiplayer games, these systems were
  connected to similar systems via various network and/or modem connections.

o Pros: In general, more features and options, and greater versatility than all
  console versions of Doom or Doom II.  2 players may play simultaneously via
  modem connection; Up to 4 may play via network connection.  On a modern PC,
  gameplay is somewhat faster and/or smoother than in most console Doom games.
  Ability to use and configure a variety of input devices (keyboard, mouse,
  joystick, etc.) for game play.  Supports 9 screen sizes, which also allows
  the first-person view to be expanded to fill the entire screen (an option
  otherwise only available in Doom 64).  Deathmatch games may include monsters.
  Doom II-based PC games allow more monster types than are available in any
  console-based Doom or Doom II game.  A game in progress may be saved at any
  point and restored later to the same point.  Saved games retain copious
  information (player location, health, weapon, ammo and armor status, live/
  dead status of all monsters on the map level, etc.).  Original Doom with
  Episode 1 is still available as shareware.  Thousands of external map levels
  are available for use with these games.  Built-in ability to record and play
  back single-player or multiplayer games.  Later PC Doom/Doom II game releases
  include extensive documentation and reference material with the software.
  Separate programs exist which allow players to create or edit new map levels,
  new artwork and/or new sounds for existing Doom games.  A variety of free
  third-party engines have been released which provide better graphics, better
  multiplayer support, and other new features.  Wide variety of built-in cheat
  codes.

o Cons: A user must have 2 separate games ("The Ultimate Doom: Thy Flesh
  Consumed" and "Doom II: Hell on Earth") to play most of the map levels found
  in the Sony PlayStation (PSX) or Sega Saturn Doom games.  Original Doom
  graphics on most PC platforms tend be of a lower quality than the graphics
  found in the Nintendo 64 (N64) Doom game "Doom 64".  Some rarely-encountered
  flaws exist in some versions of some PC Doom/Doom II games, including a
  program bug that creates nearly-intangible monsters, and a bug that can allow
  a player character to become trapped partially inside solid objects when
  reloading saved games.

o Miscellaneous: Games by id Software and GT Interactive.  Disk or CD format.
  Decent graphics resolution and quality; Very good in some hardware/software
  configurations.  The commercial edition of Doom (or "Doom 1") for the PC
  includes 27 map levels, divided into three 9-map Episodes.  A later release
  of the game, called "The Ultimate Doom: Thy Flesh Consumed" includes the
  original first three Episodes, and a newer fourth Episode containing 9 more
  map levels.  Doom II ("Doom 2: Hell on Earth") for the PC has 32 map levels
  built in, and adds new monsters and 1 new weapon not found in Doom 1 or
  Ultimate Doom.  None of the maps built into any PC Doom/Doom II game are
  found in Doom 64.  Occasionally, when a Pain Elemental monster (in Doom II)
  dies, the Lost Souls generated by its explosion may be flung through nearby
  walls, where they may become trapped (this has little effect on the game,
  since Lost Souls do not count towards a Kills score).

3. SONY PLAYSTATION DOOM
========================
o A Sony PlayStation, model SCPH-1001, equipped with one standard PlayStation
  controller (model SCPH-1080), was used as the test system for the Custom
  PlayStation Edition of Doom described in this document.  For testing
  multiplayer games, the system was connected to an identical system via the
  PlayStation Link cable (model SCPH-1040).

o Pros: Features most of the map levels (or equivalents) from the IBM-PC games
  "The Ultimate Doom" and "Doom II" (Doom 2: Hell on Earth).  Large variety of
  monster types (17).  2-player link ability, providing the largest selection
  of multiplayer map levels among all console versions.  The first-person view
  and status bar combination fills the entire display space on the TV/monitor
  screen.  Map level, skill level, health, armor, weapon and ammo information
  is translated to a password code which is given after successful completion
  of each map level (many other console Doom games cannot save such information
  externally).  The last password entered or generated on the password screen
  may be re-entered with a single button press (useful when, for example, a
  player is killed and wishes to restart the map level with a non-default
  status).  Extensive controller customizing is allowed (Fire button can swap
  functions with Speed button or Activate button, etc.).

o Cons: Although the basic layouts for the "Doom II" map levels tend to match
  the equivalent PC-game maps with decent accuracy, many of the PSX's "Ultimate
  Doom" map levels are re-edited or otherwise simplified, as are the comparable
  maps in the Saturn, Jaguar, 3DO, Sega 32X and GBA Doom 1 games.  Minor errors
  appear in a few map levels (secret room impossible to access, difficulty in
  picking up an item, etc.).  No crushing ceilings in the "Ultimate Doom" maps.
  From powering up the PlayStation, there is a relatively long wait (over a
  minute) before the player can actually start playing.  Game cannot make use
  of a memory card (sold separately).  Game does not save controller or sound
  configuration settings.  Some monster/enemy types from PC Doom II are missing
  from this version, including the Arch-Vile, "SS Officer", and the "Baphomet"/
  Boss entity.  Occasionally, objects in the foreground are partially overlaid
  by background wall or floor textures.  Weapons are cyclic-access only
  (although weapon choices may be cycled while the game is paused).  The status
  bar can only display the ammo level of the currently selected weapon (in PC
  and GBA Doom games, all ammo levels for all weapons can be displayed at all
  times).  All of the built-in cheat codes are rather long and complex (for
  example, an invincibility cheat code is 3 button-presses on the Jaguar, 5 on
  the PC, 10 on the PlayStation).  No "Gamma Correction" feature or equivalent.

o Miscellaneous: Port by id Software and Williams Entertainment, Inc.  CD
  format; 1 CD.  59 map levels, 8 of which are not found in PC Doom games.
  Good graphics resolution and quality.  Gameplay speed is adequate, but can be
  somewhat slower than a PC Doom/Doom II game played on a modern computer.
  Game information stored in a password code may be inaccurate (health, armor
  and ammo level numbers tend to be rounded).  Password encryption schemes may
  vary (Doom passwords generated by one PSX system may be rejected on other PSX
  systems).  Graphics, overall, tend to be darker here than in many other
  versions.  Features music tracks (and other background audio effects) not
  found in PC Doom games.  Features some new lighting effects.  Health potions
  and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1%
  in the PC games).  In PC Doom II, the two shotgun types are both represented
  as weapon 3 in the status bar; In PSX Doom, the 2 shotgun types are separated
  into weapons 3 and 4.  No "Nightmare" skill level.  Some Doom II monsters
  (Heavy Weapon Dude, Revenant, etc.) appear in the "Ultimate Doom" maps when
  playing at the highest skill level ("Ultra Violence").  Monster and weapon
  sounds tend to differ from the sounds used in the PC games.  In this game,
  "blurred" objects are translucent and faded, but otherwise maintain their
  normal colors and surface features (in the PC games, "blurred" objects, when
  visible, are a translucent gray, with a flat, flowing/scrambled surface).
  Another version of the Spectre appears in this game: the "Nightmare Spectre",
  which appears visibly darker, and is harder to kill than the normal Spectre.
  The Nightmare Spectre is a not a 1-to-1 replacement for the missing Arch-Vile
  monster.  Very tall rooms/areas from equivalent maps in the PC game(s) are
  shorter in this version.  An "X-ray vision" cheat code not found in the PC
  games is included.  An animated "wall of fire" exterior background is used in
  some map levels.  Some monsters and monster projectiles tend to move slower
  than their PC-game counterparts.  Graphics "noise" may sometimes be seen
  along the top or bottom edges of walls.  On occasion, the "marine face" in
  the status bar explodes when the player character dies.  On occasion, when a
  Pain Elemental monster dies, the Lost Souls generated by its explosion may be
  flung through nearby walls, where they may become trapped.  Lost Souls that
  are trapped in walls may still be visible, but may be impossible to kill
  (this has little effect on the game, since Lost Souls do not count towards a
  Kills score).  The voice effect that accompanies "victory text" is not heard
  if Music Volume is turned down.  Some monsters on the original PC maps are
  replaced with different monsters on the equivalent maps in this version.  In
  2-player games, both player characters wear a green uniform.  In Cooperative
  games, Frags are not indicated in the tally screens.  The "WOLFENSTEIN" and
  "GROSSE" secret map levels from PC Doom II do not appear in this game.  The
  "Commander Keen" character from PC Doom II is not included.  The "Lots of
  Goodies" cheat code will not add keys if they are not necessary.

