Extract text from Wii U disc images (WUD)
To convert WUD disc images to another format, you need Cemu or other Disk Image software.
To convert other file formats to the "Wii U Game Dump" file type, you need software like Cemu or a similar tool.
A .WUD file is an exact, uncompressed raw backup of a Nintendo Wii U physical optical game disc. These files act as 1:1 virtual copies of the game media and are primarily used by emulation enthusiasts to archive and play console games on PC hardware.
To run a .WUD file, you must use a dedicated emulator like Cemu. Because these files are encrypted by Nintendo, the emulator also requires a keys.txt file containing the specific title key for the game, along with the Wii U common key, to successfully decrypt and execute the game data.
The primary disadvantage of the .WUD format is its massive, inflexible size. Because it is a 1:1 sector dump, every uncompressed file is exactly 23.3 GB, regardless of whether the actual game data is 2 GB or 20 GB. The remaining space is filled with useless padding. Furthermore, the format is proprietary, heavily encrypted, and not supported by standard operating systems or web browsers.
To save storage space, users typically convert .WUD files to the highly compressed WUX format using tools like Wii U Image Chopper. Alternatively, the disc image can be unpacked into its core components (such as RPX executables and raw game assets) using specialized extraction utilities.
This format is notoriously difficult to process. It is a closed, proprietary, encrypted format that exceeds the realistic upload limits of standard web tools. Standard online converters fail to process it. Just drag and drop your file to convert.guru to see what it is and convert it if supported. While multi-gigabyte uploads are impractical, our engine can analyze file headers, inspect embedded metadata, and identify the file type to point you toward the right local decryption tools.
Convert.Guru analyzes your WUD file, detects the exact format, and lets you read the text inside.
Users also converted WUX, ZIP, WUA, ISO, 7Z, RPX, GDI, GG and APP files.
If you want to convert WUD file to APP, WUX, ISO, IMG, DMG, VHD, VMDK, VDI, HDD, QCOW, QCOW2 or RAW, you can use Cemu or similar software from the "Wii U Game Disc Backup" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to WUD, try Cemu or another comparable tool in the "Wii U Game Disc Backup" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WUD converter.
