Have you heard of it? Apparently, if you beat Sonic R 100%, and tag Super Sonic with Tails Doll, the tails doll will haunt you forever. To get rid of the curse, you have to collect all the time stones in Sonic CD. This only works in the Saturn version, as Miyamoto left a seal in the GameCube version to prevent such a curse. I think this is complete BS. If it was real, then the government would of seized all the copies by now.
