Confused Demo
from Simon Jackson
While the demo is playing, hold A + B + C. Sonic will get confused, lose his place, and possibly die.

Control Mode
At the title screen, press Up, C, Down, C, Left, C, Right. While playing, you can pause the game and use A to restart, B for slow motion, and C for frame advance.

Debug Mode
Enable Control Mode. After pressing Start to begin a game, hold A until you see Sonic. If you see a bunch of hex numbers on the top of the screen, you're in Debug Mode.

To start debugging, press B, then you can select any sprite in that level and put it on the screen. To select a different sprite, press A, and to place it on the screen, press C. Note that sprite selection is different from Zone to Zone. Also, instead of displaying the time elapsed, it displays the number of sprites currently on the screen. Control Mode functions work as well.

Note: This only works on the first production releases of Sonic.

Extra Lives
In Green Hill Zone - Act 3, there is a 1-Up at the very bottom of the level. Collect it along with enough rings to make 100 for a second life. Next, grab the 1-Up at the top of the loop-de-loop and die. Repeat until you have enough lives.

Get all Emeralds
This cheat allows you to start at the First Level with all the Emeralds, and with lots of Continues. Use the Level Select cheat (see above) to get to the Special Zone. When you get the Emerald, and have entered into the First Zone, press Reset.

Use the Level Select cheat to get to the Special Zone again. When you get the next Emerald, and have entered the First Zone, press Reset again.

When you have all the Emeralds, continue on with the first level. You get to keep the Emeralds and the Continues accumulated so far.

Level Select
At the title screen, hold A then press Up, Down, Left, Right. When you hear the chime, press Start.

If that doesn't work, try this: at the title screen, press Up, Down, Left, Right, hold A, and press Start. After doing this once, you only need to hold Start + A to enter the level select.

Marble Zone Shortcut
from Ken and Renee Clay (kclay@bellsouth.net)
In Marble Zone act 3 you will find three chandeliers with spikes in them. Go to the far wall (on the right) and jump to the right to find some goodies. Now jump through the wall on the right again, but be careful of the other chandelier.

Scrap Brain Teleport
On the last level (Scrap Brain), find the ledges that move right then left. Go to the left side of the wall and wait for the platform to move. As soon as it starts to move left, duck. You'll go through the wall. While here, press Left to teleport right and Right to teleport to the left.

Secret Special Stages
from Wally singh (alien4king@aol.com)
While using the debug mode, enter any special stage. Turn into any object and travel outside the special stage area. Ou will fall into a secret special stage filled with one-ups and chaos emeralds.

Debug Mode
To enter Debug Mode, play these sounds from the level select screen: 1, 9, 9, 2, 1, 1, 2, 4. Press Start and hold A.

To start debugging, press B, then you can select any sprite in that level and put it on the screen. To select a different sprite, press A, and to place it on the screen, press C. Note that sprite selection is different from Zone to Zone. Also, instead of displaying the time elapsed, it displays the number of sprites currently on the screen.

Easy Chaos Emeralds
Start the game as you normally would. Get a Chaos Emerald, reset the game, and start the game from the options menu. You will keep the emeralds you have gained so far each time you start from the options menu.

Emerald Hill Shortcut
To breeze through Emerald Hill 1 and 2, connect Sonic & Knuckles with Sonic 2 and play as Knuckles. Climb as high as you can and glide to the right. You'll reach the end of the level in seconds!

Extra Lives in the Chemical Plant
from Reptile Raptor (mturza@ix.netcom.com)
If you have Sonic & Knuckles, hook it onto Sonic 2. Play until Chemical Plant Act 1. When 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 one 1-up. Glide left and you will find another 1-up. Glide to the left one more time and you will find yet one more 1-up. Since you won't 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 3 lives more that how much you started the act with.

  WITH CODES 44 THRU 57, THE COUNTER DOESN'T
  SHOW THE EXTRA RINGS, BUT YOU DO GET THEM

SBJA-HJWJ/SBJA-HJV2     Rings worth 2 in special stages--Sonic
SBJA-HNWJ/SBJA-HNV2     Rings worth 3 in special stages--Sonic
SBJA-HTWJ/SBJA-HTV2     Rings worth 4 in special stages--Sonic
SBJA-HYWJ/SBJA-HYV2     Rings worth 5 in special stages--Sonic
SBJA-H2WJ/SBJA-H2V2     Rings worth 6 in special stages--Sonic
SBJA-H6WJ/SBJA-H6V2     Rings worth 7 in special stages--Sonic
SBJA-HAWJ/SBJA-HAV2     Rings worth 8 in special stages--Sonic

SBJA-HAWR/SBJA-HAV8     Rings worth 8 in special stages--Tails

Codes 1 THRU 16 also work for Tails in a one-player game. There is only one total for Sonic's rings in a one-player game. Normally, you have to grab all seven chaos emeralds, get at least 50 rings, and jump to turn into Super Sonic (and be invincible). But by choosing from among Codes 58 thru 64 and 65 thru 69, you can reduce the number of emeralds and rings you have to get. With Code 70, you won't lose your rings with time and drop back down to regular Sonic.

To help you become Super Sonic on the last level, where there are normally no rings, Codes 58, 65 and 72 will do the trick--just jump. Finally, access the level select menu with Code 71.

Alternative Codes: Use these if the first set didn't work.

Green Sonic Glitch
from chris m.t. (ytrp@hotmail.com)
To get green sonic you must enter the level select and debug code. Then you must choose one of the emerald hill zone levels because the code only works in emerald hill zone (1 or 2.) When you start the level press B, you will be a ring,then press a four times,you will be four rings in a row going up or down,you then hold c and right for about 5 seconds,then you go back to the begining, keep pressing a until your the top of a waterfall. You may not see yourself but you're there. Now do the same thing as before, hold c and right for about five seconds. Then press b and you'll be green.

