Wudcompress

The primary difference between the WUD and WUX formats lies in their structure:

: The process is lossless, meaning the original game data is preserved exactly as it was on the disc. Context & Usage

Since there is no formal research paper, you can find the technical implementation and usage guides at these sources:

A significant aspect of WudCompress is its nature. Old-school modding tools (like WiiScrubber for the original Wii) would sometimes strip out "unnecessary" update partitions or filler to save space, which permanently modified the data and occasionally led to crashes on specific hardware.

Drag the .wud file and drop it directly onto the wudcompress.exe icon.

Not everything was simple. The mayor, a man who valued monuments, brought a statue that had grown into a small hill. “Make it noble but smaller,” he requested, and Min obliged. WudCompress answered with a version of the statue that retained the mayor’s sculpted pride but encouraged hands to touch rather than gaze from distance. The mayor’s pride softened. For a week he kept his hand on the slim plinth when he thought no one watched. The primary difference between the WUD and WUX

The source code and basic README are hosted on the cemu-project GitHub.

There is also a Java alternative to the tool called , which offers some additional features, such as decrypting the game partition directly from the WUD or WUX. However, for standard compression and decompression, WudCompress is the preferred tool due to its speed and small binary size.

Original Wii U disc dumps, known as WUD (Wii U Disk) files, are raw images that represent the entire capacity of the physical disc. Because Wii U discs are 25 GB layers, every WUD file is roughly , regardless of how much actual game data is on the disc. For example, a small game that only uses 2 GB of space would still result in a 23.3 GB file filled mostly with "padding" or empty data. Drag the

Once complete, a new .wux file will be created in the same directory.

Essential for users with large digital collections of physical disc backups.
