BUG: While testing the game, programmer Bill Fisher
noticed that sometimes you would be hyperspaced (seemingly at random). He and his boss, Mike Minkoff, went
over the code with a fine-tooth comb before realizing what the problem was: the
Intellivision hand controllers encode button presses in such a way that an
action (side) key pressed at the same time as particular directions on the disc
will be interpreted instead as a numeric key being pressed.
There was no software way around this; shooting while moving would occasionally
be interpreted as pressing 9 -- the hyperspace button.
After several days of puzzling over a solution, the bug was ultimately
"fixed" by including the following note in the instruction manual:
"Every once in a while, your space hunter will
move near a 'black hole,' and the computer will automatically put him into
HYPERSPACE. This will cost you the same number of points as if you had pressed
the HYPERSPACE key yourself. On the other hand, it will save your hunter."
