Sonic the Hedgehog Genesis
|Sonic the Hedgehog Genesis|
This game has unused music.
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 did I mention it was released the same day as Sonic '06?
Nearly two years later (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, who then went on to help develop the official 2013 port of the original game along with the port of its sequel and Sonic Mania.
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").
