As with the console versions you get unlimited time, a coordinates display, a sprite counter, and invincibility. From there, just select any level and it'll be turned on automatically.

When you load up any of the games, you'll start at the level select screen instead of the Sega logo.
SONIC 3 AND KNUCKLES ROM CODE
Though you can enter the debug menu code in-game, you cannot use any object placement functions as controls are limited to four directions and a single key for jumping. In Sonic & Knuckles, this method must be done on the pulley lifts in Mushroom Hill Zone. The method of unlocking the level select in Sonic 3 & Knuckles apparently works in Sonic 3 alone (a good thing, too, considering it's a lot easier to unlock this way) though debug mode won't be unlocked along with it and you can select any Sonic 3 zone as usual (but not Flying Battery, Mushroom Valley, Sandopolis, or Bonus). Press Alt + R to reset the game and from the title screen press Up to reveal "SOUND TEST" and press Enter.

A ring sound will play if you did it right. Go to Angel Island 1, grab onto a swinging vine, and press Left, Left, Left, Right, Right, Right, Up, Up, Up.