  Notes: Map equivalency is based on general map layouts, not map names.
  The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
  "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
  The PSX "HELL KEEP" map does not match the PC "HELL KEEP" map.  (It does,
  however, match an equivalent map in the Saturn, Jaguar, 3DO and GBA Doom 1
  games.)

4. SEGA SATURN DOOM
===================
o A Sega Saturn unit, model MK-80000A, equipped with one standard Sega Saturn
  Control Pad (model MK-80116), was used as the test system for the Sega Saturn
  Doom game described in this document.

o Pros: Features most of the map levels (or equivalents) from the IBM-PC games
  "The Ultimate Doom" and "Doom II" (Doom 2: Hell on Earth).  Large variety of
  monster types (17).  The first-person view and status bar combination fills
  the entire display space on the TV/monitor screen.  Map level, skill level,
  health, armor, weapon and ammo information is translated to a password code
  which is given after successful completion of each map level (many other
  console Doom games cannot save such information externally).  The last
  password entered or generated on the password screen may be re-entered with a
  single button press (useful when, for example, a player is killed and wishes
  to restart the map level with a non-default status).  Extensive controller
  customizing is allowed (Fire button can swap functions with Speed button or
  Activate button, etc.).

o Cons: Overall game speed is slower/choppier in this version than in the PC
  games and some other console versions.  Although the basic layouts for the
  "Doom II" map levels tend to match the equivalent PC-game maps with decent
  accuracy, many of the Saturn's "Ultimate Doom" map levels are re-edited or
  otherwise simplified, as are the comparable maps in the PSX, Jaguar, 3DO,
  Sega 32X and GBA Doom 1 games.  Minor errors appear in a few map levels
  (secret room impossible to access, difficulty in picking up an item, etc.).
  No crushing ceilings in the "Ultimate Doom" maps.  Game cannot make use of a
  memory cartridge (sold separately).  Game does not save controller or sound
  configuration settings.  Basic "strafing"/side-stepping is somewhat slower
  here than in most other versions.  Weapons are cyclic-access only, and can
  only be cycled in one direction.  Some monster/enemy types from PC Doom II
  are missing from this version, including the Arch-Vile, "SS Officer", and the
  "Baphomet"/Boss entity.  The status bar can only display the ammo level of
  the currently selected weapon (in PC and GBA Doom games, all ammo levels for
  all weapons can be displayed at all times).  Background objects or surfaces
  occasionally "bleed through" or overlap foreground objects or surfaces.  No
  "Gamma Correction" feature or equivalent.

o Miscellaneous: Port by id Software, Rage Software and GT Interactive.  CD
  format; 1 CD.  59 map levels, 8 of which are not found in PC Doom games.
  Decent graphics resolution and quality.  Saturn Doom is very similar to the
  earlier PlayStation (PSX) Doom game (map levels, monsters, sound effects,
  music, and passwords used are all virtually identical).  Saturn Doom graphics
  are similar to PSX Doom graphics, but tend to be marginally brighter, and
  lack some of the enhanced lighting/color effects used in PSX Doom.  Game
  information stored in a password code may be inaccurate (health, armor and
  ammo level numbers tend to be rounded).  Health potions and Spiritual Armor
  bonuses add 2% to a player's health or armor (versus 1% in the PC games).  In
  PC Doom II, the two shotgun types are both represented as weapon 3 in the
  status bar; In Saturn Doom, the 2 shotgun types are separated into weapons 3
  and 4.  No "Nightmare" skill level.  Some Doom II monsters (Heavy Weapon
  Dude, Revenant, etc.) appear in the "Ultimate Doom" maps when playing at the
  highest skill level ("Ultra Violence").  Monster and weapon sounds tend to
  differ from the sounds used in the PC games.  In this game, "blurred" objects
  are translucent and faded, but otherwise maintain their normal colors and
  surface features (in the PC games, "blurred" objects, when visible, are a
  translucent gray, with a flat, flowing/scrambled surface).  A second version
  of the Spectre appears in this game: the "Nightmare Spectre", which looks
  like the normal Spectre, but is harder to kill.  The Nightmare Spectre is a
  not a 1-to-1 replacement for the missing Arch-Vile monster.  Very tall rooms/
  areas from equivalent maps in the PC game(s) are shorter in this version.
  Some monsters and monster projectiles tend to move slower than their PC-game
  counterparts.  The player character's basic running speed (compared to other
  moving objects in the same Doom environment) is somewhat faster here than in
  other versions.  In general, each weapon's "rapid-fire" rate is higher here
  than in other Doom games.  Graphics "noise" may sometimes be seen along the
  top or bottom edges of walls.  On occasion, when a Pain Elemental monster
  dies, the Lost Souls generated by its explosion may be flung through nearby
  walls, where they may become trapped.  Lost Souls that are trapped in walls
  may still be visible, but may be impossible to kill (this has little effect
  on the game, since Lost Souls do not count towards a Kills score).  The voice
  effect that accompanies "victory text" is not heard if Music Volume is turned
  down.  Some monsters on the original PC maps are replaced with different
  monsters on the equivalent maps in this version.  Player may select stereo
  (default) or monophonic audio.  Stereo sounds may occasionally phase-shift,
  giving false impressions of sound sources (for example, during continuous
  firing of the player's chaingun, some of the reports may seem to originate
  from a point to the player's left or right).  Pausing the game does not
  interrupt music.  "DEMO" flashes on the screen while demo games are shown.
  3 demo games are shown during Attract mode (including demos from 2 "secret"
  map levels), then the third demo is repeated once before cycling back to the
  first.  In most Doom/Doom II games that end victoriously with a "parade" (or
  "Cast of Characters"), the parade continues indefinitely until the player
  resets or restarts the game; In Saturn Doom, the parade runs through one
  time, and then the game returns to the Main Menu screen.  The "WOLFENSTEIN"
  and "GROSSE" secret map levels from PC Doom II do not appear in this game.
  The "Commander Keen" character from PC Doom II is not included.  The "Lots of
  Goodies" cheat code will not add keys if they are not necessary.

  however, match an equivalent map in the PSX, Jaguar, 3DO and GBA Doom 1
  games.)

