Hi, I've been having some issues getting a randomizer to work properly, I decided to randomize it so megas can appear in the wild and it sets it to form 31 which isn't the mega form but form 1 is the mega instead since i tried that and it worked, however when trying to catch a mega charizard Y the game froze and then i battled a random trainer and it froze again halfway through the battle. Is there any way to fix this, I am using an old 3ds system with an older firmware as it is the only thing i have that can play any randomizers.
Help is appreciated, Thanks.
