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.
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.
Extra Rings in Debug Mode
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.
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.
Different Battle Music
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.
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.
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!
