Time bonus
You get various bonus points for beating the game in various times - the 2 biggest bonuses are for beating the level under 1 minutes (50 000 points, only possible on Angel Island 1 with Super Sonic without the use of cheats), and the second is for completeing a zone with the timer standing on exactly 9 minutes and 59 seconds (exactly 1 seconds before the timeout kills you - this one is worth 100 000 points).

Sonic & Knuckles Only:

Level Select
On Mushroom Hill, search one of those pull-up thingies. Grab onto them, and press left left left right right right up up up. Should you do it correctly, you will hear a Ring jingle - you can then enter the Level Select/Sound Test menu by pressing A+Start on the title screen. To exit the level select menu, highlight "Sound test" and press start.

Control keys
Once Level Select is activated, you can use these keys: PAUSE, then hit A for soft reset, or B (and hold) for slow motion, or C for frame advance.

with Sonic 3 locked on to Sonic & Knuckles:

Level Select
On Angel Island, grab onto the swinging vines and press left left left right right right up up up. Should you do it correctly, you will hear a Ring jingle - the Options/Level Select option should appear below 2player mode in the main menu. To exit the level select menu, highlight "Sound test" and press start. Alternatively, on Mushroom Hill, search one of those pull-up thingies. Grab onto them, and press left left left right right right up up up.
Notes about the Level Select screen: pressing C will cycle through the available characters, 00 is Sonic & Tails, 01 is Sonic only and 02 is Tails only. 03 is Knuckles. Lava Reef 3 will warp you to the final boss battle in the volcane (endboss of Lava Reef 2). Lava Reef 4 will warp you to Hidden Palace. Sky Sanctuary 2 is Knuckles' version of the zone and Doomsday 2 is the bigass mofo robot endboss with the emerald laser cannon on Death Egg 2. Some levels are not accessable however, like Knuckles or Tails in Doomsday zone (not unless you activate Debug mode), see below.

Control keys
Once Level Select is activated, you can use these keys: PAUSE, then hit A for soft reset, or B (and hold) for slow motion, or C for frame advance.

Debug Mode
Enter the level select cheat on BOTH Angel Island and Mushroom Hill - this will enable Debug Mode. Now enter the stage select and launch the levels with A+Start. You'll be in Debug mode - A flips gravity, B goes into object placement mode (C to place stuff and A to switch to next item, B to exit) and C is normal jump. This also enables you to enter unaccessible stages, such as Knuckles in Doomsday Zone.

Special Stage Select
Once you activated both Debug and Level Select, you can pick which special stage to launch in the level select screen. Set the sound test to any number between 00 to 06 and launch (A+Start) Special Stage 1 with for sonic 3 special stages or Special Stage 2 for sonic & knuckles special stages. Or set it to 07 to run the hidden special stage of both games.

Night Shade mode
Enable Debug mode and enter the levels with C+Start.

Sprite Slide Show
Enter debug mode, then press and hold C, then enter B. Your character will cycle through all of his animations. You can use the frame advance (Pause then hit C) to watch them one by one. Press B to resume control.

Descramble Knuckles and Tails in Doomsday zone
Not really a cheat, but useful nonethless - enter the Debug mode and launch Doomsday with Tails or Knuckles selected. Normally they will be scrambled up. But if you enter the debug object placement once the level launches and exit from it once they transformed, they will be de-scrambled. This may not work on first try though. Addittionally, this will give you a super powered dash on the level, and will scramble Sonic if you use the trick on him.

with Sonic 2 locked on to Sonic & Knuckles:

Level Select/Sound Test
Knuckles in Sonic 2 normally only has a START GAME option similarly to Sonic 1. However, if you press this combination on the start game screen, you will get into the level select menu. The combination is Up, Up, Up, Down, Down, Down, Left, Right, Left, Right. Then launch the game with A+Start.

Debug Mode
Once in the Level Select, go to the Sound Test and play the tracks with B in this order: 01, 09, 09, 04, 01, 00, 01, 08 (1994 october 18, the release date of Sonic & Knuckles). You should hear a jingle. Enter any stage with A+Start to use debug mode.

Night Shade mode
Enable Debug mode and enter the levels with C+Start.

All Emeralds
Once in the Level Select, go to the Sound Test and play the tracks with B in this order: 01, 06, 07, 07, 07, 02, 01, 06. You should hear the Emerald jingle. Now you have all emeralds and can turn into Super Knuckles. Works without Debug Mode.
