3. Not Yet Universal
Some older emulators or forks (like Decaf) don’t support .wua. And while Cemu handles it perfectly, a few niche homebrew tools still expect the traditional folder structure.
Will .WUA ever be supported on Steam Deck / EmuDeck?
Already is. EmuDeck’s CEMU configuration fully supports .WUA files. Just drop them into the wiiu/roms folder. SteamOS treats .WUA like any other ROM.
Can I convert .WUA back to Loadiine?
Technically, yes, using tools like wua2loadiine, but it is rarely needed. If an emulator fork does not support .wua, you are better off keeping your original decrypted dump as a backup.
