So I coded myself a quick program like yours which randomizes the OW models in the garc 0\2\1 and everything works fine except the player model which is still the same but glitchy. The glitch itself does not worry me but the fact that the model wasn't change while in the garc it was it's kinda strange.
Any ideas of what could be causing this?
Honestly been away from all of this for a while, but there's a list of every garc here:http://pastebin.com/QNCz7Avh
I think OR/AS it's just the world models folder, and then there's also a battle models folder. I wouldn't think they'd differ too much from X/Y, but ya never know. Just experiment, something'll happen.
