What emulator would you suggest exploring after MAME? I grew up in the prime time of coin-on operation, so most of the rest of the system emulations are a bit foreign to me. :unsure:
NeoGeo then.
Also if you haven't tried the various consoles, then you are missing out on some real gaming gems!
NES,SNES and MegaDrive are highly recommended
You have to get Picodrive and GPFCE, those are 2 awesome emulators on GP2X. GNGeo is awesome too, even more so now with the performance boost its being given
