Debug Mode
Play sonic 3 locked on sonic & knuckles (sonic 3 & knuckles) do the level select and do the same cheat above (left left left right right right up up up) except its at angel island and you have to swing on the vine to do the level select code.anyway next put the same above (for real on the elevator) let the level select take you to Mushroom Hill.next:go to ice cap zone from the level select and debug your self until you see two crushing floors and one frozen springer and keep pasting hyper blocks by debugging and spindash on them until the game crashes but it might get a little buggy but if it doesn't get buggy press start and the game will turn into sonic & knuckles hold a and press start the game will activate the level select Highlight a level except the special stages while doing that hold A and press start and voila you get debug mode. heres how to work it:b to activate it a to have zero gravity c while activating it paste the sprites a while activating it change sprites.
