Level bugs

Final Zone Boss Bug

In Final Zone, getting the final hit on Robotnik early in the round will allow a player to hit him again while the piston slowly retracts. This action loops his hit counter from 0 to 255, and interrupts the defeat sequence, making Robotnik restart his attack pattern. The only thing that can be done at this point is to fight on until Time Over or allow yourself to be killed and restart the stage.

Not fixed in any version of Sonic 1 Genesis.

Fall Out Of The Special Stage

Sometimes, you will fall out of the special stage for no reason what-so-ever. It is unknown why this occurs, and since it is a port, meaning none of the beta things were left in, the only way to get out of it is to reset, as there are no glitch emeralds or goal blocks out side of the stage as there were in the original.

Not fixed in any version of Sonic 1 Genesis.
