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. 

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. 

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

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. 

Two Tails 
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.
