Sonic The Hedgehog 2 Sega Genesis Cheats

In-game reset

Enable the "Level select" code. Then, pause game play and press A. You should see the "Sonic and Miles 'Tails' Prower in..." message before you go to the main menu.

Toggle Tails or Miles

Press Up(3), Down(3), Up at the title screen. A sound will confirm correct code entry. Alternately, press Up(2), Down(2), Up(4).

Extra continues

Enable the "Level select" code. Use the sound test selection on the options screen. Choose sounds 1, 1, 2, and 4 (In that order) and press C after each selection. Highlight the "Player Select" option and press Start.

Level select

Use the sound test selection on the options menu. Choose sounds 19, 65, 9, and 17 (in that order) and press C after each selection. A chime will confirm correct code entry. Press Start. Hold A and press Start when Sonic and Tails appear at the title screen.

Level skip

This trick requires the "Level select" and "Debug mode" codes. Go to any stage and change into an object. Press A until you get to the object before the single ring. It is a strange looking object with a little Robotnik head (a machine where all the creatures appear from if you defeated a Boss). Place about ten in a row. Step on the first one until you see the score counting as if you completed the level. When you see that, step on the other buttons. You will go to the level after the level you were supposed to go to. For example: if you were in the Emerald Hill Act 1 you will now be in Chemical Plant Act 1. You can do this trick in any stage, but not in Dead Zone.

Super Sonic and Tails

Enable the "Level select" code. Use the sound test selection on the options screen. Choose sounds 4, 1, 2 and 6 (in that order) and press C after each selection. Music will confirm correct code entry. Select any starting level and collect 50 rings. Sonic or Tails will turn yellow and can run at super speed, jump twice as far, and become invincible to enemies and spikes. The total number of rings will decrease during super mode. Your character will revert to normal when the ring total reaches zero. Note: Super Sonic or Tails can still drown, be crushed, and fall into bottomless pits.

Better Super Sonic

Enable the "Level select", "Debug", and "Super Sonic" codes. Select a stage with Tails in it. Get over fifty ings, then jump. Create two teleportation boxes, spin, and hit both of them. The screen should flash. You should now be Super Sonic surrounded by stars, but will not be invincible. Get ten or more rings and jump again. Sonic will morph to a better, invincible, Super Sonic.

Super Sonic in Death Egg zone

Enable the "Level select", "Debug", and "Super Sonic" codes. Go to the Death Egg zone and turn yourself into a ring. Multiply yourself until there are 50 or more rings. Collect them and jump to become Super Sonic.

Super Sonic animation

To play the Super Sonic animation repeatedly, enable the "Level Select" code, the "Debug Mode" code, followed by the "Super Sonic" code. Go to any level, and any Act (except the single Act levels -- Death Egg, Sky Chase). Complete the Act with more than 50 rings. As the score begins to add up, press B, turn into an item, then press B again. Sonic will do the animation for turning Super Sonic and then return to normal. Press B followed by B again and he will do the same thing. You can continue to do this as long as the score continues to add up.

White Sonic

Enable the "Super Sonic animation: trick" and pause when Sonic starts to do the animation. If done correctly, he should be white, If not, hold B to enter slow motion until he turns white.

Pink Sonic

Enable the "Level select", "Debug mode", and "Super Sonic" codes. Collect over 50 rings and transform to Super Sonic. Press B to enter debug mode, scroll to the bottom, then press B again to exit debug mode, If done correctly, you should die. Quickly press B again and go to some land. Find something that will take all your rings away (spikes, etc.) and you will turn back to blue Sonic. Collect 50 rings or over and transform, and Sonic will turn pink, then yellow. To see this happen more slowly, repeat the trick and press Start to pause game play. Keep pressing B button to see it in slow motion.

Hyper Sonic

Run forward in Oil Ocean, Act 2 until reaching the green jet springs. Jump on the very last spring and hold Right. Sonic will hit a group of spikes before becoming stuck in the side of the wall. Jump out to transform into Hyper Sonic. In this mode, Sonic can run faster and jump farther than Super Sonic, but is not invincible.

Invisible Sonic

Enable the "Debug mode" code and start the game. Press B during game play to transform into an object. Repeatedly press A until you transform into a big white machine. Paste it several times until about 17 machines are created. After that, hit them. If done correctly, Sonic will be invisible.

Ashura

Enable the "Debug" code. Have Sonic become a waterfall. Place waterfalls in random places on a few screens of the first level and repeat many times. Finally, remain in one place and hold the button to continue creating waterfalls. Turn Sonic into himself again and he should emerge as Ashura, his brother. He resembles Super Sonic but has black around his eyes. Press B to turn him invisible.

