Level bugs
Random Tails disappearance
Sometimes, Tails won't turn up for the Marble Garden Zone boss, when playing as either Sonic & Tails or Sonic alone. This is currently believed to happen at random.
Not fixed in any version.
Accessing this boss as Knuckles in Sonic 3 and Knuckles will randomly cause the same issue. Another effect that may be related is sometimes you cannot move Tails up and down; that is most likely due to Tails spawning too early, so when EggRobo digs into the ground, stay on the ground and wait for Tails.
Random Tails appearance
Sometimes, at the end of Carnival Night Zone, Act 1, playing as Sonic alone, Tails will suddenly fall from the sky. Unable to move, he must be left behind.
Fixed in Sonic & Knuckles.
Strange Title Cards
By using the level select it is possible to get strange title cards in the bonus stages.
Not fixed in any version.
Strange Pallette
By using the level select it is possible to see Knuckles with strange palettes underwater in various places.
Not fixed in any version.
Super Sonic Bubble Bounce
Super Sonic can perform the bubble shield bounce. This is caused by an error in the code.
Fixed in Sonic & Knuckles.
Angel Island Checkpoint
By using the level select and passing a checkpoint in any zone, then selecting Angel Island Zone (Act 1), the game will freeze. This is because if you get a checkpoint, and pick another zone, the water level will be set to 00. The game can also crash if water covers the whole screen in Angel Island (Act 1), thus making it freeze by this checkpoint glitch.
Not fixed in any version.
Vertical wrap glitch
In Acts where the level wraps vertically, the player can duck, wait for the screen to scroll down, then immediately jump, causing the screen to mistake the player's position and make the screen scroll all the way around. During this time, the player can move through certain objects, including kill planes, allowing access to otherwise restricted areas.
Acts affected:
- Marble Garden Zone Act 1
- IceCap Zone Act 1
- Sandopolis Zone Act 2
- Sky Sanctuary Zone (as Sonic)
Not fixed in any version.
