Most notably, this means that using glitches to skip collecting Emeralds in the final game allows the normal level music to play in the boss room.The triggers that set the boss music are also set differently. Reaching the boss room always triggers the boss music, regardless of how many Emeralds you have.Once the portal to the bonus stage is touched, the game immediately jumps to the bonus stage.The game doesn't pause or show any message after collecting all the rings in a level.There are some different or missing messages from the scrolling bar on the top of the screen.Collecting all the Emeralds plays the entirety of the first-revision title screen music rather than just a small segment.Music can erroneously speed up or slow down randomly.

Sonic has slightly better air control in the final game. The pinball physics are almost finalized, but not completely.This mode is glitchy, however, as items may be stuck onscreen and the sound may get muted after exiting debug. Objects are still processed while the game is paused. A free movement mode can be activated by simply pausing the game and moving with the D-Pad.The game simply returns to the Sega screen after the title screen ends.
