Dumpling is an all-in-one Wii U file dumper designed to simplify the process of dumping games and files for popular emulators like Cemu.

Features

• Dumps titles, updates, and DLC from both physical and digital formats.
• All dumps are decrypted for easy use with Cemu.
• Creates 1:1 copies of data with proper meta data.
• Allows dumping to a FAT32 formatted SD or USB storage device.
• Allows you to dump system applications too.
• Dump all the files needed for Cemu online play.
• Can be run without an SD card.

Installation

Preparation:

• A Wii U with the Homebrew Launcher installed,
• A FAT32 formatted USB storage device or SD card (32GB or higher).

Method 1 via Internet Browser:

• Open the Internet Browser on the Wii U.
• Go to dumplingapp.com to launch Dumpling.
• In the event of a console freeze lasting beyond 10 seconds, perform a reboot (hold the Power button for 4 seconds). Once rebooted, delete the browser's history (from Internet Browser's Setting > Reset Save Data) and try again,

Method 2 via Homebrew Launcher:

• Download the latest release.
• Extract the dumpling.zip file to the root of your SD card.

Please refer to the Dumpling guide available at cemu.cfw.guide. It provides instructions on how to dump games, updates, saves, and account data for use with Cemu.

Changelog

v2.7.2 2024/05/12

• Updated disclaimer to Aroma users about SD card access. This'll now require rebooting your Wii U manually without Aroma (by holding R while booting) and using https://dumpingapp.com.

v2.7.1 2024/03/28

• Aroma users will now be asked if they want to enable SD card access. This does now require shutting down Aroma temporarily while Dumpling is running.
  • This is to prevent potential SD card corruption caused by Dumpling and Aroma simultaneously accessing the SD card.
  • USB sticks are always accessible regardless of the option you pick.
• Fix font rendering at the boot-up screen

v2.7.0 2024/03/27

• Add an option to dump but also automatically upload your SpotPass data to the SpotPass Archival Project.
  • This feature was specifically added because the SpotBass servers will be shutdown soon. Please consider contributing your data!
  • Thanks to @EpicUsername12 for contributing this feature!

v2.6.4 2023/04/07

• Hotfix for .rpx files on discs resulting in an error.

v2.6.3 2023/04/06

• Use product code when (some) japanese titles can't be used as folder name.
• Fix softlock when starting dumps with no games/updates/DLC present.
• Update to new devkitPPC version.

v2.6.2 2023/01/20

• Fix bug where you couldn't dump online files for non-ascii usernames. They'll now be stored using alternative folder names.
• Decreased Dumpling's binary size by using libschrift instead of freetype2 for font rendering.
• Optimized font rendering so that it's now 2x faster. This doesn't really improve dumping speed, although it might feel more responsive overall.
• Thanks to @Maschell for telling me about libschrift!

v2.6.1 2022/11/06

• Fix bug where if you had 12 Wii U accounts (which is the maximum amount allowed) the last one wouldn't show up. Thanks @jbmagination for finding and fixing this!

v2.6.0 2022/10/24

• Add official Aroma support and .wuhb releases.
  • Added a new home menu icon and boot screen, made by @emiyl.
  • Exiting while using Aroma should no longer result in a black screen.
• Major rework of file transferring code, resulting in a massive speed improvement.
  • Games with tons of files now dump up to 12x faster (e.g. Breath of the Wild which takes 25 minutes instead of 4+ hours)!
  • All games benefit from a good 2-3x improvement!
  • This was possible using a multithreaded writing process (thanks @Xpl0itU and @wchill!) and adding Dumpling-specific fat32 caching methods (thanks @Exzap for helping).
• Now uses fatfs instead of libfat.
  • Adds support for exfat drives.
  • Much improved USB drive support so that previously unrecognized USB drives now work.
  • Allows for the now multithreaded file dumping.
• Fixed jumpy dumping speed and estimated dumping time while dumping.
• Show total time after successful dump.
• Cleaned up multiple menus into a singular, more explanatory option menu.
• Can now optionally delete incomplete files if an error occurred or if you cancel while dumping.
• Fix inverted option to only dump the disc files but not the update/DLC.
• Thanks to Tomk007 and Jaimie for helping me test all of the experimental optimizations!

v2.5.0 2022/08/01

• Uses new libmocha instead of libiosuhax, improving speed and stability.
  • Thanks Maschell and GaryOderNichts!
• Give more and improved error messages
  • Finally fixes discs producing incomplete dumps without showing any errors!
• Improve dumping speeds by 1.5x and more to come!
• Allow only dumping disc files without updates/DLC to speed up dumping times by:
  • Dump updates/DLC all at once later to have to wait shorter between swapping discs.
  • Using DumpsterU, Cemu's online features or an existing MLC dump instead.

v2.4.3 2022/06/08

• Fix save files not being picked up.

v2.4.2 2022/06/01

• Fix .rpx files only being partially dumped for disc games! More permanent fix in the next proper release.

v2.4.1 2022/05/18

• Fix multiple disc dumping.
• Add some filesystem fixes found by Maschell.
• ... and some more fixes!

v2.4.0b 2022/03/15

• Enable dumping (digital) wii games!
  • Note that Tiramisu users will be asked to enable it since it involves stopping Tiramisu temporarily.
  • Since vWii games are stored in .nfs files, you'll need to use nfs2iso2nfs to convert them into .iso files for Dolphin, at least for the time being.
• Much improved errors for file copying. Maybe discs are easier to dump, so let me know!
• Added option to choose whether to ignore file copying errors in the hopes that those files aren't important/overwritten by an update.
• A lot of other changes under the hood with regards to how files are accessed so let me know if anything's wrong!
  • Disc dumping regressions were found in version 2.4.0a causing it to be revoked, these are fixed in this hotfix release.
