Knuckles is the guardian of the place and Sonic and Tails will therefore have a new tough opponent in this 3rd episode. Released in 1994 on Sega Genesis console, here is the version of Sonic 3 coupled with the Sonic & Knuckles cartridge. It contains all zones from these 2 games as well as the ability to play Knuckles in Sonic 3.

Change Identities[edit]
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.
Different Battle Music (Sonic 3[edit]
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.
Extra Rings in Debug Mode (Sonic 3)[edit]
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.
Random Starting Location[edit]
Enter the sound test menu choose a level. Look for a star post, touch it and hold A and press START. Then choose another level. If done correctly the title of the zone will change. Beware you might start out in a wall so use debug mode to fly out.
Level Select (Sonic 3 Only)[edit]
This code requires a Sonic 2 cartridge. Insert Sonic 2 and enter the Sonic 2 Level Select (play sounds 19, 65, 09, and 17). Return to the title screen, hold A and press Start. To transfer this to Sonic 3, hold A and carefully remove the cartridge without turning off the Genesis. Insert Sonic 3 and press Reset. Finally, release A and press Down twice at the main menu.
Note: If you look at the icons, you will see them from Sonic 2. Sometimes, we don’t have Hidden Palace Zone in Sonic 2.
Hyper Sonic[edit]
To become Hyper Sonic without getting all 14 Emeralds, first enable the level select and debug mode. When the game begins, create a power-up box. There should be an 'S' on the box. Jump on it to grab 50 rings and become Hyper Sonic!
Slow Motion[edit]
First enable Level Select. While playing, you can pause the game and press A to restart, B for slow motion, and C for frame advance.
Unlimited Bonus Stages[edit]
Enter the Level Select code, then highlight the '2P Vs' option and press START. You will enter a series of bonus stages that last until you reset the system or press A+START.
View Animations [edit]
Enter Debug Mode and press B + C. You'll be treated to a view of Sonic and Kunckles' moves.
Super Tails (Sonic 3 and Knuckles)[edit]
Enable Level Select, then press Down to make sure you have the sound test (don't select it yet). Start a one-player game and choose Tails in the Data Select screen. When the timer appears, press RESET.<p>
Enter the Sound Test menu and choose any zone. Hold A and press Start. You should be Tails and be in debug mode. From here press B, then press A until you see a box. Press C to select it, then press B to return to Tails.<p>
To enable Super Tails, jump on the box. Tails’ flickes will come. He can still get squashed and drowned, though, so be careful in the Ice Cap zone. You will have do this at the beginning of each zone. Robotnik can bounce him at the very end of Launch Base zone-act 2.
(Sonic 3) Cheat: Secret Special Stage[edit]
For a bonus stage, enable Level Select, then play tune 1F. Finally, highlight stage 2 and hold A while pressing Start.
Play at Night[edit]
Enter the Level Select code, then press C + Start to choose your starting level.
Mecha Sonic and Tails (Sonic 3)[edit]
Use the Debug Mode code in Launch Base act 2. Beat the game. When Sonic or Tails jumps towards you, activate Debug Mode and get out of it immediately. You will be able to use Sonic or Tails in the background for a short time, but they will look like robots.
Extra Lives (Sonic 3)[edit]
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!
Easy Emeralds[edit]
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.<p>
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.
Flashing Super Sonic (Sonic 3)[edit]
Enter the Level Select Code, then enter Debug. Go to Hydrocity Zone Act 2. Turn into a box that says 'S'. Jump on it. When you get to the boss, wait until Sonic twists up to the top, and he will be flashing.
Crystal Boulder[edit]
Start a Game and go to Lava Reef Zone Act 2. You will need to use Debug Mode. Go to Knuckles and go to the top. Sonic will be sent to Act 3 if he goes down.
GAME CRASH[edit]
You will be sent to Sonic 3.
Comments
Sonic 3 Complete is a hack of Sonic 3 & Knuckles. It began primarily as an alteration of the musical configuration of that game to to more closely resemble that of the original Sonic 3. It also contains bugfixes and other additional features, and provides versions of Sonic 3, Sonic & Knuckles and Blue Sphere with these same additions and fixes, essentially providing a console version of Sonic & Knuckles Collection. Additional menu options and ROM patches are available to reverse some of these changes, or make others, to provide a version to match the player's own preference.
Patch is in xDelta format, with other minor patches included in .ips format.
