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.). 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. In this case, the game need not be paused for the glitch to occur; it occurs after the song fades back in.
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.
When normally attacked, you gain a brief moment of invincibility to get your rings back or destroy the badnik that hit you. However, the spike routines don't check to see if this is true, so if you get hit on a row of spikes, lost your rings, and bounce back onto it, you lose a life straight away. This applies also to shields; so, if you have rings and a shield, the spikes will take your shield, rings, and life one bounce right after another.

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.
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.
At the end of the first two acts, if the camera is panned down at the moment the results screen is about to appear, the game may crash with an Illegal Instruction exception. The SCHG has a fix for this bug.
In Marble Zone, during the sections in which Sonic rides a square rock through lava and there are square walls blocking the way, the player can crouch and go right through the marble walls instead of having to jump over them.
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.
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.
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.
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 whilst on the blocks that float on the lava. This also happens in Green Hill Zone Act 2, at the second block (the one with the yellow spring on top). If you want to fix the " walk in mid-air " bug go here.
At the end of any zone or act with 1 live use Debug mode () when the score counter gets low you should be in the next zone or act with 0 lives