5. NINTENDO 64 DOOM 64
======================
o Note that Doom 64, unlike other game-console Doom games, is not a direct port
  or conversion of an existing PC Doom game.  It does, however, share many of
  the same features and functions that exist in all other Doom/Doom II games.

o A Nintendo 64 Control Deck, model NUS-001, equipped with one standard
  Nintendo 64 Controller (model NUS-005), was used as the test system for the
  Doom 64 game described in this document.

o Pros: Comparatively sharp, high-resolution graphics produced through dynamic
  antialiasing.  The "pixelation" effect (a drop in graphics resolution seen in
  other Doom games as the player character approaches a surface or object) is
  notably reduced here.  Features some new graphics effects (fog/mist, fading
  objects, animated skies, etc.).  First-person view fills the entire space on
  the TV/monitor screen (with or without the "status bar" displayed).  The
  "bar" of the "status bar" is invisible: only the numerals used for health,
  ammo and armor (and the icons used for keys) will actually obstruct any part
  of the first-person view.  The status bar may be switched off, allowing only
  the first-person view to fill the screen (an option not found in any other
  console Doom game).  Map level, skill level, health, armor, weapon and ammo
  information is translated to a password code which is given after successful
  completion of each map level (many other console Doom games cannot save such
  information externally).  On the password screen, the last password entered
  or generated may be re-entered with a single button press (useful when, for
  example, a player is killed and wishes to restart the map level with a
  non-default status).  The game supports a "Controller Pak" (a separately-sold
  memory cartridge device) which allows storage and retrieval of up to 16 game
  passwords.  Built-in screen brightness adjustment option, somewhat similar to
  the "Gamma Correction" feature in the PC Doom games.  Automap is dual-mode,
  allowing a player to view the map with a detailed textured floor (using an
  Area's actual floor textures), or view the map as a plain (PC-Doom style),
  untextured Automap.  Extensive controller customizing is allowed (Fire button
  can swap functions with Speed button or Activate button, etc.), including an
  ability to choose and/or modify any one of 5 preset configurations.  Player
  may walk and move in the game with the controller's directional-pad buttons,
  and/or with the controller's built-in joystick.  The player character can
  rotate at varying speeds: turning slowly using controller buttons, marginally
  faster using the joystick, or very fast with the joystick if "Controller
  Stick Sensitivity" is increased through a setting under the game's Options
  Menu.  The game provides a control for "centering" the position of the game
  screen on the display device, allowing horizontal and vertical adjustments.
  Game messages (such as "PICKED UP A BOX OF SHELLS") may be toggled on or off,
  as can be done in the PC Doom games.

o Cons: No multiplayer ability.  On some display devices the first-person view
  may seem too dark, and/or the status bar data may be difficult to read, even
  when the game's brightness level is set to maximum.  Occasionally objects in
  the foreground are partially overlaid by background wall or floor textures.
  Weapons are cyclic-access only.  Game does not save controller, display, or
  sound configuration settings.  Although joystick-based turning speed can be
  greatly increased through a setting under the game's Options Menu, D-pad (or
  button-based) turning speed cannot.  The status bar can only display the ammo
  level of the currently selected weapon (in PC and GBA Doom games, all ammo
  levels for all weapons can be displayed at all times).  Once in Automap mode,
  a player must cycle through both Automap styles to return to the first-person
  view (this can be done almost instantaneously if desired, but must be done
  every time the Automap is accessed).  At 16 characters long, the passwords
  are somewhat cumbersome to enter ("type in"), unless they are stored in a
  separately-sold Controller Pak memory cartridge.  The delay between a player
  character's death and subsequent resurrection is longer here than in most
  other Doom games.

o Miscellaneous: Game by id Software and Midway Home Entertainment, Inc.
  Cartridge format.  32 map levels, none of which are found in the PC Doom
  games.  Gameplay speed is adequate, but some aspects of a player character's
  motion (such as running speed) may be marginally slower here than in a PC
  Doom/Doom II game played on a modern computer.  More monster/enemy variety in
  this game than in most Doom 1-based games (although many Doom 64 monster
  types are copied from PC Doom II).  With some new features and completely
  re-worked graphics, the "look and feel" of this game bears only a distant
  resemblance to all other Doom games.  All enemies have a modified appearance,
  and in some cases are only vaguely similar to their counterparts in other
  Doom or Doom II games.  Virtually all objects and surface textures have been
  changed from their original designs, including power-ups, walls, floors,
  ceilings, switches and teleporters.  Map levels may have structures that
  provide crossing paths at different elevations (such as a solid bridge that a
  player can walk over or under), and similar map features which are not found
  in other Doom games.  Graphics, overall, tend to be darker here than in any
  other version.  Features new music tracks (and other background audio
  effects), not used in the PC games.  Some features appear in this game that
  appear in no other Doom or Doom II game, including horizontally-sliding
  surfaces, wall-mounted monitors that can be used to view distant parts of the
  map, automated traps that launch projectiles, etc.  Doom 64 includes a new
  "Boss" monster (referred to in the game as the "Mother of all Demons") which
  is not found in any other Doom game.  The Spider Mastermind monster found in
  most other Doom games is not included.  Another version of the Imp appears in
  this game: the "Nightmare Imp", which is semi-translucent, darker, and faster
  than the normal Imp, and launches high-velocity fireballs.  Arachnotrons fire
  twin, side-by-side plasma bursts (versus single-stream bursts in all other
  games).  Pain Elemental monsters can release 2 Lost Souls at a time (versus a
  maximum of 1 at a time in all other games).  Lost Souls are semi-translucent
  in this game.  The "Demon" monster (a pink, muscular, hunched-over, biting
  monster), is referred to as a "Bull Demon" in the manual included with the
  game.  A new laser-type weapon appears in this game, and uses the same "cell"
  ammunition as a plasma rifle or BFG 9000.  Doom 64 includes a unique type of
  power-up (referred to in this document as a "Demon Artifact") which acts both
  as an enhancement for the new laser weapon, and as a special key/activator
  for use in the game's final map level.  Demon Artifacts have an appearance
  somewhat similar to the demon/pentagram graphic which is used both in the
  game's tally screens and on the cover of the game's manual.  A total of 3
  Demon Artifacts are hidden among the maps of Doom 64.  When a Demon Artifact
  is picked up, an icon representing the Artifact appears at the lower-right
  corner of the Automap screen.  A double-barrelled "Super Shotgun" (similar to
  the one found in "Doom II" games) appears in this game.  The double-barrelled
  shotgun and the rocket launcher both have a "kick" when fired, giving a
  slight backwards push against the player character.  In this game, the plasma
  rifle tends to make a continuous buzzing noise whenever it is selected as the
  current weapon.  In this game, the chain saw has a pair of blades, side by
  side (versus a single blade in all other Doom games).  In all other Doom
  games, only players and monsters can be teleported from place to place; In
  Doom 64, other objects (power-ups, weapons, and structures) may also be moved
  from place to place, or fade in and out of existence.  On occasion, some
  monsters may spontaneously "fade in" to a location on the current map (an
  effect similar to teleportation).  Game information stored in a password code
  may be inaccurate (health, armor and ammo level numbers tend to be rounded).
  Monster and weapon sounds tend to differ from the sounds used in the PC games
  (in fact, most sound effects are identical to those used in the PlayStation
  Doom games, which were released prior to Doom 64).  The sound effect used in
  PSX Doom for an item respawning during a Deathmatch game is used in this game
  to indicate that a monster or item is "fading into" (or "spawning into") a
  nearby location.  In this game, "blurred" objects are translucent and faded,
  but otherwise maintain their normal colors and surface features (in the PC
  games, "blurred" objects, when visible, are a translucent gray, with a flat,
  flowing/scrambled surface).  Explosive barrels are not mentioned in the game
  manual, but do appear in this Doom game, as they do in all other Doom games.
  The "marine face", seen in the status bar of all other Doom/Doom II games, is
  missing from this version.  "Secret areas" are usually announced (via
  on-screen messages) as a player character enters them.  While walking/running
  in Automap mode, the player icon does not turn to change direction; instead,
  the Automap rotates around the icon, which is always facing north.  In this
  game, the "radiation shield" appears as a green "biohazard" symbol, instead
  of as the white full-body "radiation suit" seen in all other Doom games.  A
  Spectre Demon is opaque until it discovers a player character, whereupon it
  becomes translucent.  If a translucent Spectre Demon is killed, its body
  becomes opaque.  The physical location of an item on a given map can vary
  with the skill level that the map is played on (for example, the blue keycard
  in the STAGING AREA map is in an open area when the game is played on skill
  1, but is located in a small, closed room on skill 4).  Doom 64 uses skill
  level names unique among console Doom games: "BE GENTLE!", "BRING IT ON!", "I
  OWN DOOM!", and "WATCH ME DIE!".  Some surfaces with 1-way transparency are
  used in this game (a feature otherwise found only in PC Doom games and GBA
  Doom II).  In Doom 64, entering a valid map 1 password, or using a special
  exit on map 32, will reveal a hidden "Features Menu", which allows access to
  various cheat functions.  On occasion, the first-person view will shake as an
  indication of a change in the current map level (changes in map topography,
  structures, etc.).  When the player fires a weapon, the first-person display
  can jump or vibrate with the weapon's recoil.  Every 30 seconds of idle time
  after a player character dies, the game will display one of 12 "taunts" (such
  as "HAHAHAHA!" or "HAVE YOU HAD ENOUGH?").  The double-barrelled shotgun
  reloads without being broken open (an animated sequence seen in Doom II-based
  games); however the weapon's load time remains comparable to that of the
  other games.

