In the original Sega CD version of Sonic CD, if the timer reaches 9:50, Amy will be forced to let go of you and will stop trying to hug you, so that you can reach the end of the stage without interruption.

There's dummied out code that exists in Sonic 1 for when Sonic runs into a wall, where it will attempt to stop Sonic in the direction he's moving, and then move him upwards. It works best when he's on the floor, where he will climb up the wall. Otherwise, it's pretty broken.

More Mario content? Oh no! Anyways... so, you know how in Mario 1 on the NES, you bounce downwards when you destroy a brick, but hover upwards in the SNES version? Turns out the SNES behavior was possibly the intended behavior? Here's how it works.

In the original Sega CD version of Sonic CD, after you beat Metal Sonic in Stardust Speedway, there are 2 ways to end the stage. The obvious one is to let Amy hug you. The other is to walk to the left and wait about 10 seconds after freeing her.

In the Nick Arcade prototype of Sonic 2, there lies leftover scraps of a build process for an even earlier build. One of the things that can be found is an earlier version of Emerald Hill's boss. It has only 2 hit points, no hitbox for the drill, and a weird bobbing animation.

Sonic 2's camera is known for lagging behind Sonic when he's moving too quickly. The reason that happens is due to the stage renderer only being able to draw directly where the camera is at, regardless of how far it has moved. Areas that should have been drawn to get skipped.
