Omitted Games
Several games were omitted from the final release.

The next was Knuckles' Chaotix, which was removed for unknown reasons, however a whole art section still appears in the final game. The final was Sonic Eraser, which can be found by hacking the game. Four games [mentioned earlier] were omitted to lower the game's ESRB rating.
