Recently downloaded this nifty little multi-emulator app for my phone. Main reason was to check out and see if the PlayStation one emulator would run on my older phone. WORKS excellent. Runs insanely smooth, like a brand new game.
This app also has a game boy, game boy color, game boy advance, Nintendo 64, Nintendo (original), Sega CD, Sega Genisis and Neo Geo emulators. Would definitely check out this app if you want a old school nostalgia gaming experience while on the run.
