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.

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.
Information in this section was contributed by DALE GARGIULO.

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.

He resembles Super Sonic but has black around his eyes. Press B to turn him invisible.
Information in this section was contributed by Cody Scholberg.

To get a partly red and green Ashura, do the same thing to get Ashura in Act 2, Emerald Hill. However, stop and go for a couple of times. Then, go all the way back. Press B and you will be a green and red Ashura (look at the life icon).
Information in this section was contributed by Kjtheredbandit.

To choose what color Ashura should appear as, continue to add waterfalls to the screen. Use the extra life Sonic head for reference.

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.
Information in this section was contributed by Jacky Bryant.

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.
Information in this section was contributed by Jeremy Spaulding.

All Chaos Emeralds:
Enable the "Level select" code. Play songs 4, 1, 2, 6, get 50 rings, and jump.
Information in this section was contributed by WVC899.

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.
Information in this section was contributed by Tremor.

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.
Information in this section was contributed by Sonic the Sega Know-It-All.

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: 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.
Information in this section was contributed by Buntyhtr85.

Hint: 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.

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.

You should hear the Oil Ocean music. Then, hold A + Start to return to the Sega screen with the Oil Ocean music still playing.
Information in this section was contributed by Nik98bag and others.

Hint: Emerald Hill music:

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.
Information in this section was contributed by Sonic Maniac.

Hint: Fast Casino Night music:
Enable the "Debug mode" code. Go to Casino Night 1 or 2 with Tails. Find the Super Shoes but do not open it. Change into a coin and give it to Tails until you have 98 rings. Put at least two rings on top of the monitor and at least ten rings in the monitor. Change back into Sonic and hit the Super Shoes. You should hear the extra life music, followed by a very fast Casino Night theme.
Information in this section was contributed by Andy Oh.

Hint: 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.
Information in this section was contributed by Tails "Miles" Prower.

Hint: 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.

Hint: Chemical Plant: Extra lives:
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.
Information in this section was contributed by Pocket Monster Trainer.

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.
Information in this section was contributed by Aceman2000.

Near the end of Chemical Plant, Act 2, Sonic will roll down a hill, and zoom up to collect two columns of rings. This trick will work if he gets high enough and gets on the higher platform. If not, he will fall to the lower path, hit the lamppost, and continue the level normally. After Sonic passes the moving blocks (that resemble four orange square blocks) [Screenshot], there will be two spinning wheels which makes Sonic accelerate quickly. Avoid that. Go a short distance down the path, then run back and jump into the wall. If successful, Sonic will end up in a secret path containing many rings and a life. At the end of the path, Sonic will fall down and end up next to the Boss.

Hint: 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.
Information in this section was contributed by Richard.

Hint: 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.
Information in this section was contributed by Game Wizard.

Hint: Oil Ocean Zone Act 2: Hyper Sonic:
Enable the "Debug mode" code. Enter Oil Ocean Zone. Allow Sonic to go in a balloon. When the balloon shoots out left or right to another balloon, quickly press B to enable Debug mode and go onto a platform. Press B again to return back to Sonic. Sonic will be "Hyper Sonic". This trick works even in Act 1. Moreover, if you enable the "Super Sonic" code and collect 50 Rings, Sonic will be the real Hyper Sonic (being invincible to add it on).

Hint: 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.
Information in this section was contributed by Nik98bag and Christian L.

Hint: Defeating Boss 1:
First, hit him a few times. He will then shoot his drill out of his car. Be careful, as he goes from the side of the screen and also does the drill. Hit him one more time and he is defeated.
Information in this section was contributed by Rjackrill.

Hit any part of the mini-truck (Boss 1). The only part that is close to being hard, is after the hit seven. At hit eight, he will shoot the drill off his mini-truck. Hit him one more time to defeat him.
Information in this section was contributed by Gentlescorpion.

Hint: 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.
Information in this section was contributed by MiraiKid.

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.

Hint: 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.

Hint: 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.
Information in this section was contributed by Knuckles.

Hint: 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.
Information in this section was contributed by Michael Davis.

Hint: 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.
Information in this section was contributed by Mariomaniac64.

Hint: 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.

Hint: Easy level win:
Enable debug mode and create an object that resembles a square made of machinery. Place Sonic above this and drop him.
Information in this section was contributed by DDiMarzo.

Hint: Easy ring capture:
Enable the "Debug mode" code. Make sure you have game set to Sonic and Tails. Go to desired level. Transform into a ring and stop in front of Tails. Keep pressing C, and every ring you create Tails will collect. Note: The maximum amount of rings that can be collected is 999.

Information in this section was contributed by Turbo Tails.

Hint: Shaking level:
Enable the "Debug mode" code. Put two horizontal springs, one in each direction slightly close. In between them, the level will shake.
Information in this section was contributed by Marc Baker.

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.
Information in this section was contributed by DDiMarzo.

Glitch: Move in background:
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.
Information in this section was contributed by Al Saliba.

Glitch: Move around during ending sequence:
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.

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.
Information in this section was contributed by Mewtwo066.

Glitch: Spin forever:
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:
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:
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.
Information in this section was contributed by DDiMarzo.

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.
Information in this section was contributed by Ryanandalyssa.

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.
Information in this section was contributed by Cheathatcher.

Glitch: Death Egg Zone:
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:

Debug yourself to the far right by the black background (one does not have to touch the wall). The robot will slam onto you and hit the air as if it was slamming onto the floor.

Bring Sonic back to the Metal Sonic room (if Metal Sonic is still there). Debug yourself, and the robot will slam into the Metal Sonic room (which makes two Bosses in the same room).

Keep returning to the place where you chase Dr. Robotnik, and you will bring many of the big robots.

Glitch: Ending:
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: Double Boss:
Note: This requires the Virtual Console version of the game. Enable the "Debug mode" code. Activate Debug mode in the Death Egg Zone to phase through the wall that opens when you defeat Metal Sonic. Then, exit and chase Eggman. He will jump into his robot when it appears. It will look like Metal Sonic. To double the Boss, use Debug mode to get to Metal Sonic and wait. Eggman will fly to you and, you can fight both of them.
