Hi, thanks for the reply. Yeah I've tried flipping all the dipswitches, a few of them send it into the config screen, but that's about all I've found. I was wondering if it was changable from Km to Miles on the display, but I guess not. Other thing that seemed stange to me is the "Insert Coins" only shows up on one screen.
No big deal though, I cleaned everything up, changed a failing Pot on one of the wheels, and the game is working great, everyone's been having fun with it. My long term plans are putting 2 old xboxs i have laying around into it and hacking the insides of some xbox steering controllers. I'm gonna piggy back the electronics on the controllers into the arcade wheels, so I don't ruin the original arcade setup, but can flip a switch and play networked xbox racing games as well.
