I do know this, there are no glitches on those games (except for emerald) at all, I played them and googled many times on all of them, you can use the GS but save before you use any codes, that would be the safe way to do it, I do it myself every time I load a code on my AR no matter if it says it's safe or not, I just no code since I hatched a bad egg and had to start my diamond game all over because I didn't like having a "?" in my party and yes that's what it looked like in my party!!