6. ATARI JAGUAR DOOM
====================
o An Atari Jaguar 64-Bit Interactive Multimedia System, equipped with one
  standard Jaguar controller, was used as the test system for the Atari Jaguar
  Doom game described in this document.  For testing multiplayer games, the
  system was hooked to an identical system via the Jaglink Interface cable.
  Multiplayer games were then tested with identical systems hooked together
  via a pair of linked Catbox interface devices (sold separately by ICD, Inc.).

o Pros: 2-player ability (although multiplayer function may be unstable).  The
  first-person view and status bar combination fills the entire display space
  on the TV/monitor screen.  Some controller customizing allowed (Fire button
  can swap functions with Speed button or Activate button, etc.).  Memory built
  into the game cartridge automatically stores controller configuration
  settings, the sound volume setting, the current skill level setting, and also
  stores the map level numbers of all Areas that were successfully conquered
  (except Area 24).  When first starting up the game, a player may choose to
  start play on any of 23 map levels previously conquered (this is a quick
  process, as there are no passwords to keep or re-enter), and may choose a
  different skill level to play it at.  During a game in progress, weapons are
  direct-access.  The built-in cheat codes may be entered quickly and easily
  (for example, an invincibility cheat code is 3 button-presses on the Jaguar,
  5 on the PC, 10 on the PlayStation).  The Jaguar Doom game comes with a
  plastic overlay which fits into the top of the game controller, providing
  labels and weapon icons for the buttons on the controller's keypad.

o Cons: Games in progress cannot be saved (but a player may start a new game on
  any of 23 map levels previously conquered).  As stated in the game manual,
  occasional "Network Errors" can occur during Deathmatch and Cooperative
  games, causing the game in progress to start over again on the current map
  level.  Only 7 monster types in the game (tying with the Sega 32X and GBA
  games for least variety).  No Spectre Demon.  No Cyberdemon or Spider
  Mastermind monsters.  No Blur Artifacts.  No light-amplification visors.  No
  crushing ceilings.  No music during play.  Somewhat lower graphics resolution
  than some other full-screen console Doom games.  The status bar can only
  display the ammo level of the currently selected weapon (in PC and GBA Doom
  games, all ammo levels for all weapons can be displayed at all times).

o Miscellaneous: Port by id Software.  Cartridge format.  24 map levels, 2 of
  which are not found in PC Doom games.  Adequate graphics resolution and
  quality.  Gameplay speed is adequate, but can be somewhat slower than a PC
  Doom/Doom II game played on a modern computer.  Map level layouts in this
  game are very similar to the equivalent maps in the PSX, Saturn, 3DO, Sega
  32X and GBA Doom 1 games.  Rocket and barrel explosions can penetrate solid
  walls and doors (allowing a player to kill some enemies without ever directly
  encountering them).  Health potions and Spiritual Armor bonuses add 2% to a
  player's health or armor (versus 1% in the PC games).  Picking up an
  Invulnerability Artifact tints the screen bluish-pink, as opposed to the
  white-out effect seen in many other versions.  In 2-player games, both player
  characters wear a green uniform.  In Deathmatch games, the Frag counts for
  both players are displayed in each player's status bar.  Corrosive floors
  (slime, etc.) will decrease a player's health quickly (faster in this version
  of Doom than in most other versions running at a comparable skill level).
  When the "Happy Ammo" cheat code is used, the player attains an ammo level of
  500 rounds for every weapon (versus a specific individual ammo level for each
  weapon in the PC games).  Game manual is in 3 languages: English, French,
  German.  Game manual states that cartridge memory will not accept more than
  100,000 changes to stored information (however this would still allow, for
  example, 50 changes a day for more than 5 years).

  The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
  "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
  The Jaguar "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No
  Jaguar equivalent exists for the PC "DIS" map.
  The Jaguar "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map.
  (It does, however, match the "TOWER OF BABEL" map in the 3DO and GBA Doom 1
  games, and the "HELL GATE" map in the PSX and Saturn games.)
  The Jaguar "HELL KEEP" map does not match the PC "HELL KEEP" map.  (It does,
  however, match an equivalent map in the PSX, Saturn, 3DO and GBA Doom 1
  games.)

