We could only wish we were playing this right now... maybe...
This game was never completed and/or given a public release.
As a result of this, keep in mind that the developers might have used or deleted some of the content featured here, had the game actually reached store shelves.

SegaSonic Bros. is an arcade puzzle game that features official Sonic recolors long before the conception of DeviantArt. It's also notable for having an early version of the Sonic the Hedgehog 3 Blue Spheres theme as one of the main tracks.

The game went unreleased due to performing poorly during its location test in Japan, but the ROM was eventually found and dumped. A special version of MAME is required due to legal concerns, though an unofficial Genesis port exists.

Unused Sprites

The ROM includes sprites for Sonic's band members, a concept from the development of Sonic the Hedgehog that never ended up being used (though Vector the Crocodile went on to co-star in Knuckles' Chaotix).
