Nintendo Wii U Dumping Guide

From wiki.redump.info Wiki

This guide is a work in progress.

Retail Discs

Tools

  • Wii U console with a network connection
    • Networking only required for soft-modding
  • 32GB+ SD Card formatted to FAT32.
    • (Optional) Additional 32GB+ USB storage device formatted to FAT32 or NTFS.
    • Higher sizes are recommended as all WUDs are 25GB. Please note that some external hard drives require a Y-Cable or external power, as the Wii U's USB ports don't supply much power.
  • WUDD (Wii U Disc Dumper) or WUDump, to dump the actual game.
    • If you use WUDD, you will need a tool that can calculate hashes such as Hashcalc or OpenHashTab.
    • WUDump does not work on systems with modern CFW environments (eg; Aroma).


First Time Setup

  • Soft-mod your Wii U using the Wii U soft-modding guide for Aroma. If you have an older custom firmware installed, the guide has instructions on how to upgrade as well. You may also use an older custome firmware with WUDD (Tiramisu only) or WUDump (other environments).

Option 1 - Setting up WUDD

  • Download WUDD from above. If you followed the guide to install Aroma, use the .wuhb release. If you are using Tiramisu, download the .rpx release.
  • Copy the wiiu folder to the root of your SD Card.

Option 2 - Setting up WUDump

  • Download WUDump from above, and place it in SD:/wiiu/apps/wudump/ (you will need to make the folder 'wudump')


Dumping

Option 1 - Dumping with WUDD

  • Load WUDD through the Homebrew Launcher (Tiramisu) or the Wii U Menu (Aroma)
  • Insert the disc and select which device you would like to dump to (FAT32 SD or NTFS USB) and then select Dump as WUD.

If you dumped to a FAT32 device, the WUD will be split into 12 .part files that you need to combine. To do this:

  • Copy the folder containing the part files to a file system with large file support (eg NTFS)
  • Open a command prompt there and then copy and run the following command
copy /b game.wud.part1 + game.wud.part2 + game.wud.part3 + game.wud.part4 + game.wud.part5 + game.wud.part6 + game.wud.part7 + game.wud.part8 + game.wud.part9 + game.wud.part10 + game.wud.part11 + game.wud.part12 game.wud

You should now have two files, game.key and the full game.wud (the .part files are not needed anymore and can be deleted)

  • Run Hashcalc, press the '...' button and select the game.wud file.
  • Tick the MD5, SHA-1 and CRC32 boxes then click 'calculate'
  • Open notepad, copy the template below and replace the data in <Angled Brackets> with the version of WUDD used and the data from Hashcalc.
  • (If a new disc) Using a hex editor, open game.wud and copy the Internal Serial into "Comments".
Dumped with WUDD - Wii U Disc Dumper <Version of WUDD used>
MD5: <Paste the MD5 from Hashcalc here>
SHA1: <Paste the SHA1 from Hashcalc here>
CRC32: <Paste the CRC32 from Hashcalc here>
Internal Serial: <Paste the Internal Serial from your disc image here>
  • Save the file as game.txt
  • Keep your game.key decryption key file for personal use.


Option 2 - Dumping with WUDump

  • Run the Homebrew Launcher.
  • Once in the Homebrew launcher, select wudump, then hit Load.
  • Press the appropriate button for what device you are dumping to (FAT32 USB, NTFS USB, or FAT32 SD)
  • Once ready, the program will inform you to insert the disc; if you already have the disc inserted, simply eject and re-insert.
  • This process takes a long time (1-2 hours!), so go get lunch and wait.

If you dumped to a FAT32 device, the WUD will be split into 12 .part files that you need to combine. To do this:

  • Copy the folder containing the part files to a file system with large file support (eg NTFS)
  • Open a command prompt there and then copy and run 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

WUDump should create a log file with the remaining info that you need for submission.


Development Discs (CAT-R)

CAT-Rs can be dumped two ways:

  • Disc Dumping Guide (MPF) with a Blu-Ray drive. MediaTek-based and Pioneer-based PC bluray drives have been confirmed as able to dump CAT-R discs. It's highly likely other drive models work as well (but have not been confirmed).
  • Using the regular homebrew dumping methods, but on CAT-I/CAT-R/CAT-DEV hardware.


Submitting Info to Redump

Please review the important guidelines outlined in the Getting Started Guide. Submit all dumps through the New Disc form.

Notes on using the New Disc form:

  • Language Select - you can mark as either "Language select via BIOS system settings" or "Language select screen at startup". Should go in the 'Comments' field.
  • Case serial number information can go into the 'Comments' field.
  • Ringcode reference:
