Easter Eggs

Debug Mode

There is a debug mode, but for this to work you'll have to get in the sound test area. In the sound test, put those numbers to their appropriate mode: FM40 PCM12 DA11. When those numbers are in place, hit the start button. If this sequence is set correctly, you should have a pic of Tails, a Jeep and a word from the Staff saying ''See You Next Game.'' Push any button and you shall go back to the main menu screen. Start any game and you will be in debug mode.

Hit the B Button and Sonic will transform into any object/enemy you want to place on the zone. Press C to change the object, and press B to go back into Sonic. The changes however will disappear after you've completed or exit the act.