Debug mode

Enable the "Level select" code. Use the sound test selection on the options screen. Choose sounds 1, 9, 9, 2, 1, 1, 2, 4 (in that order) and press C after each selection. A chime will confirm correct code entry. Select any starting level, then hold A + Start until game play begins. Screen coordinates will appear instead of a score and the number of objects displayed will appear instead of the time remaining. Use one of the following controller actions to enable the corresponding debug code. Note: This code may only be enabled when playing as Tails alone.

Object transformation
Press B during game play to change Sonic into a game object. Press A to change into a new object. Press C to place an object on the screen. Press B again to revert back to Sonic. Note: The type of object that may be selectable will vary from level to level.

Mega Sonic

Collect fifty rings and jump after becoming Hyper Sonic for even more speed and higher jumps.

Continuous music

Select "Options" at the title screen. At the sound test screen, select each of the following sounds in order and press C after each selection: 1, 9, 9, 2, 1, 1, 2, 4. The music from the Oil Ocean zone will play during the entire game.

No music or sound effects

Select 7F at the sound test ascreen and you will not hear any music or sound effects. To return to normal, reset the Genesis.

Faster sound test options

Go into the options screen, bring up the sound test, then press A. You will go up ten at a time, making it much easier when using the level select code.

Unlimited speed shoes

Begin game play in two player vs. mode and hit as many item boxes as possible until you get the speed shoes. Then, intentionally lose your life while you have them (getting squashed is the easiest way). You will return to the start of the level or the last Star Post that you hit, but you will now have the speed shoes in effect for the rest of the stage.

Super Sonic sign

Get all of the Chaos Emeralds and transform into Super Sonic. Try to have at least fifty rings when you finish the level. After completing the level, run off screen and wait until the end-of-level sign shows Sonic. When it does, transform into Super Sonic. The sign will show Super Sonic for one second, then show blue Sonic again.

Death Egg

While in the Death Egg, defeat the big robot, and enable the "Super Sonic", "Debug" and "Level select" codes. Start running out of the Death Egg. While running out, turn into an object, then back to Sonic. Go back to the robot room, and another robot will be there. The explosions that follow you out will follow you while you fight the robot. You can go back a few times using this technique.

Fiery Defeat in Death Egg

Enable the "Debug mode" code and make sure you can be Super Sonic. Gain enough rings so that you will be Super Sonic for quite some time. Defeat Metal Sonic and chase Robotnik and defeat him. When the Death Egg is exploding, and you are running down the shaft to exit, enter debug mode. Change back and run back inside. Robotnik will return and you can defeat him again, however you will be surrounded by fire. When you defeat him again, you will have twice the amount of fire behind when you run out. Note: when this is going on the game will be very slow and you will not actually see Sonic -- make sure you are still Super Sonic when executing this trick.

Emerald Hill music

To hear the Emerald Hill melody at the title screen, go to sound test selection in the options menu and listen to songs 1, 1, 2 and 4 in order. Then, highlight "Player Select" and press Start. You will hear the Oil Ocean music at the beginning of the first level. Reset the game, and you will hear the Emerald Hill music.

Death Egg Zone: Rings

Enable the "Level select" and "Debug" codes. Go to the Death Egg zone, turn your self into a ring, and press C to multiply yourself. Then, turn back into Sonic and collect the rings. This should keep you from dying for awhile.

Extra lives

Enable the "Debug mode" code and start a game with Sonic and Tails. Press Down + Jump (Spin Dash) then press B to turn into an object. Turn into an enemy and place him on Tails. He will still be Spin Dashing. Your points will soon double and you will get lives every second, or depending how fast, you place the enemy by pressing C. Once you have enough lives, turn back into Sonic by pressing B again. This is much faster than setting the alarm off in Launch Base Zone. Note: This works with any other Sonic game that has debug mode. More compact enemies work better than the larger ones. For example, in Aquatic Ruin, the Fly is much more efficient than the Grounders.

Use Tails as a key

Use the following trick if you are stuck or just want a huge shortcut. Play an adventure with Sonic and Tails. Whenever you find a one-way door (a door that will open from one way but not for the other), walk in the opposite direction of it so that it is just off-screen. The game will not detect the door because it is not on-screen. Make Tails go past the door off-screen with controller two. Then with controller one, move closer to the locked door. It should be open and you should be able to get past it. This could cut off up to three quarters off a long level.
