Harry Potter and the Chamber of Secrets is a game that follows the events of the second Harry Potter book.

Cheat Menu

The game has a hidden debug cheat menu with lots of different features. Use this codebreaker code to open it instead of the main menu: 02002642:16. Don't forget to disable the code once you opened this menu. Now this menu will be opened instead of the main menu until you restart the game. There's also a legitimate way to open this menu. Go to Flying Practice and select any challenge you didn't get the card for. Finish the challenge and get the card, but when you see the card press R and you'll open the level select menu, however it won't work yet. Quit the game to get back to this level select menu, but then it will work and by pressing the B button you'll be able to get to the cheat menu itself.

You can unlock all cards, spells and get all beans with some of the options in the list. Option "Clear EEPROM" also seem to erase your save file. But there's plenty of other interesting options in the menu.

Map/Level Select

Hmmm...
To do:
Check if there are unused maps.

From the cheat menu you can open any map in the game and replay Harry's adventures. You'll have all the required items to progress through the game no matter what map or level you choose.

Language Test

Some weird menu called "Language Test" has only some text lines from the intro of the game. You can change them by pressing R and L buttons.

Audio Test

Hmmm...
To do:
Check if there are unused sounds or music tracks.

There's a menu that allows you to listen to every music and sound from the game. There are 80 music pieces and 193 sounds. Change them with your control pad and press R to play the sound or music track.
