Sonic Shuffle Cheats

Put your Sonic Shuffle GD-ROM into your computer CD-ROM drive. Go to the folder for Sonic Shuffle. You can then access pictures of characters from Sonic Shuffle, just like Sonic Adventure. There will be pictures of Lumina, Void, and enemies that you fight on the board.

Set your Dreamcast's date to December, 24 of any year. When you play, the character NiGHTS (from the Sega Saturn game with same name) will appear instead of Lumina Flowlight to guide you. However, the voice is still Lumina Flowlight's.

Go to the photo album and select ''Another''. Buy the first picture and Lumina will confirm. Now you'll a toy box in Sonic Room. With this you can play the mini games you already played in Story and Versus modes using any character, including a secret one wich wasn't been unlocked yet.

Complete the whole game once and head to Sonic Room. You'll see the notebook on the table.

Complete the Game once and it will be in Sonic's room. It allows you to change some configuration settings.

Just like the Nights easter egg, you set your date. Instead of Christmas Eve, set the date to April Fool's Day (4.1).
