To run your own games on your computer, install your disc games onto your console, or create mods, a dump of your games will be needed. There are a variety of file types that Wii U games can be dumped as, each with their own uses, and each with their own method of being dumped.

Method 1: wudump

This method will dump the entire Wii U disc as a WUD file. This file contains all of the contents of the game disc, including blank space, and will need 23.3 GB of storage free in the device you are dumping to. WUD files are the most complete versions of a dump, although they are the largest in size.

Requirements:

  • A homebrewed Wii U with the Homebrew Launcher installed
  • The latest version of wudump.
  • A FAT32 SD card/USB drive or NTFS USB drive with at least 23.3 GB of storage free
    • Using a FAT32 SD card will add an extra step to combine files

Steps:

  1. Download wudump.elf and place it in your SD card's /wiiu/apps/wudump folder
  2. Take out any disc currently in your Wii U console
  3. On your console, open the Homebrew Launcher and launch wudump
  4. Once loaded, press the A or B button to choose your destination device. A for SD, B for USB
  5. Wait for the prompt to insert the disc you want to dump, then do so. This step will take about an hour to complete.

If you used an NTFS device, you should now have a completed WUD file. If you used a FAT32 device, it'll be split into multiple files that you'll need to combine. To do so, open a command prompt in the folder containing the part files called "game_partX.wud". Then, copy the following command:

copy /b game_part1.wud + game_part2.wud + game_part3.wud + game_part4.wud + game_part5.wud + game_part6.wud + game_part7.wud + game_part8.wud + game_part9.wud + game_part10.wud + game_part11.wud + game_part12.wud game.wud

which will create the full game.wud file in the same directory. You can then rename and move this file, as well as delete the part files in the folder.
From here, you can either compress to a WUX file using JWUDTool, extract it for installing onto your console using wud2app, or used with an emulator such as CEMU.

Method 2: disc2app

This method was made combining wud2app and wudump into one app, directly giving you the encrypted content files in the form of .app, .h3, .tik, .tmd, and .cert files. These will be significantly smaller, only containing the actual game files and no empty space. They can be installed onto your console or used with an NUS content decrypter to view and modify the game's files.

Requirements:

  • A homebrewed Wii U with the Homebrew Launcher installed
  • The latest version of disc2app.
  • A FAT32 SD card/USB drive or NTFS USB drive with at least 23.3 GB of storage free
    • The file size will be smaller that 23.3 GB for almost all games, but some games like Xenoblade Chronicles X take almost the entire disc space

Steps:

  1. Download disc2app.zip and extract the wiiu folder to the root of your SD card
  2. Take out any disc currently in your Wii U console
  3. On your console, open the Homebrew Launcher and launch disc2app
  4. Once loaded, press the A or B button to choose your destination device. A for SD, B for USB
  5. Wait for the prompt to insert the disc you want to dump, then do so. The time for this step will vary depending on the size of the game.

After this finishes, you should have a folder named the game's product code (WUP-X-XXXX). This can then be directly installed onto your console using a WUP installer, or decrypted using a content decrypter to view the game files.
