Player bugs

Super Sonic at the end of a level

Attempting to transform into Super Sonic after hitting a signpost or prison capsule results in Sonic "walking" in mid air, and becoming unresponsive to controls. This doesn't cause the game to crash however, as the next level starts as normal after the score tally.

Fixed in: Final revision 02

Tails high score

If Tails hits an enemy after Sonic has just died, he gets stuck and gains a large score (as well as several extra lives). [1]

This bug occurs in all known betas and prototypes; an easy way to reproduce it in the Wai beta is to go to Hidden Palace Zone, immediately spindash to the right, and press jump as Sonic dies.

In the final, Tails starts flying when Sonic dies, making him unable to hit enemies.

Fixed in: Final version

Life counter glitch

If a player dies from time-over in a 2P Versus mode while on their last life, the Game Over routine will be interrupted and the results screen will be displayed. The player who died will appear to have 0 lives, but if they die again, the counter will roll back to "y5" (255), as the lives are stored as an unsigned byte, and the life counter was only meant to display up to 99 lives.

Level bugs

Emerald Hill Zone scrolling

In Emerald Hill Zone, the bottom two rows of foreground pixels don't scroll at all, causing them to be permanently misaligned.

Oil Ocean Zone physics

In Oil Ocean Zone act 2, find the area with four green platforms which launch into the air occasionally. Step on the last one and when being shot out of the the tube hold right and land on the spikes in a way that will knock you into the round object to the left. If done correctly the physics will be different and the character will jump higher. The bug eventually wears off when getting in another speed tube. Alternately you can use this Pro Action Replay code while on that level FFB82C:04. This code only works when reaching that area.
