Well I finally got around to installing mame on my xbox and it works beautifully! Much better than I had anticipated. The xbox controller has to go though. That thing is awefull for arcade games. I've been playing other emulators like nintendo, colecovision, PS1 and the controls were fine. Of course nintendo and PS1 used similar controls. Maybe I'm just spoiled since I normally play games that required a 4 way stick with a 4 way stick and most of the roms I play tested with were 4 way stick games because thats what I like. I suppose a better test would have been to load up some 270 deg. driving games or games that used analog controls.
Has anyone here interfaced arcade controls to their xbox yet? X-arcades interfaces look interesting and the price isn't so bad untill you factor in the cost of the adapters. Is there anyone else making an interface yet? I know I can hack a gamepad, I was just wondering what other options might be available.
