Sonic Mega Collection

After you've done the Pick Level code/cheat go to the Sound test screen and play sounds 04, 01, 02, 06. Now collect 50 rings and jump to be Super Sonic.

When you become Super Sonic, you achieve Super- jump, Super-speed, Super-spin dash and invincibility. (Note: Super Sonic uses rings, so be careful of your ring total)

After you do the Super Sonic code, (Sonic 2-Super Sonic {Real Way} Cheat), collect 50 rings and jump, (before you do this, use the Sonic 2-Debug Mode cheat), press Start, and tap B repeatedly. You should see Sonic changing colors.

Note #1: Sonic changes in this order: pink, blue, then yellow.
Note #2: If your timing is right, Sonic's colors will change to white on the front and black on the back (before he turns pink in note #1).

First go to Options. Then play these sounds from Sound Test in this order: 19, 65, 9, 17. When the last sound starts you will hear the sound of 'when you collect a ring'. Go back to the Title Screen by pressing Start. Now, when you highlight 1 Player, hold A and press Start. You should go to Level Select. There should be a Sound Test there too. Play these sounds in this order: 4, 1, 2, 6. When Sound 6 starts, instead of hearing the real sound, you'll hear a sound when you collect a Chaos Emerald. Finally pick a level, collect 50 rings and jump to be Super Sonic! {Note this will not work on Sky Chase, the other level using the airplane or playing as Tails.}

As Sonic & Tails, use the Super Sonic & Debug codes and go to any level. Then press B to enter Debug mode and spawn a 'TV thing'. Turn into Super Sonic and hit the 'TV thing'. After the blank screen appears, Tails should be invincible with stars flying around him. When Sonic turns back to normal, Tails' invincibility stars will then have a blue tint. Turn back into Super Sonic and the stars will become white again.

First, use the level select code and go to Doomsday 1 with Knuckles and beat that level and you will see 2 Master Emeraids and more.

Go to the Stage Select screen and hold button B. Then pick a level and start.

As you hear Sega spoken but BEFORE the main menu appears press: Up, Up, Down, Up, Up, Up. Then at the title screen press Up to get Stage select and Sound Test.

Start a game with Sonic and run over to the Madmole near the Super Shoes power-up. Directly to the right of the Madmole is a pulley mechanism that takes you to the next level above by pushing Down on it. Instead of pushing down, push the Left, Left, Left, Right, Right, Right, Up, Up, Up. Now press Start to pause the game and press B. You will be sent back to the main screen. When you can select between Sonic and Knuckles, hold B and press Start for a level select.

Pause the game and hold A for the rest of the stage to play without time passing. Press X to jump and spin dash while holding A. You will move without time passing, but the enimies will still move. To stop the game just relese A.