7. 3DO (PANASONIC AND OTHERS) DOOM
==================================
o A Panasonic REAL 3DO Interactive Multiplayer, model FZ-1, equipped with one
  standard Panasonic 3DO controller (model FZ-JP1X), was used as the test
  system for the 3DO Doom game described in this document.

o Pros: Some controller customizing allowed (Fire button can swap functions
  with Speed button or Activate button, etc.).  Ability to choose between 4
  window sizes (or 6, when using a cheat code) for the first-person view.  3DO
  system memory automatically stores controller configuration settings, the
  sound volume setting, the current skill level setting, the selected window
  size for the first-person view, and also stores the map level numbers of all
  Areas that were successfully conquered (except Area 24).  When first starting
  up the game, a player may choose to start play on any of 23 map levels
  previously conquered (this is a quick process, as there are no passwords to
  keep or re-enter), and may choose a different skill level to play it at.

o Cons: Games in progress cannot be saved (but a player may start a new game on
  any of 23 map levels previously conquered).  No multiplayer ability.  Game
  animation speed can be very choppy, with frequent micro-pauses to access the
  CD, and animation noticeably slows down and speeds up with variances in the
  number of on-screen textures and sprites.  No Cyberdemon or Spider Mastermind
  monsters.  No light-amplification visors.  No crushing ceilings.  Weapons are
  cyclic-access only.  First-person view does not fill the entire space above
  the status bar.  Game does not utilize all available display space on the TV/
  monitor screen.  The status bar can only display the ammo level of the
  currently selected weapon (in PC and GBA Doom games, all ammo levels for all
  weapons can be displayed at all times).

o Miscellaneous: Port by Logicware and Art Data Interactive.  CD format; 1 CD.
  24 map levels, 2 of which are not found in PC Doom games.  Good graphics
  resolution and quality.  Gameplay speed, overall, is below the average speed
  of most other versions.  Map level layouts in this game are very similar to
  the equivalent maps in the PSX, Saturn, Jaguar, Sega 32X and GBA Doom 1
  games.  Features many of the music tracks from PC Doom, re-mastered with new
  and more distinctive instrumentation.  A built-in cheat code allows the
  first-person view window to be expanded two more times beyond the default
  maximum size (however, larger windows further slow down the game).  The game
  box for 3DO Doom advertises "full screen display", and the first-person view
  is indeed maximized within a window; but the window itself (when expanded to
  any size) is always bordered by static artwork.  Rocket and barrel explosions
  can penetrate solid walls and doors (allowing a player to kill some monsters
  without ever directly encountering them).  Health potions and Spiritual Armor
  bonuses add 2% to a player's health or armor (versus 1% in the PC games).  In
  this game, "blurred" objects are a translucent gray, with a plain, flat
  surface (in the PC games, "blurred" objects, when visible, are a translucent
  gray, with a flat, flowing/scrambled surface).  If the "Map All Things" cheat
  code is used, monster orientations are not indicated as they are in other
  versions that support this cheat code; All object indicators point in the
  same direction.  The "marine face" in the status bar always explodes when the
  player character dies.  Music from the first map level accompanies the tally
  screens.  No "Attract mode"; no demo games.  When the "Happy Ammo" cheat code
  is used, the player attains an ammo level of 500 rounds for every weapon
  (versus a specific individual ammo level for each weapon in the PC games).

8. SUPER NINTENDO DOOM
======================
o A Super NES Control Deck, model SNS-001, equipped with one standard Super NES
  controller (model SNS-005), was used as the test system for the SNES Doom
  game described in this document.  For testing multiplayer games, the system
  was connected to various similar systems via the X Band network, using a
  Catapult X Band modem device (model 00100).

o Pros: Basic map layouts tend to match the equivalent PC-game maps with
  above-average accuracy (higher accuracy, overall, than that found in every
  other console version).  Simplified Deathmatch ability via X Band Network
  connection.  SNES Doom includes both the Spider Mastermind and Cyberdemon
  monsters from the original PC games (one or both of these are missing from
  most other console games).  The Automap is actively updated at all times,
  whether displayed or not (in most other Doom versions, the Automap cannot be
  updated while displayed).

o Cons: Games in progress cannot be saved.  Comparatively low-resolution
  graphics (most noticeable with distant objects); lowest overall resolution of
  all large-screen Doom games.  Cannot play Episodes 2 or 3 using low skill
  levels.  For multiplayer games, a separately-sold "X Band" modem device (and
  a subscription to the X Band Network) is/was required for each player's game
  system.  Cooperative games are not supported.  Deathmatch games are scaled
  down in this version (items do not re-spawn, no sound effects, an enemy
  player character simply disappears from the Area when killed, exiting a map
  level displays the main menu, where both players must select which map to
  restart the game on, and weapons, ammo, etc., cannot be carried between map
  levels).  Can only start a new single-player game from map level 1 (although
  a player may start on the first map of any Episode); Map level passwords and
  warp cheat codes are not supported.  Shotguns or ammo clips dropped by killed
  enemies do not appear on the ground.  No controller customizing allowed.  No
  real textures for ceilings or floors (including corrosives and teleporters).
  Monsters can only display a front side.  No Spectre Demon.  Weapons are
  cyclic-access only (although weapons may be cycled while the game is paused).
  Weapon choices can cycle in 1 direction only.  Cannot save game configuration
  settings.  Game does not utilize all available display space on the TV/
  monitor screen.  Sounds from events at medium or long range are often cut
  short or cannot be heard.  Although monsters can hurt each other, they cannot
  deliberately fight each other.  No screen-flash warning as an Invulnerability
  Artifact or radiation suit begins to wear out.  The status bar can only
  display the ammo level of the currently selected weapon (in PC and GBA Doom
  games, all ammo levels for all weapons can be displayed at all times).

