The WIIU's file structure is different but the process is the same. The WIIU's filestructure is actually infinitely easier to deal with. As you've already found, all fighter files are in the fighter's folder. The ACMD files to open are under fighter/[fighter]/script/animcmd/ and the animation file to open with view->parse aimations is under /fighter/[fighter]/motion/body/main.pac
After opening (file) \fighter\fox\script\animcmd\body\game.bin, the human-unfriendly commands pop up. When I open (parse animation) \fighter\fox\motion\body\main.pac, it gives me this error:
"Error reading animation file
: An item with the same key has already been added."
