thanks for the heads up on space harrier! that game is awesome. can't believe i never heard of it as a kid. as for more games, definitely check out streets of rage 1, 2, and 3, NBA jam tournament edition, maximum carnage, and joe and mac. i also just noticed the psx emulator and MAME emulator are out. do those work well? i imagine the psx would be pretty slow
SF2 is super laggy on the MAME. NES is ok (ive only played SMBros), and genesis is alright. I probably wont put a lot of games on there, as the screen size is like 1 inch and the controls are a bit buggy.
Gonna have to check out the Genesis emulator, I was addicted to the Sonic and Shinobi series for a long time. ScummVM FTW still, though. Can't beat Indy on the iPhone, and not some Crystal Skull garbage.
