Level bugs

Knuckles Image

When the signpost is falling, you can view the Knuckles Image.

Fixed in Sonic & Knuckles.

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 (only accessed by using cheats or glitches) 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

If Sonic, playing alone, reaches the end of Carnival Night Zone Act 1 without dying since the start of the zone, Tails will be heard and then seen suddenly dying after the mini-boss is defeated. After the sign falls and Act 2 begins, Tails will reappear and fall into the stage, but will be unable to move, and must be left behind. Should Sonic manage to also then reach the end of Act 2 still without dying, Tails will be seen dying again after defeating Eggman, and will spawn again on the screen after the "Act 2 completed" messages complete. When moving to enter the cannon, Tails will be crushed against the ledge as the screen is forced to the right.

Presumably, this occurs because after loading Tails for the start of the zone in which he delivers Sonic from the end of the previous zone (Marble Garden), Tails is not properly unloaded until Sonic dies or reaches the next zone (IceCap).

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. This occurs in Sonic 3 alone and Sonic 3 & Knuckles, and Tails is repeatedly hit by bombs; however, in the former, after being hit by a bomb Tails will remain running at the very far left of the screen.

'Fixed' (behaviour altered) 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.

Fixed in Sonic & Knuckles.

Hydrocity Zone Floor Glitch

In the section where you go through a loop that leads to a vertical corkscrew that darts underwater, and is followed by a small tunnel and then a thick blue floor that curves up and then back down, Tails can swim through the blue floor in this area if he jumps as soon as he exits the tunnel and then starts swimming at a 45 degree angle to the hill in the floor. Under the floor is nothing but the eventual bottom of the level. Incidentally spikes were placed under other supposedly inaccessible places of the level, just not here.

Not Fixed in any version.

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.

Fixed in Sonic & Knuckles.

Super Sonic Roll Glitch

If playing as Sonic or Sonic and Tails, becoming Super Sonic and rolling will cause the player to slow down.

Fixed in Sonic & Knuckles.

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 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:

Not fixed in any version.

Flying Battery Music

In Sonic the Hedgehog 3 Standalone, the echo track of Flying Battery Zone's Act 1 music will go off sync after the first loop, and slowly gain drag behind the lead melody. The more times the song loops, the farther the echo track will be from the lead. This level isn't playable in Sonic 3 alone, but the bug still occurs in sound test.

Fixed in Sonic 3 & Knuckles Final

Super Sonic Gets Hurt

In Ice Cap Zone Act 1, by using the Vertical wrap glitch, Super Sonic can gain access to Knuckles' area. While in this area, there are icicle spikes that harm Super Sonic, thus the player loses all of their rings and Super Sonic transforms back into Sonic.

Fixed in Sonic & Knuckles.

Super Sonic Gets Hurt (again)

In Launch Base Zone Act 2, when the final boss slams a Super character against the ground, he can still lose rings.

Fixed in Sonic & Knuckles (the character gently bounces off while making a spring sound).

Super Sonic Sprites Glitch

Let Super Sonic be drawn into the boss' water plume and this will happen.

While fighting the Hydrocity Boss, if you allow Super Sonic to be drawn to the water plume, Super Sonic will lose the custom sprites and will appear as regular Sonic (spikes pointing down instead of up) though the yellow color is retained. Furthermore, once this has happened, defeating the boss will result in Sonic retaining the SuperSonic yellow color even after bursting the robotizing chamber open. The score tally will also appear with Sonic's name in yellow instead of blue.

Fixed in Sonic 3 & Knuckles.

Tails’ Sudden Death

In IceCap Zone, Act 1, Tails will lose a life when going down the first slide past the first star post. This can be avoided if you can enter a Special Stage through the giant gold ring found just above said slide. After a life is lost or after returning from a Special or Bonus Stage, Tails can go down the slide without losing a second life. The bug is caused by the snowboard sequence at the beginning of the act. The game attempts to load it when Tails goes down the slope, which crushes Tails.

Fixed in Sonic 3 & Knuckles.

Act 1 Music Glitch

In IceCap Zone Act 1, returning from a Special Stage or Bonus Stage results in the music from Act 2 playing instead of the one for Act 1. The same occurs in Angel Island Zone Act 1, but only after the mid-boss has set the island on fire; this is because everything beyond this point is actually part of Act 2.

Fixed in Sonic 3 & Knuckles.

Marble Garden Mid-Boss Glitch

It is possible to defeat the mid-boss by using 2 player Tails before it has been activated properly. By stopping Sonic before the screen has been locked for the mid-boss fight, and killing the mid-boss using Tails, the act 2 loading sequence will be out of position and crash the game once the end-of-act sign has landed.

Fixed in Sonic 3 & Knuckles.

Carnival Night boss glitch

It is possible for Graviton Mobile to drop the "ball" into the shaft that was used to get up to the boss fight. This is because the shaft is just to the left of the boss fight area and the ball follows the normal set of physics, so it isn't affected by the screen lock. This uses debug to show what happens.
