No way to use them properly or to find a decent tutorial on the Internet. And, of course, support for CodeJunkies wants nothing to do. Unable to recognize the game ... At least I insert a GameBoy Color. In a GameBoy Advance recognizes the game, but the codes do not work, so it's the same. Last thing: this is the version "Pokemon Crystal". YES, it works with many more games (theoretically, if you can you use it ...), it's just aesthetics: the appearance of RA is the same as the cartridge of the above-mentioned game. Well, have fun ... Or not.
