Instructions
Insert the Action Replay cartridge into the top of your Nintendo DS. Slide the game cartridge into the Action Replay top and turn on your Nintendo DS.
Wait for the "Code Input" screen to load as the game starts. Enter the following code, using your DS pen and the displayed keyboard: "94000130 FCFF0000 B2101D40 00000000 E000B5D4 00000104 0000000A."
Add 65 lines of "00000000" after you have input your initial code. Click on the "Copy and Paste" option to select multiple areas of "00000000" code and paste it to save yourself a lot of time.
Input the code "D2000000" after your 65 lines of "00000000." Add one more line of "00000000" to finish the rest of your code. Press "OK" with your DS pen to begin the game.
Start a new or saved game and check your inventory for the azure flute. Turn off the game and reenter the code, if you were unsuccessful.
