Sonic 3 And Knuckles: Red Sonic and Blue Knuckles
Insert the Sonic The Hedgehog 3 cartridge into the Sonic And Knuckles cartridge and play as Knuckles. Enable the "Debug mode" code. Play until the end with all of the Super/Hyper emeralds. When Sonic, Tails, and Knuckles resting on a giant Sonic 3 and Knuckles logo appears, press B and place an S monitor. Press B again and Knuckles will be blue. Break the monitor, and the Sonic on the logo will turn red and flash white, like Super Knuckles.

Blue Spheres Passwords
Lock-On Sonic 1 or Sonic Classics, at the No Way! screen press A + B + C. The screen will now say ''Get Blue Spheres!''. At the bottom of the screen is a Code Number Password, change it to any of the fallowing passwords and press Start to activate it.
