Please don't cheat. It's no fun playing against someone who has infinite Bullet Bills that travel several times faster than normal ones. Especially when this means that the best anyone else will be able to achieve is 2nd, and that the race will end before they cross the finish line (races end 30 seconds after the winner crosses the line). In SNES Ghost Valley this means for me the race ended before the third lap.
Still, it could be worse. I could be playing Diablo, where using a third-party character editor to create an ubercharacter is a requirement to have a lifespan of more than 5 seconds, due to everyone else creating ubercharacters.
