Dumping Games

If you need further help, ask on the official Cemu Discord Server for assistance.


In this section, we look at how to “dump” (copy) your games, updates, DLC and saves from your Wii U system over to your PC.

To do this, we’re going to need to use a custom homebrew application to dump your games. This is done using an exploit in the Wii U browser.

Requirements

  • An SD card for homebrew
  • (Optional) A USB storage device to dump the game to
    • Only required if the game is too big for the SD card
    • Wii U games can vary in size up to 17GB, but having 12GB of storage should be okay for most games

Downloads

  • The latest release of MochaCFW
    • This will also work with (Coldboot) Haxchi
  • The Mocha config
  • The latest release of Homebrew Launcher Installer
    • You will need to download the payload.zip file
  • The v1.4 release of The Homebrew Launcher
    • You will need to download the v1.4 homebrew_launcher.v1.4.zip release of The Homebrew Launcher
  • The latest release of dumpling

Preparations

  1. Extract the mocha.zip file to the root of your SD card
    • If prompted to, replace any pre-existing files
  2. Extract the homebrew_launcher.v.1.4.zip file to the root of your SD card
  3. Copy the config.ini file to the /wiiu/apps/mocha folder on your SD card
  4. Copy the payload.elf file from the payload.zip file to the /wiiu folder on your SD card
  5. Extract the dumpling.zip file to the root of your SD card
  6. Eject your SD card from Windows and put it into your Wii U console
  7. Plug a USB storage device into your Wii U if you want to dump to USB storage
    • Some users have reported better performance using the back ports, however the front ports should be fine too

Launching MochaCFW

  1. Turn on your Wii U console
  2. Launch the internet browser and open wiiuexploit.xyz
  3. Tap Run Homebrew Launcher!
    • If your console freezes for more than 10 seconds, hold down the Power button for 4 seconds and reboot
    • Once rebooted, reset the browser’s save data and try again
  4. Once in the Homebrew Launcher, launch MochaCFW
    • This should return you back to the Homebrew Launcher, where we will now launch dumpling

Using dumpling

If you notice slowdowns while using dumpling, try copying via FTP or disc2app instead. This is useful on large games such as Breath of the Wild.

  1. Run the dumpling app from the Homebrew Launcher
  2. Use (ZL) and (ZR) to toggle between dumping to your SD card or a FAT32 USB device
  3. Select Account Data using the (A) button
    • If you’d like to dump a disc, also select “Disc dump”
  4. Press (START) to begin dumping
    • If you’re dumping a disc, skip to step 13
  5. Once finished, press (X) and wait for the metadata to be fetched
    • This can take up to 5 seconds for every title installed, be patient
  6. Use (L) and (R) to toggle between dumping from internal storage or from USB
  7. Press (A) to select the titles you’d like to dump
  8. Press (START) to continue
  9. Press (A) to select which parts of the title you’d like to dump
    • This will apply to all titles you selected previously
  10. Press (SELECT) to begin dumping
    • This can take a very long time
  11. Once finished, turn off your Wii U and put your SD/USB that you dumped to into your computer
