He looked back at the terminal. The WUX file had changed. A single line of text scrolled at the bottom, written in elegant, looping script that was definitely not part of any file format he knew:
Cuts the file size in half; directly playable in Cemu. Cons: Cannot be easily edited or modded directly. 3. Loadiine / "Raw" Format (RPX/SPL File Folders)
When working with BOTW WUX files, keep the following tips and best practices in mind: botw wux file
Ensure your BOTW WUX file includes the latest update, as WUX files are typically just the base game. 2. The Move to WUA Files
While Cemu runs WUX files perfectly fine, Breath of the Wild heavily relies on game updates and DLCs to run smoothly and access all content.

Technical Report: Breath of the Wild .WUX Files A file for The Legend of Zelda: Breath of the Wild is a compressed Wii U disc image used primarily for emulation. It is a specialized version of the .WUD (Wii U Disc) format, designed to save storage space by stripping out the empty "padding" data found on physical discs. 1. Format Overview and Functionality
To get started, you must first have a file. Because both WUD and WUX formats are encrypted, Cemu requires the correct decryption keys to read the game data. This file contains the "common key" needed for all Wii U games, and you must place it in the correct directory for Cemu to access it.
