Are there any new cheats for Sonic 3 and Knuckles

To get level select...
At the first level, go to the first trapeze thing and when on it, hit left left left, right right right, up, up, up. you'll here a ring sound. hit start and hit A to go to the menu. go down 3 times to find level select/sound test. go to the first mushroom hill. go to the first pulley thing that you can hang on and do the same code. go back to level select, hold A while selecting a stage. hit B to change, A to toggle sprite, and X to make the sprite. this code works for EVERYONE. Also, the tv monitor makes sonic become hyper sonic and gives them 50 rings. Tails to super tails, and knuckles to hyper knuckles.
