Why do the don't codes work?

[OrigamiBushi]

I assume that the ones that make the codes that are tested and put on this site and others work well for the one that
make them.Codes such as max stats don't work well for me.
So why do they work well for others and don't for some,is it the version?I have a code breaker3.0,Gamesahrk pro 3.0 for playstation.

Could be wrong codes, could be wrong version of the game, could be user input. I bet you're talking about FF4 for psx? why didn't you just post in the thread you have already asking to fix codes for the game?
