Did you even LOOK at inoble's posted link to another message here?
A Kouji | Posted 3/4/2008 11:13:33 PM | message detail This game responds badly to codes. Even using a simple code, like infinite money, more or less guarantees that the game is going to corrupt every VP2 save-file on the memory card, making it freeze part-way through Chapter 5.
Exchanging Soul Crushes? That's just asking for it. :\
Yeah, everyone wants codes for this game. Imagine infinite CP or being able to use more sealstones. Unfortunately, the reality is that someone needs to hack some anti-cheat bypass codes so the game doesn't freeze. Rest assured as soon as we find some proper working codes they will be everywhere.
