Cheats for Sonic the Hedgehog 2

Glitch: Ending

  • All platforms
  • code
After you defeat Death Egg, there will be a slide show with four pictures of Tails, then you see Sonic falling. Debug yourself, and put Sonic at the bottom of the screen. Exit Debug mode. Sonic will get out. The screen returns back to the slide show.

Glitch: Strange graphics

  • All platforms
  • code
Enable debug mode, then on either Aquatic Ruin Zone place six transfer boxes close enough to each other so you can hit them all at the same time. Leaves should now run through the center of the screen and the background should look strange.

Glitch: Yellow Sonic

  • All platforms
  • code
While playing as Super Sonic, fall off the screen. As soon as Sonic dies, press B and return to solid ground. Sonic will remain yellow as long as you have rings, but he will have no powers. To get his powers back, get hit then get 50 more rings and transform.

Glitch: Death Egg Zone

  • All platforms
  • code
Enable the "Level select", "Debug mode", and "Super Sonic" codes. Enter Death Egg Zone. Bring Sonic into the first room, but not all the way. Sonic should still see the hallway behind him. Create two teleport boxes. Create 50 Rings and collect them. Jump on one box and the screen will transport. Move to the right and Sonic will be in the room completely, and Metal Sonic will come down. Jump on the last teleport box and Sonic will revert back in the front of the room. He will once again see the hallway behind him. If Sonic goes past this room he will chase Dr. Robotnik and go into the next room. Sonic can continue down past the room, down the hallway, and reach the end. If Sonic touches the floor of the black background, he will get out. You can also do the following additional things:

Glitch: Tails runs in the background

  • All platforms
  • code
In Aquatic Ruins Act 3 with a second controller, when you defeat the Boss have Tails remain on a pillar. Have Sonic run forward and hit the capsule at the end of the level. Tails will be running in the background.

Glitch: Spin forever

  • All platforms
  • code
In Aquatic Ruin 1, go to the first rising pillar. Do not break it. If you did, go all the way left, then return. Spin Dash to break the pillar. The pillar does not break, but Sonic will still spin.

Glitch: No music

  • All platforms
  • code
Enable the "Debug mode" code. In a water level such as Chemical Plant 2 or Aquatic Ruin, debug yourself when you are in the water. Then, go out of the water but do not revert back to Sonic. Wait until you hear the drowning countdown, then revert back to Sonic. The countdown will continue, and it will soon stop. The music will stop playing. Note: If Sonic returns to the water, the music will return. There are some other things you can do with this glitch. Even if Sonic hits the stars box, the music will still not play. However if Sonic will transform into Super Sonic, the music will begin playing again. If you kept debug mode on when the countdown stops, then revert, then debug, the screen will freeze, but Sonic is able to leave the screen. To return to normal, Sonic has to get out. If Sonic goes to the Boss, the music will play once again. However, if Sonic returns to the water and lets the countdown music start, then gets out, the music will stop playing again. To get water in Aquatic Ruin by the Boss, Sonic must be in the water, until he reaches the far right of the screen. The screen will pull up, and Sonic must go to the top of the screen. The same thing happens by Chemical Plant. Once Sonic defeats the Boss, the music will return as the normal music of the level. However if Sonic goes back into the water, the Boss music will return.

Glitch: Strange ending

  • All platforms
  • code
Enable debug mode and turn into a grounder in World 2 Act 1. Fly across the level and finish. Return to normal form after crossing the flag. The flag will look very strange.

Glitch: Move in background

  • All platforms
  • code
Activate the "Debug mode" code. When Sonic or Super Sonic is skydiving off the Death Egg, turn into an object then turn back. You should be able to move a small distance in the air. When Sonic or Super Sonic flies at the screen, you will be able to move in the background for a small amount of time.

Glitch: Move around during ending sequence:

  • All platforms
  • code
Enabel the "Debug mode", "Level select", and "Super Sonic" codes. On the Death Egg Zone, press B to turn yourself into a object and turn into a ring. Then, make about 70 to 80 rings and turn back into Sonic. Collect the rings. Jump and turn into Super Sonic. Defeat Robo Sonic and Dr.Eggman. Make sure that you are still Super Sonic before you defeat Eggman. If you are not, make more rings because you will run out of the place. Then, a little scene with Tails will start. Sooner or later, you will see Sonic flying next to Tails' plane. Press B and you should see white specks. Turn back into Sonic and you can move around. Also, if you try to lay an object, something will happen and your screen will turn blue. The music will stop and you must reset the game.
