As noted in, a game like Super Smash Bros. can be up to 25 GB. Compressing these saves enormous amounts of space. WudCompress

However, the modding and emulation community has a strong Linux presence. Because the source code is available on GitHub, users have ported the tool to Linux by making minor modifications to the source (such as replacing Windows-specific file functions like _fseeki64 with standard POSIX functions). If you are on Linux, you can either compile it from source using gcc or look for community builds (like the fork by John-Gee) that work under Wine or natively on Linux systems.

The primary benefit of WudCompress is extreme storage efficiency. Because original Wii U discs are always dumped at a fixed size regardless of actual game content, compression ratios can be dramatic: Super Smash Bros: Reduces from ~25 GB to nearly half that size. Super Mario 3D World: Can drop from down to just Average Savings: Many titles compress from 25 GB down to 3–4 GB. Pros and Cons

is a specialized, open-source command-line utility designed to compress raw Wii U Disc image files ( .wud ) into smaller, storage-efficient compressed files ( .wux ) without losing core game data. Created by Exallium, a core developer associated with the Cemu Wii U emulator team, this lightweight application serves as a foundational tool for the video game emulation community to optimize local storage configurations. Raw .wud files are uniformly sized at approximately 23.3 GB due to dummy padding bytes added to match physical Wii U optical discs. By removing this redundant padding data through zero-elimination, WudCompress can reduce the overall footprint of specific game images by up to 50% or more , providing an essential utility for multi-game digital archiving.
