Death Egg Zone

• The player does not run in at the beginning.
• The overscan border color for Act 1 is red, instead of black like the other zones.
• There are a few object layout differences, with notable ones being the absence of rings and monitors in some bonus rooms.
• Many sound effects are missing, and the missile launchers play a different sound when firing.
• Red Eye's pillar overlaps the player and has tile transparency issues.
• The explosions seen when Red Eye moves to phase two last longer than usual.
• Red Eye's laser overlaps the floor.

• The palette changes too soon when transitioning to Act 2. In Sonic & Knuckles 0525 and later, the palette is changed after the Act 2 transition completes.
• If the signpost has been hit before landing, it'll fall at an angle when the floor explodes during the Act 2 transition.
• Tails has an animation error during the Act 2 transition.
• Act 2 ends with a Prison Egg after the Act 2 miniboss is defeated, then the player moves on to The Doomsday Zone, regardless of whether or not they have all of the Chaos Emeralds.
