I can however understand if you sent Srb2 onto DRRR, having all the Srb2 characters making races on DRRR maps, mostly because then again, DRRR its a Kart Racing game, althought you would probably have better luck using Kart's maps instead of DRRR, given that Ring Racers sometimes may heavily rely on sudden big horizontal boosts for some things, or a consistent horizontal momentum to make some jumps, which some vanilla chars may not be able to make it in time.