o Miscellaneous: Port by Sculptured Software, Inc.  Cartridge format.  22 map
  levels, all of which are found in PC Doom games.  Gameplay speed is adequate,
  but is slower than a PC Doom/Doom II game played on a typical modern
  computer.  No "Attract mode"; no demo games.  A bug in the game allows the
  player to instantly acquire additional weapons once a chain saw has been
  picked up.  In most Doom versions, a killed player restarts a map level with
  100% health, 0% armor, a pistol and 50 bullets; In SNES Doom, a killed player
  restarts with 100% health, and whatever armor, weapons and ammo that the
  player originally brought into the level.  While walking/running in Automap
  mode, the player icon does not turn to change direction; instead, the Automap
  rotates around the icon, which is always facing north (this is also how
  Automap "scrolling" is handled).  Some monsters tend to be easier to kill
  than their counterparts in other versions of the game.  A player may still
  pick up weapons after ammo levels are at maximum (for example, a player may
  pick up multiple shotguns even after reaching the maximum carry limit of 100
  shells).  Weapons are cycled in the following order: Fist, pistol, shotgun,
  chain saw, chaingun, rocket launcher, plasma rifle, BFG 9000, then fist
  again, and so on.  In this game, "blurred" objects are translucent and faded,
  but otherwise maintain their normal colors and surface features (in the PC
  games, "blurred" objects, when visible, are a translucent gray, with a flat,
  flowing/scrambled surface).  Hitting the Activate/Use button can still
  trigger the "grunt" sound effect, even when the player character is nowhere
  near a wall, switch, or door.  No exploding-monster effect (usually seen in
  PC Doom games when, for example, an Imp or Former Human is hit by a rocket).
  Teleportation is instantaneous, without the motion-damping effect seen in
  other versions.  No "green spark" effect when a player or monster goes
  through a teleporter.  Impacts of bullets or shells on walls are not visible.
  No doors or switches are activated by projectile impacts.  An Artifact or
  power-up can be picked up when the player walks over it, but can also be
  picked up if the player is jumping (running) through the airspace above it.
  A weapon icon appears in the player's status bar to show which weapon is
  currently held.  In most Doom games, a typical monster will make an "alert"
  sound when it first senses a player, and a "growl" sound when patrolling an
  area after being alerted; In the SNES game, a monster's "alert" sound is also
  used for the "growl" sound.  Monster projectiles may affect other monsters in
  ways contrary to what is seen in other Doom games.  A Cyberdemon's rockets
  appear to fly backwards.  The player's chaingun fires fewer bullets than what
  is indicated by the firing sound.  In SNES Doom, a minimal burst of chaingun
  fire is typically 1 bullet (with 2 reports), versus 2 bullets in all other
  Doom games.  A BFG 9000 will use up to 40 energy cells per shot, but can be
  fired when less than 40 cells remain (other Doom versions require a minimum
  of 40 cells).  In most Doom games, an elevator/lift will reverse if a player
  or monster prevents it from rising to its highest position; In the SNES game,
  a blocked elevator will simply halt in place, and only move again when the
  obstacle is removed.  Some secret doors are better camouflaged in this
  version than in PC Doom.  Players and monsters do not move laterally as a
  result of impacts or nearby explosions (as they do in all other Doom games).
  Phobos/Deimos/Hell landscapes are used as the background for the tally
  screens between map levels, showing the player's progress through the various
  stages of each Episode (SNES Doom and GBA Doom are the only console versions
  that use these graphics).  Most of the original PC Doom story text appears in
  this game.  No scrolling/sliding textures, as are found in all other Doom
  games.  No built-in volume controls.  No built-in cheat codes, but some codes
  are available for use with the Super NES Game Genie device (sold separately
  by Galoob Toys, Inc.).

  Notes: The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to
  as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
  The "E#M#" designators used here for SNES Doom maps are for reference only,
  and are not displayed in the actual game.

o Index General PC PSX Saturn N64 Jaguar 3DO SNES 32X GBA GBA 2 Tables Glossary

9. SEGA GENESIS 32X DOOM
========================
o A Sega Genesis System Console, model 1601, equipped with one standard Sega
  Genesis "6-button" controller (model MK-1653), and one Sega Genesis 32X
  module (model MK-84000A), was used as the test system for the Sega 32X Doom
  game described in this document.

o Pros: Player can always start a game on any of 15 map levels.  The Automap is
  actively updated at all times, whether displayed or not (in most other Doom
  versions, the Automap cannot be updated while displayed).  Some controller
  customizing allowed (Fire button can swap functions with Speed button or
  Activate button, etc.).  With a "6-button" controller attached, weapons can
  be accessed directly, or weapon choices can be cycled in both directions.

o Cons: Requires both a Sega Genesis system and the "32X" expansion module.
  This version has the least map levels of all Doom games.  Games in progress
  cannot be saved (but a player may always start a new game on any of 15 maps).
  No multiplayer ability.  No BFG 9000 weapon available without using a cheat
  code.  Monsters can only display a front side (despite the fact that screen
  shots on the game box and the 32X module box show side views of monsters).
  Only 7 monster types in the game (tying with the Jaguar and GBA games for
  least variety).  No Spectre Demon.  No Cyberdemon or Spider Mastermind
  monsters.  No Blur Artifacts.  No light-amplification visors.  No crushing
  ceilings.  With a "3-button" (standard) controller, weapons are cyclic-access
  only, and weapon choices can be cycled in only 1 direction.  Cannot save game
  configuration settings.  First-person view does not fill the entire space
  above the status bar.  Game does not utilize all available display space on
  the TV/monitor screen.  Although monsters can hurt each other, they cannot
  deliberately fight each other.  Infrequent, brief flashes of graphics "noise"
  may sometimes be seen in the active-graphics window (first-person view or
  Automap).  Some rooms in some map levels are inaccessible.  The few built-in
  cheat codes can be difficult to implement (button combinations may have to be
  pressed many times before a code will take effect).  The use of cheat codes
  may prevent access to maps 16 and 17, and prevents the game's full ending
  sequence from being shown.  The status bar can only display the ammo level of
  the currently selected weapon (in PC and GBA Doom games, all ammo levels for
  all weapons can be displayed at all times).

o Miscellaneous: Port by id Software.  Cartridge format.  17 map levels, all of
  which are found in PC Doom games.  Decent graphics resolution and quality.
  Gameplay speed is adequate, but can be somewhat slower than a PC Doom/Doom II
  game played on a modern computer.  Maps 16 and 17 can only be accessed if the
  game was started on map 1, and if cheat codes were not used during the game.
  In order to see the game's entire ending sequence, a player must start on map
  level 1 and play the game all the way through without using cheat codes (a
  game won any other way will result in the credits being shown, and then the
  game simply halts with a plain textured screen and a "DOS prompt").  Contrary
  to what is stated in the game manual, a player cannot enter map 1 from map
  15; map levels do not "wrap around".  Map level layouts in this game are very
  similar to the equivalent maps in the PSX, Saturn, Jaguar, 3DO and GBA Doom 1
  games.  Rocket and barrel explosions can penetrate solid walls and doors
  (allowing a player to kill some monsters without ever directly encountering
  them).  Health potions and Spiritual Armor bonuses add 2% to a player's
  health or armor (versus 1% in the PC games).  Picking up an Invulnerability
  Artifact causes a drop in graphics chroma, as opposed to the white-out effect
  seen in many other versions.  Picking up a Berserk Pack causes a relatively
  bright, sustained flash of red, which may be mistaken for the effect seen
  when the player character takes sudden, heavy damage.  Shotgun-loading sound
  is played (sometimes very softly) for a teleportation event, instead of the
  teleport sound heard in most other versions.  Map levels have no names, only
  numbers.  Map numbers are only indicated in the tally screens, not while
  playing a map level.  In the Automap, the player icon (an arrow) looks like
  the one used in the PC games, as opposed to the green triangle used in all
  other console versions of Doom.  There is an option in Automap mode to turn
  on a grid which overlays the map, and can be used as a reference for scale (a
  feature otherwise found only in the PC games).  Rockets fired from a player's
  rocket launcher appear to fly backwards (the nose of the rocket faces the
  player as the rocket moves away).  All monsters, items and Artifacts located
  in very dark areas remain well lit at all times.  Not all teleporters
  function (but all important ones do).  Because graphics are only provided to
  show the front side of objects, some monsters in "wait" mode may seem blind
  when a player approaches them from behind (a monster will always appear to
  look at a player even when it is not facing the player).  When the "Happy
  Ammo" cheat code is used, the player attains an ammo level of 500 rounds for
  every weapon (versus a specific individual ammo level for each weapon in the
  PC games).

