[dnmodder]

The WUA (ZAR) format is a compressed game format from the creator of Cemu.

WUA/ZAR appears to be more like an archive format (e.g. zip or squashfs) than a compressed disc image format. Adding support for it won't exactly be straightforward, since I'd have to add support for reading individual files from Wii U disc images. (I'll probably do that eventually, sometime...)

Future reference, the meta folder has pretty much all you need other than the icon iirc
