Regional Differences
The Japanese version is the same as the final US version, but with the hee-haw sound when dying replaced by a proper jingle. The European version uses a slower version of the hee-haw sound.

The European version is also the same as the final US version, with some music changes: the intro tune was extended, the Options screen music (below) was sped up, and the music of Lava Powerhouse was sped up and bug fixed to prevent the PSG from dying off after the music looped once.

Revisional Differences
The first US release uses the traditional Sonic theme on the title screen and a remix of the Game Over music when a player got Game Over. This version was very quickly replaced by a new version with different, very hastily composed new themes due to copyright reasons.
