Would it not be fair to say that, because the Saturn version of OutRun ported by Rutubo Games in 1996 has a 'smooth mode' allowing it to run at 60FPS, twice the framerate of Sega-AM2's original 1986 coin-op arcade machine which indeed was originally 30FPS and also (in the Japanese Saturn version) has completely remixed arranged music, it is the best version of the classic 1986 OutRun available on any format?
The 60FPS smooth mode is acomplished by:
Going to Options, highlight Game Mode,
hold A + C, press Left or Right.
As I said, the original coin-op arcade machine / PCB cannot run at 60FPS, it is locked at 30FPS. And while there have been a number of re-releases of the original sprite-based 2D OutRun on Dreamcast & Xbox (Shenmue II, Yu Suzuki Game Works Vol 1, OutRun2) there is no version that runs at 60FPS, other than the Saturn version... Not counting possible settings in emulators like MAME where it may (or may not) be able to speed things up with the original arcade ROM (I have not looked into this so I don't know).
Thank you Rutubo Games for improving on AM2's classic with a 60FPS mode which looks beautiful and thank you Hiroshi Miyauchi for composing remixed music.
I realize that the U.S. and Euro versions released in 1997 (Sega Ages 3-in-1 ) lost the new remixed music, they only have arcade music, but they still retain the 60FPS framerate, thankfully.
BTW, here is a probably-incomplete list of classic OutRun games released *excluding* the sequels like Turbo OutRun, OutRun 2019, OutRunners, OutRun2 and its many variants etc. If I missed any, let me know so I can update this list.
