I have a Rave Racer DX cabinet (the single player one) and I also have the System 22 board-set. The issue is that the board-set that I have is from the dual cabinet version which means no 6-speed shifter, just the up and down one.
I've played around with the Roms in MAME to see if there is a different rom set for the DX versus dual cabinet but haven't had any luck. Just wondering if someone knows how to make the System 22 boardset become a DX cabinet type?
