Games often have major or minor bugs. My favourite is this one:
SONIC 2 had a nice "feature" that made the game keep the Chaos Emeralds you collected when resetting (not turning the power off and on). I accidentially discovered it when playing on a friend's Megadrive. After resetting start the game via the options menu and all the Chaos Emeralds will remain in your wallet.
P.S.: This bug is even emulated by KEGA fusion, I will post screenshots with Super Sonic dashing through Emerald Hill, if anyone is interested
