Dumping Updates and DLC (FTP)

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 updates and DLC 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 updates/DLC. This is done using an exploit in the Wii U browser.

TIP

These instructions are nearly identical to copying over digital games, however we will copy the update/DLC files to another place and install them a different way.

Introduction

For this method, we will be copying update/DLC files over the internet using an FTP (File Transfer Protocol) server and client. This allows you to copy files over your local network directly to your computer.

DANGER

This process involves accessing the Wii U internal memory! If you don't follow the instructions correctly, you could potentially cause serious damage to your console.

Requirements

• An SD card for homebrew and dumping

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
• A modified release of FTPiiU (FTP Server)
  • If you use (Coldboot) Haxchi, download the latest release of FTPiiU (FTP server)
• The latest release of FileZilla (FTP Client)

Preparations

1. Download and install FileZilla to your computer
2. Extract the mocha.zip file to the root of your SD card
   • If prompted to, replace any pre-existing files
3. Extract the homebrew_launcher.v.1.4.zip file to the root of your SD card
4. Copy the config.ini file to the /wiiu/apps/mocha folder on your SD card
5. Copy the payload.elf file from the payload.zip file to the /wiiu folder on your SD card
6. Download and move the ftpiiu.elf file to the \wiiu\apps folder on your SD Card
7. Ensure you have enough space on your PC for your game
8. Eject your SD card from Windows and put it into your Wii U console

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

Dumping Files

Connecting via FTP

1. Run FTPiiU Everywhere from the Homebrew Launcher
2. On your screen you should see a line saying:
   Listening for data connections at xxx.xxx.xxx.xxx:PORT
   where each x and PORT is a number
   • This is the IP address and port of your FTP server
3. Keep this screen open on your Wii U
4. On your computer, open FileZilla
5. Enter in your IP address to the Host field on the top bar
   • This is the xxx.xxx.xxx.xxx part
6. Enter in your port to the Port field on the top bar
   • This is the PORT part
7. When warned about an insecure connection, ignore and continue
8. You should now see your Wii U storage displayed on the right half of the FileZilla window

Transferring Files

1. If your game is stored on your Wii U internal memory, navigate to storage_mlc/usr/title/
2. If your game is stored on a USB storage device, navigate to storage_usb/usr/title/
3. If you want to dump an update, open the 0005000E folder
4. If you want to dump DLC, open the 0005000C folder
5. In this directory, you should see folders with 8 character names
   • This is the last 8 digits of each game's "Title ID", which allows to Wii U to uniquely identify each game by a number, instead of a name
6. You can use the full list of each game's Title ID to identify which game is which, found here
   • Copy the Title ID of the game and use Ctrl+F to search for it
7. Once you've found the game you want, drag and drop it to a folder on your PC on the left-side panel of FileZilla

TIP

A lot of the data-less files will fail to transfer, but these can be ignored. To be safe, make sure to retry all failed downloads before exiting to ensure that all files that should be transferred have done so.

Your game should now begin copying over to your computer. This will take a very long time and you may want to go do something else while this is happening.

After this is finished, you can exit FileZilla and turn off your Wii U.

Installing to Cemu

1. Open the Cemu application
2. On the top bar, navigate to File -> Install game update or DLC
3. Navigate to and open the folder of your update/DLC dump
4. Open the meta folder
5. Select the meta.xml file

Cemu will now automatically install your update/DLC to your mlc01 storage folder. This may take some time.
