The Sega screen is different, using the standard Sega screen for many Game Gear titles, and plays no "SEGAAA" chant.

Following the Sega screen is the brief intro sequence, which only features Sonic running. No music plays here, and the sky colour is the same as in the Master System version.

Final game

Sonic's physics are completely different and almost broken. He gains speed instantly and has no momentum on slopes whatsoever. The player also has no air control when falling or launched by a spring.

There are no death planes in bottomless pits yet. Falling into one causes the game to crash, displaying a myriad of corrupted graphics depending on the level and emulator.
