Code Entry
Power on the Game Boy Advanced system and wait for the main menu screen to load. There is no specific cheat menu, the codes are loaded right here. Make sure you type in the codes within a minute or a "DEMO" mode will appear and you will have to do the codes again. When a code is entered properly you will hear a short sound effect to confirm it.
Unlimited Energy Mode
Receive unlimited energy when you type "B" twice, "L," "R," "Up," "Down," "Up," "Left" and "Right." The energy bar at the top of the screen will never diminish and you can get through levels a lot faster without collecting the energy icons. Reenter this code every time you restart the game.
Costume Mode
Select from various costumes for Raven with the "Costume Mode." Enter "Left," "Right," "Up," "Down," "B" three times, "Up" and "Down" to complete the code. At the start of the game go to "Raven's Closet" and select from a dozen different costumes. Re apply this code every time you start the game to activate it.
Versions
These codes work when using any version of the Game Boy that accepts the cartridge. Just follow the same instructions. These codes also work on emulator versions of "That's So Raven 2: Supernatural Style."
