Go to the options menu from the title screen, and then into the sound test menu from there. Play the following sounds in this order: 19, 65, 09, 17 (if this doesn't work by pressing X, try it pressing square)

After that, press the circle button and then start. You will be taken back to the title screen. When you see Sonic and Miles appear on the screen, press and hold square and press start whilst holding square to be taken to the level select menu.

In this menu, enter the sound test feature, and play the following sounds in this order: 04, 01, 02, 06.

If done right, you will hear a tone, confirming the super Sonic code was done correctly. Click on the level you want to start on, and once you collect of 50 coins in any level, jump. I'm sure you know that while super Sonic, every second you will lose a ring. Once you run out of rings you'll turn back into normal Sonic.

thanx a bunch,super gir!
