Has anyone else here played GT4 with a dance mat controller? I raced a BMW M3 GTR on LeMans. Was actually kinda fun hopping around trying to keep the car on the track. I 'modified' the game's controls so the dance mat was UP-upshift, DOWN-downshift, steering left and right, X is accelerator and O was the brake. The very weird thing about this, GT4 doesn't recognize the Dance Mat on the controller selection...but what was even weirder was there was no (BACK) button on the mat, O was X, or (FORWARD) and that really confused me. If you have a sister and she has DDR, and you really want to try this, First plug in a normal controller and go to the race screen, remember I said you can't go backwards on the dance mat.
