General bugs

Moto Bug

Moto Bug isn't a game glitch of any sort, but he is a bug nonetheless, and deserves mention.

Missing Press Start on Title Screen

The text "Press Start" 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

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.

Moving during Score Tally

If Sonic jumps while off the side of the screen before Sonic starts running after touching the end level panel the player will still be able to control him. This produces opportunities to continue grabbing the Hidden point flags.

Level bugs

Teleport 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 Left to teleport right and Right to teleport to the left.

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.

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 slowed when jumping near the edge.

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).
