wux

Documentation

Overview

Package wux implements compression of Nintendo Wii-U disc images. The technique deduplicates the original disc image on a sector-by-sector basis and relies on the fact that despite the disc image being of a fixed size of around 23 GB, the majority of that space will be unused.
