Sounds like XBOX is the way to go for newer driving games, but there's a lot of racing games, going all the way back to the early black&white games by Atari. According to the info here on KLOV, there's 332 different driving and racing games, between 1974 and 2006. I was hoping to build an all-in-one cabinet but I guess that's pretty much impossible, so I'd like to focus on all the games that aren't supported on XBOX, esp those that use a spinner-type wheel. I found a program called Mame Compiler 64 that supposedly will let you reconfigure MAME but not being a programmer, I have no idea how to go about modifying MAME to "fix" the driving controls. I'll try contacting minwah about his MAME driver, thanks!
