Joe, you're not alone... I've played Road Rash probably 50 times, and have never beat the game to see the ending. If you're using an emulator (or have a PAR), one of these should help: http://www.thegshi.org/?s=bsfree2&sys=3&gid=4796
If you're using real hardware, let me know and I'll see if I can make a Game Genie code that lets you always finish in 1st place.
KnightWarrior, I think those codes are for a TG-16 emulator called Magic Engine.
