This article contains a list of glitches from Sonic Classic Collection. Unless otherwise noted, all glitch names are conjectural. Many of them have not been confirmed by Sega.
List of glitches[]
- Game Over distortion:
Sometimes when Knuckles' lives reach 0 in Sonic the Hedgehog 2 & Knuckles, the resulting Game Over screen will appear distorted.
- Background and framerate issues:
When playing as Sonic or Knuckles in Sonic the Hedgehog 2 (& Knuckles), the framerate will slow down and the background will not be able to keep up, and will also flash. This is the only game in Sonic Classic Collection with this issue.
- Running death:
Occasionally, when Knuckles drowns in Chemical Plant Zone Act 2 (if the player doesn't make it in time), Knuckles will die whilst still in his running animation instead of the intended death sprite.
