Sonic the Hedgehog Genesis is a “port” of the original Genesis game to celebrate Sonic's 15th Anniversary. While it looks mostly the same, it also has poorly-remixed music, inferior sound, awful physics, bad collision detection, unstable framerates, and numerous inexcusable glitches. And on top of all that, not only was it released the same day as Sonic '06, it was only released in the US.

On August 30, 2008, a proof-of-concept ROM titled Sonic the Hedgehog GBA was released on Sonic Retro, demonstrating just how badly Sega had dropped the ball with their port. The kicker? It had been made by one person.

Sega themselves look to've been impressed by Stealth's work, as he would later help develop the official 2013 port of the original game, the port of its sequel, and Sonic Mania.

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").
