The Options/Sound Test menus in Sonic 2 and 3 have been removed, and as a result, most Sonic 2 and 3 cheat codes are no longer available. Codes for Sonic 1, Sonic & Knuckles, and Knuckles in Sonic 2 should all be intact, however. =>Code Note: The Genesis A button is Y on the DS, B is A, and C is A.
