Wua Roms Wii U Guide
If you are a data hoarder or a Cemu emulator user, you have likely encountered the old mess: Loadiine, RPX, H3, and encrypted WUDs. The arrival of the WUA format has turned that chaos into a single, elegant file. WUA stands for Wii U Archive . It is an open, lossless, containerized format designed specifically to replace the fragmented mess of traditional Wii U disc dumps.

Loadiine formats—which extracted the files to a folder—were easier to mod but suffered from slow loading times and broken compatibility.
For gamers on the Steam Deck, WUA has been a revelation. Given the Deck's limited storage space, the ability to keep Mario Kart 8 or Super Smash Bros. for Wii U in a compressed, single-file format leaves more room for other AAA titles.
