Select the stage you wish to go to, press START while holding A until the stage begins, and you will have Debug Mode.

B – Toggle Debug On/Off
A – Switch Object
C – Put down the selected object

Press A while the game is paused to reset.

Infinite Lives

First, enable the Debug Mode and Level Select cheats. Then, choose Sonic and Tails as the players.

After entering the codes, choose any stage from the level select menu (preferably Stage 1).

As soon as you can move Sonic, hold down, and press C (don’t let go of down on the D-pad). This will activate Sonic’s spin; Tails will copy the Sonic spin also.

Press the B button and Sonic will become the Debug cursor (Tails will be locked in the sonic spin move).

Press A until you (the debug cursor), display an enemy sprite, like the monkey or that bee robot. Now that the debug cursor displays an enemy sprite, move the debug cursor to where Tails is, and repeatedly tap C.

This will produce enemies where Tails is, and since Tails is locked in the sonic spin move, he will destroy the enemies. As Tails destroys enemies in this position, press C more until the score for destroying an enemy increases from 100 to 8000 to a 1-Up. Once you have enough 1-Ups, press B again to revert to Sonic.
