List of unsolved glitches

This article lists glitches whose cause has not been determined.

Glitch	Description	Known Occurrences
TTC Upwarp	The TTC Upwarp glitch caused Mario to teleport from one of the TTC spinning platforms to near the ceiling of the platform above it. The glitch has only been documented one time and may be hardware related.	"TTC Upwarp Highlight" by UncommentatedPannen
TTC Push Block Downwarp	One of the moving bars in TTC suddenly teleported downwards. The warp itself happened off-camera but the moving bar was in the wrong spot after. Since both this and the TTC upwarp involve objects having their Y-position change suddenly, the two may be related in some way. Research is ongoing.	"weird teleporting thing" by dumpdome64
Sound Glitch	Sound glitch is specifically a crash in the audio thread of the game, which will crash the game thread once the two attempt to sync (typically level loading). Most methods of crashing this way unexplained and only recently has the concept of the audio thread crashing become the understood major thing that connects all "sound glitches."

Double Red Coin Sound	This glitch causes the sound for collecting a red coin to play more than once. Although the cause is still unknown, recently IsaacA created a TAS that will sometimes produce the glitch when played back on console. It seems to be nondeterministic, as the TAS does not produce it every time. The glitch does not occur on the US version of the game or on emulator (neither of which it has ever occurred on anyway). Testing on an optimized (-O2) build is ongoing.
