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
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.
Level Select
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.

You might notice a few levels you haven't seen before, but you can't select
them. Those levels were originally intended for the game, but were pulled in
order to release the game on time.
Mecha Sonic and
Tails
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

Super Sonic
To become Super Sonic without getting all the Chaos Emeralds, first enable the

should be an 'S' on the box. Jump on it to grab 50 rings and become Super Sonic!
Super Tails
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.

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.
To enable Super Tails, jump on
the box. Tails will look weird and can not be hurt or lose any rings. 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 hurt him at the
very end of Launch Base zone-act 2.
