Sorry but there is no way to play this game on the GP2X. The PC MAME is the only emulator that plays this game and it was in a way later version of MAME. MAME2X is based off of version 0.34 and some of 0.35 I believe. I don't see mame going up passed version 0.36 on the GP2X so I wouldn't hold your breath for playing this on the GP2X. It does suck though because it is a very nice 2D fighting game.
