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. 

Different Battle Music 
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. 

Level Select 
from DeepC3603@aol.com 
There are two level select codes for Sonic 3. The second method is easier, but 
requires a copy of Sonic 2. Here's how to do each of them: 

Method 1:
Immediately after the SEGA screen appears, Sonic will charge at you in a ball. 
While he's doing this, quickly press Up, Up, Down, Down, Up, Up, Up,
Up. Timing on this trick is crucial. 

Method 2:
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: You'll notice a few levels you haven't seen before, but you can't select 
them. Since the U.S. version is only 16 megs compared to the Japanese 24-meg
cart, those levels had to go. 

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 
from Pingi Maida Guadalupe (elyu98a@prodigy.com) 
Enter the Level Select code, then press C + Start to choose your starting level. 


Random Starting Location 
Enter the Level Select code and choose a level. Pause the game and press A to 
return to the Level Select menu. Select another level and you will start in a
different area. Beware, for you may start out in a wall. 

Secret Special Stage 
from Sub Zero (sub.zero@mailexcite.com) 
For a bonus stage, enable Level Select, then play tune 1F. Finally, highlight 
stage 2 and hold A while pressing Start. 

Slow Motion 
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. 

Sound Test 
from Tim Barr (tsbarr@hotmail.com) 
Enter Debug Mode, then press Up at the main menu to reveal the Sound Test 
option. 

Super Shortcut in Competition 
from bbayles@geocities.com 
Go to Competition and select Balloon Park. Instead of going forward, fall down 
backward to land on a yellow balloon. Hold LEFT, You should walk on the
ceiling. You will disappear and keep going until you win! 

Super Sonic 
To become Super Sonic without getting all the Chaos 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 Super 
Sonic! 

Super Tails 
from Greg Rozelle (greg@hotmail.com) 
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.

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.

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.
