Looking for a Codebreaker file thing-go

So, there is this game cheat device like a Gameshark thats called a Codebreaker for the DC. Anyway, it is superior to the Gameshark except for one thing. It won't work with backups unless you use a special file to boot it with. If you have this file, know where I can find it or at least know the name of it please tell me. Either here or ICQ or Email. Thanks
