"Codes" Problem & Questions (Dolphin Emulator)

[Dagon-Bloodline]

Hi, could someone teach me how to change the entry code of a character to a No Entry one?

I really want to use Sephiroth (Import-Model, PSA, Texture) by DivineOverlord and some other characters but i need to change the Entry code and i dont know how.

Sorry for noob questions :P
