You can use a Daytona 2 cab. Directly compatible. You just have to swap Drive Bd ROM from D2 to R2. Music Bd same but just needs R2 ROMS. You can also use Super GT. Same Drive Bd but neds ROM swap. Music Bd is different but all connections same. You just need Music Bd for R2 and you are good to go. I suppose Dirt Devils is same as well as D2 if you can find one of those.
