Here's some handy cheats to "Sonic the Hedgehog 2".
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.Enable the "Debug mode" code and choose any level except the Death Egg. Press C to cycle through the sprites until you see a glitched-looking prison egg. Return to Sonic again and get him to step on it. The "Sonic got through Act 1/2" message should appear. This will take you to the next level, and even works on Bosses.
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.
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.
Alternatively, enable the "Level select" code. Then, press Start and hold A. Press Start when the title screen appears. Then, play songs 1, 9, 9, 2, 1, 1, 2, 4 to activate debug mode. Then play 3, 4, 1, 2, 6. Create 50 rings in debug mode. Jump, make a item box as Super Sonic, and jump on it. Get hit and change back into Super Sonic.
Enable the "Debug mode" code. Create and position a "Transfer Box" monitor. Hit it while as Super Sonic. You lose all your powers but stay yellow. Tails looks the same but has invincibility, with little stars flashing around him. To regain Super Sonic, allow yourself to get hit, then press B to turn into a ring and place at least 50 rings on Tails. Press B to exit debug mode and jump to become Super Sonic with Super Tails as a follower.
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.
Enable the "Level select", "Debug", and "Super Sonic" codes. Become Hyper Sonic in Ocean Act 2, then collect fifty rings and jump. This will turn you into Ultimate Super Sonic. You will look like the regular Super Sonic, but will be faster than Hyper Sonic and invincible.
In the level select screen, go to the sound test and enable the "All Chaos Emeralds" and "Debug mode" codes. Choose a level with only Sonic in it, then hold A and press Start. Collect fifty rings, jump, and turn into Super Sonic. Wait until your rings are almost all gone. Then, create two teleportation boxes and roll through both. This will make a gold Sonic that has stars around him. He has all of the powers of Super Sonic but will not cost any rings. After this, do not get an invincibility box, this will take away his powers. And if you get more than fifty rings and jump, he will turn into the normal Super Sonic with stars around him.
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.
Mega Sonic:
Collect fifty rings and jump after becoming Hyper Sonic for even more speed and higher jumps.
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.

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.
Easy Chaos Emeralds:
Start the game as usual. Get a Chaos Emerald, reset the game, and start the game from the options menu. You will keep the Emeralds that you have gained so far each time you start from the options menu.
Begin the game with either or both character(s). Collect 50 or more rings and go to the first checkpoint you can find (floating on an island in the air near the Speed Shoes by the tops of the waterfalls). Complete the Chaos Emerald stage, getting (or not getting) the first Emerald. Wait until you can see Sonic standing, then reset the game. On the start screen, press Down(2) to "Options", and select it. Then press Right(2), re-selecting the same character, and press A. Gain 50 rings and go to the same checkpoint. You will be on the next Chaos Emerald stage. Continue to do this until you have all the Chaos Emeralds. If you fail on one, just follow the same procedure to redo that stage.
All Chaos Emeralds:
Enable the "Level select" code. Play songs 4, 1, 2, 6, get 50 rings, and jump.
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.
Hint: 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.
Hint: Starry Super Sonic:
Get all the Chaos Emeralds and collect fifty rings, but do not transform into Super Sonic yet. Find an invincibility monitor and spin (do not jump) into it. Then, transform into Super Sonic. If done correctly, the stars will surround Super Sonic until he runs out of rings and transforms back into blue Sonic. Note: This does not improve Super Sonic's performance.
Hint: Quick Goodies:
At the start of Angel Island, kill the monkey in the tree and jump on the first gray rock to reveal a bumper spring. Bounce up into the tree, and using the bumper spring hidden in the tree, bounce left to land on the moving platform. The platform will take you to a ring bonus and lightning shield power-up. Using the spring in the tree again, bounce right to land on ground with spikes and a RhinoBot. Jump past these to collect the fire shield. When this is collected, Sonic can use the fire dash attack by pressing C(2).
Hint: Bonus Stage (Gum Ball machine):
Enable the "Level Select/Sound Test" codes. If you try to select the "Bonus" option in that screen, you will find that it will not work. Instead, press Start on the third selection down from the "1P vs 2P" options. In Act 2 of that option, you will be taken to the bonus stage. To quit, pause and press Start. Note: After several tries on the bonus stage, the title may glitch and display "DOILUS STAGE" instead of "BONUS STAGE". If you quit after this happens, the sound test menu may go off the screen, and any options that were previously at the bottom of the screen will be at the top, and look out of place.
Hint: Easy special stage:
Collect fifty or more rings to enter the special stage and hit the checkpoint marker.
Hint: 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.
Hint: Mental Sonic:
Enable the "Debug Mode" code. Press B + C during game play. Sonic will go mental, and dash about on the spot, turn upside down, and do other stunts. This can also be done with Tails.
Hint: Bonus points:
For extra points, pass any zone in a certain amount of time. For the best bonus, enter the "Debug mode" code. The clock will stop and you will always score a 50,000 bonus.