o Index General PC PSX Saturn N64 Jaguar 3DO SNES 32X GBA GBA 2 Tables Glossary

10. NINTENDO GAME BOY ADVANCE DOOM
==================================
o A Nintendo Game Boy Advance, model AGB-001, was used as the test system for
  the GBA Doom game described in this document.  For testing multiplayer games,
  the system was connected to identical systems via one or more Nintendo Game
  Boy Advance Game Link cables (model AGB-005).

o Pros: The Game Boy Advance has a built-in screen, battery pack and link port,
  making GBA Doom the most portable version among all console Doom 1 games.
  Multiplayer link ability, allowing 2 players in Cooperative games, and 2 to 4
  players in Deathmatch games.  Includes 8 Deathmatch-only bonus maps not found
  in other commercial Doom games.  Some flaws have been corrected in some maps
  which were copied from earlier console Doom games.  Games in progress may be
  saved to any of 4 save-game slots in the Doom Game Pak, and save-game data
  includes controller, lighting and audio settings.  2 lighting-style choices,
  "Dynamic" (normal), and "Static" (low light levels are increased, and lights
  that normally flash are always on).  6-level "Brightness" adjustment option
  (somewhat similar to the "Gamma Correction" feature in the PC Doom games),
  which controls the maximum brightness of both Dynamic and Static lighting
  modes.  Includes an "Autorun" option (player always runs).  In the status
  bar, current ammo levels and ammo limits are always displayed for all weapons
  (in most other console Doom games, only the currently selected weapon can
  have an ammo level displayed).  Some controller customizing allowed (any of 6
  preset button configurations may be selected).

o Cons: The original Game Boy Advance does not have any built-in lighting for
  its screen, which means that GBA Doom can be difficult to view unless the
  right amount of external light is hitting the screen at the right angle at
  all times (a newer model of the GBA, the GBA SP, does have built-in screen
  lighting).  Saved games may occasionally become corrupted, and fail to reload
  correctly.  Cooperative games have a 2-player limit, even when 3 or more GBAs
  are linked.  Only 7 monster types in the game (tying with the Jaguar and Sega
  32X games for least variety).  No Spectre Demon.  No Cyberdemon or Spider
  Mastermind monsters.  No Blur Artifacts.  No light-amplification visors.  No
  crushing ceilings.  Weapons are cyclic-access only.  In some of the preset
  button configurations weapon-swapping can be awkward, or weapon changes may
  occur unintentionally when strafing or performing other maneuvers.  Some
  rooms in some map levels are inaccessible.  The sound effect used to indicate
  a player taking damage is also mistakenly used whenever a player lands unhurt
  after falling a short distance.  Frag counts for players in Deathmatch games
  are only displayed in the Automap view.  No tally screen is displayed, and no
  opportunity to save the game is given, when a player goes through the exit to
  the Military Base map level.

o Miscellaneous: Port by id Software, David A. Palmer Productions, and
  Activision.  Cartridge format.  32 map levels, 10 of which are not found in
  PC Doom games.  Decent graphics resolution and quality for the GBA screen.
  Gameplay speed is adequate, but is somewhat slower than a PC Doom/Doom II
  game played on a modern computer.  The game's overall speed can be affected
  by the built-in lighting options: Dynamic Lighting may lower the framerate,
  while Static Lighting may raise it.  Map level layouts in this game are very
  similar to the equivalent maps in the PSX, Saturn, Jaguar, 3DO and Sega 32X
  games.  No "Attract mode"; no demo games.  No "Ultra-Violence" skill setting;
  the highest skill is "Nightmare".  Player can select the fist weapon at any
  time, whether or not a chain saw or Berserk Pack has been acquired.  When
  monsters or players are killed, their corpses disappear after a brief delay.
  Monster and player blood is green instead of red.  All monsters, items and
  Artifacts located in very dark areas remain well lit at all times.  When a
  pink Demon is killed, it makes the same sound as a dying Imp (in all other
  Doom games, Imps and Demons make separate sounds).  Sound effects produced by
  distant events may be played at an undiminished volume, and/or may penetrate
  walls or areas that are soundproof in other Doom games.  No exploding-monster
  effect (usually seen in PC Doom games when, for example, an Imp or Former
  Human is hit by a rocket).  Rocket and barrel explosions can penetrate solid
  walls and doors (allowing a player to kill some enemies without ever directly
  encountering them).  Teleportation is almost instantaneous, without the
  motion-damping effect seen in other versions.  In a reversal of the Automap
  colors used in most other Doom games, GBA Doom's Automap displays "viewed"
  surfaces as gray lines, while "unseen" surfaces (added to the Automap when a
  Computer Area Map Item is acquired) are displayed in red.  The Automap screen
  allows 5 preset zoom levels.  Health potions and Spiritual Armor bonuses add
  2% to a player's health or armor (versus 1% in the PC games).  Picking up an
  Invulnerability Artifact tints the screen blue, as opposed to the white-out
  effect seen in many other versions.  Unlike all other console Doom games,
  Lost Souls are calculated in the Kills score displayed in the tally screens.
  The tally screen shows both the time spent on the map and the map's Par Time.
  Phobos/Deimos/Hell landscapes are displayed between map levels, showing the
  player's progress through the various stages of each Episode (GBA Doom and
  SNES Doom are the only console versions that use these graphics).  The "YOU
  ARE HERE" indicators in the landscape screens do not always point to the
  correct areas.  When the "Happy Ammo" cheat code is used, the player attains
  an ammo level of 500 rounds for every weapon (versus a specific individual
  ammo level for each weapon in the PC games).  In this game the player's fist
  makes an impact noise when striking a wall or other inanimate object (in most
  other Doom games, a fist impact on an inanimate object is silent).

  Notes: Map equivalency is based on general map layouts, not map names.
  The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
  "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
  The GBA "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No GBA
  equivalent exists for the PC "DIS" map.
  The GBA "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map.  (It
  does, however, match the "TOWER OF BABEL" map in the Jaguar and 3DO games,
  and the "HELL GATE" map in the PSX and Saturn games.)
  The GBA "HELL'S KEEP" map does not match the PC "HELL KEEP" map.  (It does,
  however, match an equivalent map in the PSX, Saturn, Jaguar and 3DO games.)

