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. | 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.

General bugs
Missing Press Start on Title Screen
The text "Press Start Button" was meant to be displayed on the title screen. Due to RAM not being properly cleared after the two previous screens it does not appear. The byte that should call for it to appear is shared with the previous screens and since the RAM in this area is not reset the value is stuck in a no call state. For a more technical explanation check the Sonic Retro forums here.Not fixed in any version
Hidden Points Bug
At the end of the level when jumping to collect the hidden points the game only rewards 10 points for the 100 point flags. A explanation how to fix the bug on your own is available here.
Not fixed in any version
Missing Percussion after Extra Life Music
After collecting an extra life, if you pause the game as the main zone music starts to fade in, when you resume the game, the music resumes fading in but without percussion. Percussion is restored for the next music track that is played. (Completing level, getting invincibility monitor, getting extra life, etc.) Alternatively, this also affects the Special Stage theme, but in a different way. FM channel 6 is disabled because the Special Stage theme uses 6 FM channels, unlike every other song in the game. You don't have to pause the game for this glitch to occur, it occurs after the song fades back in.
Not fixed in any version
Time counter doesn't flash
If the player is in the ninth minute, but he has at least one ring, the TIME counter won't flash red because of a mistake in the HUD code.

Level bugs
See the External Links below for a video about these bugs
Zip through walls in Scrap Brain Zone
On the first act find the ledges that move right then left. Go to the far right side of the wall and wait for the platform to move to the right. As soon as it starts to move right, duck. You'll go through the wall. While here, press to zip right and to zip to the left.
Fixed in Sonic the Hedgehog Genesis
Speed Tunnel Scrolling in Green Hill Zone
On the first act there is a series of two speed tunnels with a star post in the middle. Occasionally, if Sonic is moving too fast the screen won't scroll down fast enough and when Sonic touches the bottom of the screen he will die, as if it were a pit.
Fixed in Sonic the Hedgehog Genesis
Crash game in Labyrinth Zone
At the end of the first two acts, Sonic can fall off the level by rolling after passing the signpost, which may result in an Illegal Instruction exception.
Fixed in Sonic classic collection
Fall off level in Final Zone
It is possible to fall off the edge of the level after defeating Eggman. This is only possible if Eggman is hit one final time when trying to escape. If not, Sonic's forward movement will be stopped when jumping near the edge.
Fixed in Sonic the Hedgehog Genesis
Fall off level at end of game
When Sonic is celebrating victory with the flickies, and the other animals, you have to have debug mode on for this or it won't work, press the B button to turn into something then press the B button again to turn back to Sonic, then run to the beginning (to the right) and jump still pushing the D-Pad to the right and you'll lose a life and the screen'll turn white.
"Not Fixed" in any version
Die in any Zone
Use the debug-level select cheat (up, down, left, right, up, C, C, up, down, left, right, A+start, then hold A until game starts) select any level then press B, and move off the edge of the screen and press B. Sonic will die.
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.
Fixed in Sonic the Hedgehog Genesis
Going too high in Star Light Zone
On the first act there is a place with an Orbinaut. Jumping there is OK, but if you're pushed higher, by getting hit, you'll die.
Fixed in Sonic the Hedgehog Genesis
Player bugs
Jumping next to solid objects
In certain circumstances, but most often when next to a solid object, jumping will use the wrong animation, so that Sonic appears to "walk" in mid-air. This happens often in Marble Zone while on the blocks that float on the lava. This also happens in Green Hill Zone Act Two, at the second block (the one with the yellow spring on top).
Not fixed in any version
