The game must be separated between Japan and NTSC/PAL due these reasons:
1- Score in Japan is displayed as XXXX XXXX while in NTSC/PAL as XXXXXXXX. 2- Players who finish the game in NTSC/PAL must take the proof fast because once the credits of game starts, score won't be available anymore while in Japan score is displayed again when credits finishes. 3- Final reward between versions is very huge, look at these gameplays: a) Air Zonk (NTSC/PAL): Minute 35:00 starts final battle and when the player defeats final boss reward is 10 millions of points. b) Air Zonk/PC Denjin (Japan): Minute 31:48 starts final battle and when the player defeats final boss reward is 89 millions of points.
PlasmaBlood played in Japan version while PMniac (surely $imon too) played in NTSC/PAL. Just compare both proofs.
