Cheat Codes

These are cheat codes which can be accessed by inputting button sequences or by various other methods.

Cheat Codes, Sonic & Knuckles Alone

  • Zone Select: While in Mushroom Hill Zone, jump on to one of the hanging platforms, then press Left Left Left Right Right Right Up Up Up A+Start. After being taken back to the title screen, select a character and press A+Start. Keep in mind that Sonic 3 levels are not available and that your character isn't able to go to levels it doesn't normally go to in the run of the game.
  • Debug mode: Contrary to popular belief, there IS a debug mode available for this game. However, you need the Sonic 3 cartridge or ROM to do this. Simply start up Sonic 3 & Knuckles, unlock the level select and debug mode codes for that game and then highlight any level in the Sound Test, hold A, press Start, and release A when Sonic appears. Turn into a monitor, and paste a lot of monitors until you see things start to disappear. Then revert back to Sonic, and spindash into the monitors. The game will crash, and be buggy, if you're lucky. Press Start, and then press A if necessary. If you are lucky, the game will redirect to the Sonic & Knuckles title screen. Choose any character, hold A then press Start. You will be in the level select screen. Highlight any level, hold A, then press Start. Note that if you choose any level before Mushroom Hill Zone, you will go into Mushroom Hill Zone instead.

Cheat Codes, Sonic the Hedgehog 3 Locked-on

  • Zone Select: While in Angel Island Zone, jump on to one of the hanging platforms, then press Left Left Left Right Right Right Up Up Up A+Start. After being taken back to the title screen, select a character and press A+Start.
  • Debug mode: First enter the Level Select code then enter Mushroom hill and grab onto another hanging platform and re-enter the code. Press A+Start to return to the Title screen and then select a level on the Level Select using A+Start.

In-level Functions, all versions

Debug

  • Press A to reverse gravity when in normal mode.
  • Press C+B to cycle through all mapping frames of the character when in normal mode.
  • Press B to toggle normal and debug mode.
    • Press A to advance forward through the debug object list.
    • Press A+C to advance backwards through the debug object list.
    • Press C to place the selected object at the current coordinates.
  • Current coordinates are designated by the top line of hex digits in the HUD.
  • Viewport coordinates are designated by the bottom line of hex digits in the HUD.

Slow-motion/Restart

  • During pause press A to fade to black and restart from the SEGA screen.
  • During pause press and hold B to enable slow-motion (this proceeds at half-speed for as long as the B button is held down).
  • During pause press C to advance one frame.

Game Enhancer Codes

These are cheat codes that can only be used with game enhancer devices. Support for these codes is available in most emulators. Unless a code is explicitly marked as (S&K only) or (S3K only), it will work both when Sonic & Knuckles is being played alone and when Sonic the Hedgehog 3 is locked-on.
