Sonic in SMB1

Hack of Super Mario Bros.


A character hack of Super Mario Bros. that replaces the famous plumber with the equally-famous (okay, not really) hedgehog. Features drastic changes made to emulate the Genesis Sonic games.

This hack comes with a secondary patch that restores the original power-up system.

Author’s note: Version 2.5 is finally out! Only the legacy version is currently available, however. The normal version and a bonus hack will be added sometime in the next few days. Until then, enjoy the update!
