WudCompress is available on the cemu-project GitHub repository and is also distributed via community repositories like the Linux Arch User Repository (AUR) .
Reading the data requires no electricity. A low-powered laser scanner maps the wafer’s annular rings (each ring is a directory), and a companion algorithm— XylDecoder —reconstructs the original files with zero loss. Unlike magnetic tape or SSDs, WudCompress wafers are immune to EMPs, moisture-resistant, and have a projected lifespan of over 2,000 years at room temperature.
Uncompressed Wii U game backups, known as .wud (Wii U Disc) files, are fixed at roughly 23.3 GB, regardless of how much actual data they contain. A game like Super Smash Bros. may take up the full space despite only needing a fraction of it for game assets.
The space savings are immense, as shown in the baseline performance examples below: Game Title Original WUD Size Compressed WUX Size Space Saved Super Mario 3D World 2.61 GB ~88% Space Saved Super Smash Bros. for Wii U 25.0 GB 12.1 GB ~50% Space Saved The Legend of Zelda: Wind Waker HD 23.3 GB 1.8 GB ~92% Space Saved Step-by-Step Guide: How to Use WudCompress
Once completed, a new .wux file will appear in the directory. You can safely delete or archive the original heavy .wud asset. Method 2: Via Windows Command Prompt (CLI)
Code optimizations focus on foundational simplicity over multi-core rendering, resulting in noticeably long processing queues for 20+ GB source dumps. Alternatives for Game Modification and Parsing
Runs as a portable console application requiring zero software installation or external background dependencies.
Unlike .wux , which only compresses the base game, .wua combines the game, its updates, and all DLC into a single compressed file. This eliminates the need for complex virtual file system (VFS) folder structures and makes library management significantly easier. 4.

It began small. Mrs. Hale’s sewing basket swelled until thread rolls resembled tree trunks. The library’s newest donation arrived three times the size listed on the card, books bulging like overstuffed pillows. Roads buckled under the sudden largeness of ordinary objects—benches expanded to couches, mailbox flags swelled into sails. People adapted for a day, then a week, then a weary year. Storage became mythic; closets vanished behind mountains of magnified mugs.
When physical Wii U game discs are dumped for archiving or emulation, the resulting file is a raw byte-for-byte copy known as a .wud file.
Here is a quick comparison:
For enthusiasts of Nintendo Wii U emulation, managing game files presents a significant storage challenge. Original Wii U disc images, known as files, are notoriously large—often hovering around the 25 GB mark for a single game. This massive file size can quickly deplete hard drive space.
If you use the Cemu emulator to play your Wii U games, the .WUX format is arguably the best format to use. Cemu supports loading .WUX files natively, which is a massive advantage over loading raw .WUD files.
