Frankly download an Action replay disk and install the GC backup launcher. Either way you must convert the coeds to the correct code type for example decrypt the Action replay code run through a program that you can get from gecko codes sight. After they have gone through that you can use them to generate a cheat file whatever that may be. (gct?) you then use the cheat file the same way you cheat using gecko OS for Wii titles. Place the file in the codes folder and load the game through Neogamma making sure ocarina is turned on in the GC settings menu.
