  7. Infinite Lives

    First, enable the level select cheat and the debug mode which are available here. For this to work, you must choose Sonic and Tails as the players.

    After entering the codes, choose any stage from the level select menu(preferrably 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), displays 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 1up. Once you have enough 1ups, press B again to revert to Sonic.

    This enables the Debug code, you should hear a ring chime if the code is entered correctly. start the selected level with A+start.
    To get all 7 Chaos Emeralds, input this code the same way:
    01 06 07 07 07 02 01 06
    You should hear the Emerald chime. note: this code may not work without the Debug code

  10. 14 Continues

    Go to the sound test (not the one on the level select) and put in 19, 65, 09, 17, 01, 01, 02, 04 (press A after each one). There won't be a confirmation sound. Start the game by pressing Start on the first option (character select) and you should have 14 continues.

    Contributed by: Ant P 

  11. All 7 Chaos Emeralds

    This code only works for Sonic. First, do the Level Select cheat. In the Level Select menu, go to Sound Test and hear the sounds 04, 01, 02, 06 in this order. If done correctly, you'll hear a Chao Emerald sound effect. Now, select any stage from this menu and not only you'll be able to turn into Super Sonic with 50 rings but also you'll get Sonic's second ending after beating Death Egg Zone.

  12. Super TAILS

    Normally, when you turn into super sonic you lose tails behind you all the time.

    Well, after you put in the debug cheat and have started a level (preferrably Emerald Hill), turn yourself into a box and place it somewhere on the floor WHILE you are super sonic. It should be a switch places box. Hit it and you will see tails will have a permanent invincible circle around him. He will stay like this through the whole level, he will keep up with super sonic or even out run him. A very fun glitch for 2 players.

    Contributed by: OriginalCheatFi 

  13. Alternate Debug

    Enter at soundtest ''19, 65, 09, 17'', then press A + start, then when sonic and tails pop up, press A + Start to go to the level select screen. On the sound test area, enter ''01 09 09 02 01 01 02 04'' and then press A + Start. This is an alternate debug to the others.

    Contributed by: Topchris 

  14. Pseudo Super Sonic

    In Oil Ocean Zone Act 2, if you manage to take a hit and end up landing in one of those green-and-gold checkered cannons, you'll fall right out, but you'll be moving at twice your normal speed as well as jumping twice your normal height(with twice as much gravity). In Oil Ocean Zone, Act 2, near the first set of pop-tops and cannons. Just jump into the semi-hidden bed of spikes on the right and land in the cannon.<p />Note: Moving at twice normal velocity can often get you stuck in a wall. Also, this wears off if you Super Spin Dash or Spin Dash. It also only lasts for that Act.

    Contributed by: JosephLithius 

  15. Becoming Super Sonic in Emerald Hill - an alternate way

    For all those who like to play honest instead of cheating all those Chaos Emeralds together, there's an alternate - yet simple - way to become Super Sonic in Emerald Hill Zone 1. It involves some serious work, however:

    1. Complete the special stages as you would usually do and collect as many emeralds as you want.
    2. Press RESET.
    3. Start a new game USING THE OPTIONS MENU! This is crucial! Otherwise your emeralds are gone for good!
    4. Continue collecting the emeralds, if you don't have them all, yet and repeat point two and three until you got them all.

    If you did everything correctly, after your last reset you should have all the emeralds from the very beginning and without using any code ever thus making Super Sonic available from the very beginning.

    This has been tested and confirmed with the PAL version of Sonic 2 playing on a PAL Megadrive II.

  16. Better luck with slots

    In Casino Night Zone, you’ll find a few slot machines. Hold A while in a slot machine and 9 times out of 10 you’ll get 3 matching symbols.

    Contributed by: -_-_fa4 

  17. Aquatic Ruin Raft

    When you start Aquatic Ruin Zone 2, you'll encounter a couple of platforms that swing left and right over the water. When you reach the second platform, don't jump off it when it swings right. Instead, stay still on top of it. The platform will detach from its chain and land in the water, functioning as a raft and allowing you to float over a section of the stage without you falling in and risking drowning.

    Contributed by: discoinferno84 

  18. Slow Motion

    Weird trick, but you can play this game in slow motion. First, enter the level select code, found somewhere in the list of all other codes. Then start your game in any level. When you start, press pause. Then hold down B button and try to do anything with Sonic. The game will play in slow motion as long as you hold down the B button.

    Effect Effect
    Level Select, Pause, hold B Causes the game to play in slow motion.

  19. Silent Mode
