Unlike older formats, you do not need to install keys or put a keys.txt in the Cemu directory. WUA bypasses this entirely.
A file (Wii U Archive) is a compressed format designed specifically for the Cemu emulator (version 1.27.1 or higher). Unlike older formats like WUX or Loadiine (which consists of code , content , and meta folders), a WUA file packs the base game, its latest updates, and all associated DLC into a single, compact, and highly efficient archive.
