EDIT: I've tried the 99% patch on the gba emulator on psp using the nes emulator for gba that was mentioned before.
Yes, a psp emulating a gba emulating a famicom, and it works at 100% speed! (well, I don't see any reason why it wouldn't).
Only problem is an anoying "this is only a demo" message that appears while playing...I can't find it in the rom to change it with spaces, it's a pitty since I have a gba cart (and a gba).
You need an emulator that is compatible with the special Chinese mapper. And what do you mean you're not a fan of PC gaming? Can you name any of the great classic PC games from the '90s? Anybody who thinks they're not a fan of PC gaming should try out some of the really great titles like Descent, Broderbund Stunts, One Must Fall, Scorched Earth and the id software collection from Commander Keen to Quake 2. Then you can say whether you're a PC gaming fan or not.
Yes, I already have psp nesterj's v3 with the memory maps needed (too bad the source changes aren't in the package). Also fceux latest version runs the game just fine.
With pc gaming i was referring to playing games on the computer, not the games itself. I've grown up playing computer games (monkey island, pop anybody?) but playing while being on a couch or laying in the bed feels better ^^
