I know iphone 4s and below are incapable of playing these powerful mame games. But has anyone tried playing any of SNK or CPS2 roms on iphone 5?
There was a time that Mame was available officially on the AppStore. Although I myself don't have many games installed for it, I have it on the iPhone5. No idea on your games, sorry, you'll have to give it a go or try asking here... http://forums.toucharcade.com/showthread.php?t=117763&highlight=iMame
