Sonic the Hedgehog Genesis

Sonic the Hedgehog Genesis is a port of the original Genesis game (albeit using the Sonic Advance engine) to celebrate Sonic's 15th Anniversary. The result looked mostly the same but had poorly-remixed music, inferior sound, awful physics, bad collision detection, unstable frame rates, and numerous inexcusable glitches. Did we mention it was released the same day as this?

Still, there was one good consolation: on August 30, 2008, a proof-of-concept ROM was released on Sonic Retro that showed just how much Sega had dropped the ball. The kicker? It had been made by one person.

Unused Music


Present in the Juke Box is "BGM 19 UNDERWATER 2", which appears to be unused in-game. It's a slightly shorter and reduced-instrumentation version of the used countdown music (listed as "BGM 18 UNDERWATER 1").
