It is possible to get to a hidden area in Hidden Palace Zone. It is only accessible by using Tails or debug mode. Just before entering the inside of Hidden Palace Zone fly from the two steps left until a ledge is reached. Walk left until six power-up monitors will appear. They will be mostly shield monitors (ring, bubble, fire, lighting). If you run right and jump off at the ledge and keep running right you will find two ring monitors and a 1-up monitor. (In some of the [[:Category:Sonic & Knuckles prereleases|Sonic & Knuckles prototypes]], an "S" monitor is present instead of a speed shoes monitor.)

While in Angel Island Zone, jump on to one of the swinging vines, then press Left Left Left Right Right Right Up Up Up. A Ring sound will confirm correct entry. Press Start, then A to return to the title screen. A new option, "Sound Test", will appear below "Competition". Select that option to go to the Level Select screen.

  • 00 - Sonic & Tails
  • 01 - Sonic
  • 02 - Tails
  • 03 - Knuckles

Debug mode

Enter the Level Select screen, then enter Mushroom Hill Zone. Grab onto a pulley system and press Left Left Left Right Right Right Up Up Up. A Ring sound will confirm correct entry. Press Start then A to return to the title screen. Enter the Level Select, then select a level and press A+Start to start the level with Debug Mode. During gameplay:

  • 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.
  • 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.
  • 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.

Enabling debug mode will disable all restrictions on the level select, allowing the player to use characters normally forbidden from accessing certain levels.

Eighth Special Stages

Sonic3 MD SpecialStage 8 Start.png
SonicandKnuckles MD SpecialStage 8 Start.png

The eighth Special Stages from both Sonic the Hedgehog 3 and Sonic & Knuckles can be accessed in this game. First, enable debug mode (see above), then set the sound test to 07, and press A + Start on the "Special Stage 1" selection to get the eighth Special Stage from Sonic 3, or on the "Special Stage 2" selection to get the eighth Special Stage from Sonic & Knuckles.

Both Special Stages will award a yellow Chaos Emerald and Super Emerald respectively when cleared (whereas the eighth Chaos Emerald was gray in Sonic 3). These Emeralds have no special effect in-game, however, and do not appear on the Special Stage results tally in any form other than a score increase.

Note that setting the sound test to any other value between 00-06 will load their respective Special Stages.

Unused content

Objects

Placeable in edit mode

Description
An "S" monitor. This transforms Sonic, Tails and Knuckles into Hyper Sonic, Super Tails and Hyper Knuckles respectively.
A breakable wall in Angel Island Zone Act 2, which can only be placed with debug mode and is destroyed with a Spin Dash on the ground. A similar object is used as a wall that is opened with a switch. Remains unused from Sonic 3 alone.
A button of unknown purpose. It can be placed in either Act of Carnival Night Zone via debug mode, but it doesn't appear to do anything. Remains unused from Sonic 3 alone.
An unknown Ring-like object that appears to spawn slope collision when placed. It is placeable in Carnival Night Zone. Remains unused from Sonic 3 alone.
A glowing block that can be placed in either Act of IceCap Zone via debug mode. Jumping on it destroys it like the ice blocks. Remains unused from Sonic 3 alone.
A lava stepping stone for the second Act of Lava Reef Zone. Similar objects exist in Act 1, but this unique art for Act 2 is never seen.
A platform for the Glowing Spheres Bonus Stage.
"F" gumball, placeable in Glowing Spheres Bonus Stage. When collected it makes the same noise as a Bumper Ball, but it doesn't do anything.

Others

Description
Some strange platform. It's not placed in any level, but the graphics fit perfectly in both acts of Launch Base Zone. It has no movement on its own when placed and needs specific PAR codes to be entered to do so. To enable it use the PAR code 1EFC52:1200 and it will replace the first ring monitor. From there enter FFF7E0:00FF to make it move down and FFF7E0:0000 to make it return to its original position. The object was found by shobiz, and posted about in
Sonic Retro
this thread.

Extra Data Select Music

If one leaves the game running on the data select screen for about 47 minutes a piece of percussion will be added to the track. A high quality recording can be found here

Sonic 3 Staff Roll Music

The Sonic 3 staff roll music still exists within the game and can be played in the Stage select/Sound test. Simply play #26 to hear it.
