Hello There Guys ^^

I'm trying now to active some code in Valkyrie Profile 2 Game and all i get is a freez screen in 2 case .
1st before the game even start when I use action replay codes , 2nd it freez in the loading saved data .
I heard the game may crash cuz of the cheat but no one mention freezing start .. do I do something wrong ?

I'm using ARMAX and GemeShark2 v4
