[Your Name/Affiliation] Date: [Current Date] Abstract The WUX file format is a compressed derivative of the raw Wii U Disc image (WUD), designed to reduce storage footprint while retaining full data fidelity. However, certain emulation, forensic, or archival workflows require the original uncompressed WUD structure. This paper outlines a clear, tool-based methodology to reverse the compression algorithm—specifically LZMA and custom header stripping—to reliably reconstruct a valid WUD image from a WUX source. 1. Introduction Wii U optical discs store data in a proprietary format (WUD), typically 23–25 GB. The WUX format reduces this to approximately 5–9 GB using lossless compression and removal of padding sectors. While efficient, WUX is not directly mountable or accepted by all low-level disc analysis tools. Hence, decompression to WUD is often necessary. 2. Understanding the Format Differences | Feature | WUD | WUX | |---------|-----|-----| | Raw size | ~25 GB | ~5–9 GB | | Compression | None | LZMA | | Header | Standard Wii U disc header | Simplified header + compression metadata | | Use case | Emulators (Cemu), raw hex analysis | Archival, distribution |