11. NINTENDO GAME BOY ADVANCE DOOM II
=====================================
o A Nintendo Game Boy Advance, model AGB-001, was used as the test system for
  the GBA Doom II game described in this document.  For testing multiplayer
  games, the system was connected to identical systems via one or more Nintendo
  Game Boy Advance Game Link cables (model AGB-005).

o Pros: The Game Boy Advance has a built-in screen, battery pack and link port,
  making GBA Doom II the most portable version among all console Doom II games.
  GBA Doom II features more maps and monster types than the DOOM II Episodes of
  PlayStation Doom or Saturn Doom.  Multiplayer link ability, allowing 2
  players in Cooperative games, and 2 to 4 players in Deathmatch games.  Games
  in progress may be saved to any of 4 save-game slots in the Doom II Game Pak,
  and game data includes controller, lighting and audio settings.  Includes a
  6-level "Gamma" adjustment option to control the overall brightness of the
  game screen.  Controller customizing includes 4 preset button configurations,
  a 5-level "Sensitivity" adjustment option to control the player character's
  pivoting speed, and an "Always Run" option (player always runs).  In the
  status bar, current ammo levels and ammo limits are always displayed for all
  weapons (in most other console Doom games, only the currently selected weapon
  can have an ammo level displayed).  The "Happy Ammo" cheat code provides a
  backpack (in most other Doom games, a backpack is not provided, or a player's
  existing backpack is removed).

o Cons: The original Game Boy Advance does not have any built-in lighting for
  its screen, which means that GBA Doom II can be difficult to view unless the
  right amount of external light is hitting the screen at the right angle at
  all times (a newer model of the GBA, the GBA SP, does have built-in screen
  lighting).  On rare occasions the game may freeze, and the Game Boy Advance
  must be powered down and restarted.  Cooperative games have a 2-player limit,
  even when 3 or more GBAs are linked.  Occasionally a player weapon used on a
  close-range target will auto-aim towards the ceiling/sky or floor.  In some
  of the preset button configurations, weapon-swapping can be awkward, or
  weapon changes may occur unintentionally when strafing or performing other
  maneuvers.  Weapons are cyclic-access only.  The auto-aim ability of monsters
  can remain unaffected when a player picks up a Blur Artifact.  Damage to a
  player's armor may not always be accurately represented in the status bar
  display.  Frag counts for players in Deathmatch games are only displayed in
  the Automap view.  Unlike the PC Doom/Doom II games, a player's running speed
  is slower in reverse than when moving forward.

o Miscellaneous: Port by id Software, Torus Games, and Activision.  Cartridge
  format.  34 map levels, all of which (in whole or in part) are found in PC
  Doom II.  Decent graphics resolution and quality for the GBA screen.
  Gameplay speed is adequate, but is somewhat slower than a PC Doom/Doom II
  game played on a modern computer.  No "Attract mode"; no demo games.  No
  "Ultra-Violence" skill setting; the highest skill is "Nightmare!".  GBA Doom
  II maps reflect some features found in maps from older versions of PC Doom II
  (currently the latest version of PC Doom II is v1.9).  In this game some maps
  have minor alterations, such as elevators replacing stairs, and strategically
  placed barriers or deleted windows in order to reduce the maximum number of
  objects that need to be drawn at any given time.  Some maps in this game have
  major alterations, such as deleted buildings; but in general there are fewer
  large ommisions than in many other console Doom games.  The PC Doom II maps
  INDUSTRIAL ZONE and THE CHASM are each split into 2 "half" maps in this game.
  When computing collision detection in this game, most non-structural objects
  have a comparatively narrow diameter, which allows some objects (such as
  players and monsters) to move very close together, or push past one another,
  where they could not in PC Doom II.  Unlike most other Doom games, monsters
  in this game cannot open doors.  Monsters and players may occasionally cross
  above/below one another (a player may even stand on top of a monster, which
  is something that does not occur in most other commercial Doom games).  Some
  monsters on some map levels are "blind" or "deaf" where equivalent PC Doom II
  monsters are not.  A monster's "sensory range" is foreshortened in this game
  (monsters cannot see or hear as far as they can in PC Doom II or most other
  Doom games).  An active monster may halt in place if enough distance accrues
  between the player and monster.  Monsters can remain inactive even while
  being attacked by a player at long range.  When monsters are killed, their
  corpses flash and disappear after a brief delay.  Arch-Viles may resurrect
  killed monsters, even after the monster corpses have disappeared.  Mancubus
  monsters are incapable of aiming vertically, and will always launch their
  fireballs in a wide and predetermined spread.  Revenants only fire homing
  missiles, which are smokeless (in PC Doom II, Revenants can fire 2 missile
  types: a smoking homing missile, and a smokeless non-homing missile).  Unlike
  most other Doom games, monsters such as Imps or Demons cannot scratch or bite
  a player from very high/low adjacent areas.  Floating/flying monsters may not
  always change altitude to attack a target, or may fail to rise again after
  dropping in pursuit of a target.  Monsters may continue to try to attack dead
  players.  Some monster sound effects are missing, such as the walking sounds
  for Arachnotrons and Cyberdemons.  Common bullet-firing sounds are used when
  the Chaingunner enemy fires (in PC Doom II, a shotgun sound is used).  The
  sounds used during an Arch-Vile attack are reversed from sounds used in PC
  Doom II (in this game, the "boom" sound of a completed attack precedes the
  "burning" sound of an attack in progress).  Some player/monster weapons have
  slightly modified firing strengths or rates.  Bullet and pellet impact
  patterns differ somewhat from those in other Doom games.  Monster blood is
  green instead of red.  Player characters do not bleed when injured; their
  blood-spatter sprites are replaced here by "bullet puffs" (the sprites used
  for bullet impacts on solid surfaces).  No exploding-monster effect (usually
  seen in PC Doom games when, for example, an Imp or Former Human is hit by a
  rocket).  Rocket explosions and plasma bursts can trigger impact-activated
  switches (in most other Doom/Doom II games these projectiles will not affect
  switches).  Unlike other Doom games, close-range explosions caused by player
  rockets will not push against the player.  Unlike PC Doom games, players can
  change direction and speed laterally while falling/moving through the air.
  Hitting the Activate/Use button can still trigger the "grunt" sound effect,
  even when the player character is nowhere near a wall, switch, or door.  Some
  surfaces with 1-way transparency are used in this game (a feature otherwise
  found only in PC Doom games and Doom 64).  "Secret areas" are usually
  announced (via on-screen messages) as a player character enters them.  In GBA
  Doom II, almost all retrievable items on a given map level are tallied in the
  Items score (in most other Doom/Doom II games many retrievable items are not
  tallied).  The tally screen shows both the time spent on the map and the
  map's Par Time.  All Items/power-ups will respawn in Deathmatch, including
  Invulnerability Spheres, Blur Artifacts, and Megaspheres (in PC Doom games,
  not all Item types will respawn).  Some symbols and images from the secret
  maps in PC Doom II are altered in the equivalent GBA Doom II maps.  Objects
  suspended from ceilings (bodies or body parts on chains, etc.) do not appear,
  as they do in equivalent PC Doom II maps.  Some item names are misspelled
  (MEDIKIT spelled MEDKIT), or are spelled differently in different places
  (ARMOR/ARMOUR).

  separate maps (parts "A" and "B").

  Notes: Map equivalency is based on general map layouts, not map names.
  (Examples: The PSX "HELL KEEP" map is not considered a match for the PC "HELL
  KEEP" map, as the two map layouts are completely different; And although the
  Jaguar game has no map named "FORTRESS OF MYSTERY", the Jaguar's "DIS" map
  layout does match that of the PC "FORTRESS OF MYSTERY" map.)
  The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as
  "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.