Time Points
0:30 50,000
0:45 10,000
1:00 5,000
1:30 4,000
2:00 3,000
3:00 2,000
4:00 1,000
5:00 500
Oil Ocean music:
The following trick allows the Oil Ocean music to be heard during the entire game. Go to sound test selection in the options menu and listen to songs 1, 9, 9, 2, 1, 1, 2, 4 in that order. You should hear the Oil Ocean music. Then, hold A + Start to return to the Sega screen with the Oil Ocean music still playing.
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.
No Boss music:
Enable the "Level select" code and go to a Boss. Press Start then hold B. The game should now be in slow motion. When the Boss enters the screen, hit him, then release B. The game should pause. Press Start and the Boss music will stop.
Super Sonic music when playing as Sonic:
Enable the "Debug", "Level select", and "Super Sonic" codes. Go to Casino Night Zone and turn into Super Sonic. Run into the strange Bumper Bug that you normally cannot destroy to lose all you rings and become regular Sonic. Instead of the Casino Music playing, the Super Sonic music will still be play.
Wing Fortress shortcut:
In Wing Fortress, move with some rings as far to the right as possible without climbing. When blades appear to block your way, hit them. As soon as you are invincible, walk through them. Jump on the platforms to the right and half the level will be completed.
Emerald Hill shortcut:
Insert the Sonic The Hedgehog 2 cartridge into the Sonic And Knuckles cartridge. To quickly get through Emerald Hill 1 and 2, play as Knuckles. Climb as high as you can and glide to the right to reach the end of the level within seconds.
Extra lives in the Chemical Plant:
Insert the Sonic The Hedgehog 2 cartridge into the Sonic And Knuckles cartridge. Play until reaching Chemical Plant Act 1, where you get to the wall with the Spiny Badnik and the warp tube on the floor. Break open the tube and go through it. When you come out you will see a Ring Box next to a tower. Climb up the tower and on the top you will find an extra life. Glide left and you will find another extra life. Glide to the left one more time and you will find yet one more extra life. Since you will not want to go through the level again just glide to the right until you get to the tower you started from. Get on that first tower and glide to the right. The Act will be over and you will have three more lives.
When playing as Knuckles, at Chemical Plant Zone 2, make sure that you have between 90 and 99 rings. When you come to a part with a starpost, a spider, and a 10 rings television, hit the starpost. Then, hit the television. You now have over 100 rings and an extra life. Proceed, and go down to the acid. To the right, should find a 1-Up television. Get it, and jump right. You will eventually die, and have a bonus life. Repeat this process to get 99 lives.
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.
Enable the "Debug mode" code and start a game with Sonic and Tails. Once in any level, turn into any enemy that you can destroy from above. Jump, then enable the "Debug mode" code. Tails should constantly be jumping. Put a lot of enemies underneath him. In about five minutes you will have about 80 to 100 lives, Remember, only put enemies underneath Tails.
Rings in Death Egg Zone:
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.
Green Sonic:
Enable the "Level select" and "Debug mode" codes. Select one of the Emerald Hill zones. When you start the level, press B to turn into a ring. Press A(4) to become four rings in a row going up or down. Then hold C + Right for approximately five seconds. You will return to the beginning. Keep pressing A until you are at the top of a waterfall. You may not see your character, but you still will be there. Hold C + Right for approximately five seconds. Finally press B to turn Sonic green.
Object with cloud:
Enable the "Debug mode" code, then duck and spin. While still spinning, turn into an object. It will still have the dust cloud behind it.
Shielded Tails:
Enable the "Debug mode" code and hit a shield. Place a teleport box down and hit that. Tails will have a permanent shield.
Two Tails:
Enable the "Level select" and "Debug mode" codes. Go to the Sky Chase level. Use debug mode to create a transfer box and break it open. When you hear Sonic die, press B to enter debug mode again. Move the pointer up until you see Tails and exit debug mode. Then, jump to have two Tails.
Play at the end of a level:
Enable the "Debug mode" code. At the end of the first Aquatic Ruins level, press B and change into one of the drill enemies. Place him all over the screen. You must do this before you hit the sign. Hit the Sonic sign and complete the level. Then, press B to change into an object and fly above a drill enemy. Press B again and drop onto an enemy. You will die while your points are being added up, but the game will continue as if you had completed the level. The next screen will say you are in Aquatic Ruin part two, but you will start on the last screen of the first part of that level, and you can play freely in that area until you hit the sign.
Easy level win:
Enable debug mode and create an object that resembles a square made of machinery. Place Sonic above this and drop him.
Fun way to get Emeralds:
Enable the "Debug mode" code and place seven checkpoints in a row. Then, turn yourself into a Ring. Place 50 or more on Tails. Turn back into Sonic. Then, jump in the stars.
Black background and see-through bushes:
Enable the "Level select" code. Choose any level (the first level works best) and begin game play. Press Start, C during game play and the background will turn black and you will be able to see through the bushes you pass.
Shaking level:
Enable the "Debug mode" code. Put two horizontal springs, one in each direction slightly close. In between them, the level will shake.
Glitch: Run in mid-air:
Enable the "Level select" and "Super Sonic" codes, then collect 50 rings in any Boss level. Have over 70 rings after you break the robotisizer (the big capsule at the end of each Boss level). Jump to become Super and run in the air.
Glitch: Tails runs in the background:
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: Strange ending:
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: Strange graphics:
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:
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.
