Save this code; cheat code #'s 2-2 and 2-3 require this code!!

Code 2-2: Super Sonic
Super Sonic is invincible to all attacks, can destroy enemies without a Super Spin Attack, and moves ultra-fast.  (He has a cool color, too.) The catch is, you must retrieve all 7 Chaos Emeralds before you are bestowed with this reward.  But getting all of the Emeralds is HARD!  With this code, forget about trying to get the emeralds--you'll already have them all!

: Go to the Level Select (code 2-1).

  4,1,2,6 (pressing C after each one to play the sounds).
: If this code was entered correctly, you will hear a special sound (fanfare).

: Get at least 50 rings, then jump to become Super Sonic!

Code 2-3: Debug Mode
Lost your rings because of Robotnik's Badniks? Get them back fast with the Edit Mode! Select a ring, place it on the screen a lot of times, and now you have your rings!

: Go to the Level Select (code 2-1).
: Highlight "SOUND TEST".
: Play sound #'s
  1,9,9,2,1,1,2,4 (pressing C after each one to play the sounds).
: If this code was entered correctly, you will hear a ring sound, followed by the music.
: Highlight the level you wish to start on, press A (hold), then press START.

: <during game>
  Button A=change item/character when debug mode is on; jump when off.
  Button B=edit mode on/off
  Button C=place item/character on field when debug mode is on; jump when off.

[How to remember this code?
A little bit of history--The release date of Sonic 2 was 11/24/1992! So the sound numbers above is the release date of the game in the U.S.A.!]

Code 2-4: 14 credits (continues)
So you lost all of your lives to Robotnik. Big deal! With this code, you have 14 continues to get back on Robotnik--and each continue is worth 3 lives--so, if you do the math, you have another 42 lives to terrorize the Doc!

: <in options screen> REGULAR SOUND TEST
: Select sound #'s
  1,1,2,4 (pressing C after each one to play the sounds).
: Highlight "PLAYER SELECT", then press START.

Back to top

For the ultimate game, enter in code #'s  2-1, then 2-2, then 2-3.  When you enter a code, pause the game, then press A to reset the game after you entered Code 2-1.  (Codes are not erased until game is turned off.)  Skip to any level, use the debug mode to make at least 50 rings, then jump to become Super Sonic! How cool is that? Make Robotnik run for his life!

: When you start up the game, the SEGA logo will appear. Get your fingers ready!
: When Sonic races to the logo, just before the main title screen,
  press these buttons quickly: UP, UP, DOWN, DOWN, UP, UP, UP, UP.
: Even if the title screen appears, keep going! Press those buttons as fast as you can.
: If you did this code correctly, you will hear a ring sound.
: Before the title screen goes away, scroll up the menu selections
  until you find "SOUND TEST".
: Press START to go to the Sound Test--and the Level Select!

This code may take some practice, so be patient! If you mess up, press RESET (on MegaDrive/Genesis) or press at the same time A+B+C+START (in Sonic Jam for the Sega Saturn) to reset the game and try again. Here's a hint: Whatever you do while entering the code, DON'T STOP!!
