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.
Accessing this boss as Knuckles in Sonic 3 & 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.
Not fixed in any version.
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.
Tails End-of-level Sequence Bug
At the end of Angel Island Zone Act 2, playing as Sonic and Tails, you are chased by Robotnik's "Flying Fortress", which drops bombs that are easily avoided simply by running at full speed. Tails however will catch up with Sonic and then slow down to avoid overtaking Sonic, and will therefore be caught by the bombs. When hit by a bomb, tails will be dragged along on the left of the screen by Sonic, repeatedly being hit by bombs.
Fixed in Sonic 3 & Knuckles.
Strange Title Cards
By using the level select it is possible to get strange title cards in the bonus stages.
Fixed in Sonic & Knuckles.
Strange Palette
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.
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.
Fixed in Sonic & Knuckles.
Hydrocity Zone Act 2 Boss Bug
After being swept through the tunnel into the cavern to face Robotnik in Hydrocity Zone Act 2, it is possible to skip the boss by running quickly through the area to the right, where the animal capsule can be found and activated. The end of level music will play, and the points added up, but the bomb drop and blast sounds can still be heard from the boss, and the water spout will not appear to take Sonic and Tails to Marble Garden Zone. If the console is reset however, the save game will allow you to continue from Marble Garden Zone Act 1 as normal.
Not aware of fix in any version (Version played: UK).
Hydrocity Zone Ramp Glitch
When travelling around Hydrocity Zone Acts 1 or 2, after rolling at speed up a 90 degree ramp transfer from floor to wall, the player character will sometime glitch inside the wall. It seems to happen more often if the character is rolling rather than running, and if the player is holding "down" on the controller during the roll.
Not aware of fix in any version (Version played: UK).
Super Sonic Roll Glitch
If playing as Sonic or Sonic and Tails, becoming Super Sonic and rolling will cause the player to slow down.
Not aware of fix in any version (Version played: UK).
Super Sonic Elevator Glitch
When playing as Super Sonic in Launch Base Zone Act 1, if the player holds left whilst Super Sonic is inside a "spinning elevator", he will glitch outside the elevator in the "push" pose before the doors of the elevator open.
Not aware of fix in any version (Version played: UK).
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 Act 1
Not fixed in any version.
