Glitches

  • Walk through walls

    On levels that allow you to travel upwards or downwards greatly as you progress as Sonic, go to an area where Knuckles' path starts. Hold down and wait for the screen to drop, then jump (do not spindash). If done correctly at a area that will cause this, the screen will shift and scroll in a loop back to you. During this time, you are free to walk through walls. This can also be done in select areas of levels where there is no path for Knuckles.

Secrets

  • Obtain Chaos Emeralds Easier

    Using the level select cheat, scroll down and select "Special Stage". Upon completion on the stage, you will receive a chaos emerald, and begin playing your game on the first stage. At this point, RESET the game via the RESET button on your Genesis, re-enter the level select code, and repeat the process. You will enter the next Special Stage level, and have a chance to earn the 2nd Emerald. You can repeat this process over and over until you have all 6 Chaos Emeralds. However, once you have all six, do NOT reset the system and select a level, or else you will lose them all.

    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.

Glitches

  • Pseudo Super Sonic

    In Oil Ocean Zone, 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). A good place for doing this would be 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.

    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: Joseph Collins.

  • 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.

  • Get Super Sonic on Emerald Hill

    First, you enter the stage select code, shown above. Then you go into the Special Stage in the stage select menu. Every time you finish the special stage press reset and go back to the special stage. Keep doing this until you get the sixth emerald. Then you don't press reset. It will just zap you with your six emeralds into emerald hill. Get the last emerald on Emerald Hill get 50 rings and jump to be super sonic. Be careful to not run out of rings or else you will change into Sonic again. The rings start dissapearing when you are Super sonic.

  • 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.

  • Sonic and Knuckles Mini-Boss Music

    Make your way to the end of Act 1 of Hydrocity Zone (Zone 2). When facing the mini-boss, keep yourself underwater until the water warning music plays. Then jump out of the water.

    The game should now be playing the mini-boss music from Sonic and Knuckles, which wasn't out at the time (the music was evidently included in Sonic 3 to make the backwards compatibility feature easier).

  • Walk Thru Walls

    In the Icecap Zone Act 1, when you come to a wall that only Knuckles can bust through, Hold the Down button until sonic or tails looks down, and the screen pans all the way down. Then Press up and jump at the same time. The screen will start to rotate, walk in the direction of the wall and you will walk right thru it. This only works on Act 1 of The Icecap Zone.
