i dumped the move garc with pk3ds to get the 0.bin file.
though i did use garctool first and got the same .wdn file and figured it was just cause garctool is old.
either way i am unsure of how to edit either the bin file/s or the wdn.
but i think the first .bin that pk3ds unpacks is the same thing as that WDn file that garctool unpacks, you can unpack the .WDn file with pk3ds to make the same numbered .bin files that i spoke about before
and my first thought was each of those .bin's must be a move. but when you open them up on notepad++ its unreadable, and if you use HxD you have no idea what move it is(if it is even a move)
EDIT:
trying to do more research and i found this https://github.com/kwsch/pk3DS/issues/189
maybe one of those flags he speaks about is the culprit? i would like to test it but have no idea how he is finding those flags and what program he is using to do the edits and what file he is editing(.bin or .WDn)