Level Select
From the main screen, select Options. Select Sound Select and play sounds 19, 65, 9, 17, then push C. Press Start to return to the main screen, and when Sonic and Tails appear, hold A and press Start.

More Continues
First enable the level select. Then, at the options screen, play these sounds in this order: 1, 1, 2, 4. Now move the highlight to the "Player Select" field of the options screen and press Start.

Oil Ocean Music
from Roadkill! (roadkill6@hotmail.com)
Here's a way to play the Oil Ocean music through the whole game. Go to the OPTIONS screen and enter sounds 1, 9, 9, 2, 1, 1, 2, 4. You should hear the Oil Ocean music. Next, hold A + Start and you should return to the SEGA screen with the Oil Ocean music still playing.

Play at Night
To play at night, enter the Debug code, then hold C and press Start to begin a level.

Shielded Tails
from The Code Wizard (the_code_wizard@hotmail.com)
To give tails a sheild, enter debug mode and hit a shield. Then place a teleport box down and hit that. Now tails has a permenant sheild.

Slow Motion
First enable Level Select. While playing, you can pause the game and use A to restart, B for slow motion, and C for frame advance.

Super Sonic
To become Super Sonic without getting all the Chaos Emeralds, first enable the level select. At the level select menu, go to the sound test item, and play sounds in this order: 4, 1, 2, 6. You should hear the music you get when you win a chaos emerald. Now select any level, get 50 rings, and jump.

Super Tails
While in Debug Mode, create and position a "Transfer Box" monitor. When you hit it and you are Super Sonic, you lose all your powers but stay yellow. Tails looks the same but has invincibility (little stars flashing around him.)

To regain Super Sonic, let yourself get hit, then turn into a ring (press B) and place at least 50 rings on Tails. Exit debug mode (press B) and jump to become Super Sonic with Super Tails as a follower.

Tails/Miles Mode
from Bo Bayles and sybrgoku@rocketmail.com
At the title screen press Up, Up, Up, Down, Down, Down, Up or Up, Up, Down, Down, Up, Up, Up, Up. A chime will sound and Tails will be called Miles or vice versa.

from Bo Bayles (bbayles@geocities.com)
Enter the level select and debug codes, then go to the Sky Chase level. Using debug mode, create a transfer box and break it open. When you hear Sonic die press B to enter debug mode again. Move the cursor up until you see Tails and exit debug mode. To finish, jump and you'll have two Tails.

Wing Fortress Shortcut
In Wing Fortress, go as far as you can to the right without climbing. Make sure you have some rings. When you see blades blocking your way, go ahead and hit them. As soon as you are invincible, walk through them. Jump on the platforms to the right and half the level will be finished.

Change Identities
from The Code Wizard
Use the debug mode cheat. Start any level that has a special stage ring. Next turn into your favorite object. As an object go to the center of a ring. Now hit B twice quickly. When you get out of the special stage you will look like that object for the rest of the level.

Debug Mode
from Tim Barr and Garrett Hogg
Enter the Level Select code, then press A + Start to choose your starting level. Once the action starts, press C to create an item, B to toggle between items, and A to select items. Alternatively, turn on the Genesis and press Up, Up, Down, Down, Up, Up Up before Sonic gets fully on screen.

If those methods don't work, try this. First you must have Sonic 2. Hook it up and put in the level select code, then put in the debug code and press START. When the screen with Sonic & Tails (Miles) pull out the game but DON'T turn it off and plug in Sonic 3. Now hold Up + A and press RESET.

When the main screen comes up press DOWN three times and you should see sound test go there hilight the level you want and hold A and press start. Now while playing press B turn into a sprite press A to change and C to paste it.

from Tony (rzor1@aol.com)
Just before Before you fight Robotnik in the Hydrocity Zone, act 2, the boss music will come. Keep Sonic's head under the shallow water until he is about to drown, then pop out of the water. You will hear the boss music from Sonic and Knuckles.

Easy Emeralds
from Pingi Guadalupe and LilChango1@aol.com
To gain all the chaos emeralds, enter the Level Select code, then highlight "Special Stage" and press C + Start. After receiving the emerald, press A + Start and repeat the process until you have them all.

Alternatively, enter the Sound Test code and play sounds 2, 4, 5, 6 in order. If you did it correctly, the Emerald sound will play.

Extra Lives
To do this trick you must get to the first level of the Launch Base Zone. Set off the first alarm, stop Sonic in the middle of it, and do a Spin-Dash attack. The flybots will continue to attack, and eventually their value will increase to 10,000 points! Every five flybots will gain you a life and, if you're patient enough, you can earn up to 99 lives!

Extra Rings in Debug Mode
from swalter@silo.com
Enter Debug Mode then select a stage. Next press B, A (you must have Sonic and Tails on-screen.) When your cursor changes into a ring, paste it on Tails. Repeat this process and you can gain up to 900 rings and several 1-ups.

Bonus Rounds

To play the bonus rounds at any time, insert any game into your Sonic & Knuckles cartridge. When the "No Way" message appears, hold A + B + C and press Start. If you do this with the original Sonic game you can play the levels in order and will be given a password to save your progress.

Note: In case you're wondering, I've left out the passwords deliberately. There are over 32,000 bonus rounds in Sonic & Knuckles. I can't possibly list them all on the page, nor is there much point to doing so since the levels are nearly identical. Thank you.
