Hello, have you solved this problem yet? I have same problem here. Whenever i make changes in the overlay using hex editor, encode it and repacked it again then play the game it will always crashed when the battle is about to start (i've just made few changes in the overlay: removing the resistance of steel from ghost & dark). But if i just deccode the overlay and encode it without making any changes then repacked it again, the battle would just start finely. I've used these tools to perform editing: DSBuff, blz and HxD. Can someone help me fix these problem please
