Codebreaker with PSOv2 and GDEmu?

[DreamState]

How exactly is this done? I have the Codebreaker CDI in GDMenu and it takes me to where I can input codes etc.

But, upon doing the VMU swap trick before startup and loading PSOv2 no codes work at all. Am I doing something wrong?

To be clear, I DO NOT wish to cheat whilst online! I am looking to get some cheats up and running on my girlfriends character for personal offline use! Thanks for any help you can give!
