Bonus Rounds 
from Anthony LaVorgna Jr. 
To play the bonus rounds at any time, insert any game into your Sonic & Knuckles 
cartridge. When the "No Way" message appears, hold A + B + C and
press Start. If you do this with the original Sonic game you can play the levels 
in order and will be given a password to save your progress. 

Note: In case you're wondering, I've left out the passwords deliberately. There 
are over 32,000 bonus rounds in Sonic & Knuckles. I can't possibly list them
all on the page, nor is there much point to doing so since the levels are nearly 
identical. Thank you. 

Debug Mode when Linked to Sonic 2 
from saxman@shentel.net 
Go to the level select screen and play tunes 1,9,9,4,1,0,1,8 (the date when the 
game was made.) Choose any level, then hold A and press Start to activate
Debug mode. To use it, see the instructions in Sonic the Hedgehog. 

Debug Mode when Linked to Sonic 3 
from Kyle Wightman 
There are two normal ways to get debug mode without a GameShark: 

Method 1: Activate level select and hold A and press Start while selecting any 
stage. 

Method 2: Follow the intructions for the easier method in Sonic 3. 

Note: This trick doesn't work with Tails. 

Easy Emeralds when Linked to Sonic 2 
from Sir John Carr 
Enter the LEVEL SELECT code shown below. Go to "special stage" and get an 
emerald. You will go to Emerald Hill Zone. Pause the game, and press A.
Enter the level select again and return to the special stage. Repeat this 
process until you have all the emeralds. 

Extra Points 
from Pierre Wiltzius 
When the end of act marker comes down, jump and hit it for 100 points. Repeat 
this to get more points. 

Hyper Sonic, Hyper Knuckles or Super Tails 
from Kyle Wightman 
Connect your Sonic & Knuckles cartridge to Sonic 3. Activate the level select 
and debug. When you enter debug mode, create a monitor. It will have an "S"
on it. Jump on it to get 50 rings and become Hyper Sonic, Hyper Knuckles, or 
Super Tails! 

Level Select when Linked to Sonic 2 
from Kulock 
At the title screen, press Up, Up, Up, Down, Down, Down, Left, Right, Left, 
Right. You should hear a ring. Next, press A + Start to enter the Stage
Select screen. This code will remain in effect until you turn off the Genesis.
