*= Code is made by Tiger21820
**= Code works with ALL Sonic games as well as any prerelease version!
***= Code works with ALL Sonic games (Plus prereleases) up to Sonic the Hedgehog 3!
****= Codes work with Sonic & Knuckles and Sonic & Knuckles locked-on with Sonic 3.

All codes tested and are working, however, I have not tested them with Sonic & Knuckles locked-on with Sonic 2.

Enjoy!
