Wii U:Dump Games

For support (in English) with dumping Wii U discs, join Nintendo Homebrew on Discord.

It is ILLEGAL to share the files dumped with this guide. If you intend to use this guide to share your dumped games, don’t.

Install to NAND

Installing a game to the system memory (NAND) is not recommended as it’s limited to either 8GB or 32GB depending on your model, making you run out of space pretty quickly if you want to install multiple games.

What you need

• Your SD Card needs to have enough space to fit the game you want to dump.
• The latest release of WUP Installer GX2.
• The disc2app homebrew application

Instructions

1. Copy the contents of the wup_installer_gx2.zip file to the root of your SD Card.
2. Copy the contents of the disc2app.zip file to the root of your SD Card.
3. Take the SD Card out of your PC and plug it into your Wii U.
4. Power on your Wii U.
5. Eject your game disc if you have one inserted.
6. Launch the Homebrew Launcher and start the disc2app app.
7. Press the A button to start the dumping process to the SD Card.
8. When prompted, insert the game disc you want to dump.
9. When the process is complete, your Wii U will launch the Wii U Menu.
10. Launch the Homebrew Launcher and start the WUP Installer GX2 app.
11. Select your game (WUP-X-XXXX), press Install and confirm with Yes.
12. Select NAND as the installation destination.
13. When the process is complete, launch the Wii U Menu.
14. You should see your game installed, ready to be played.
15. Take the SD Card out of your Wii U and plug it into your PC.
16. Delete the WUP-X-XXXX folder in the install directory on your SD Card to free up space.

Install to USB

When installing a game to a USB device, we recommend that you use an HDD and not a flash drive, as those are not optimized for constant reading and writing, therefore making them fail quickly. If your HDD is not externally powered, you will need a Y-cable to connect it to two USB slots on the Wii U.

In order to install to a USB device, it has to be formatted by the Wii U. Doing this will erase all contents of it, and prevent it from being used on another system unless you reformat it.

What you need

• Your SD Card needs to have enough space to fit the game you want to dump.
• A USB HDD (+ a Y-cable if needed)
• The latest release of WUP Installer GX2.
• The disc2app homebrew application

Instructions

1. Copy the contents of the wup_installer_gx2.zip file to the root of your SD Card.
2. Copy the contents of the disc2app.zip file to the root of your SD Card.
3. Take the SD Card out of your PC and plug it into your Wii U.
4. Plug your USB HDD into the Wii U.
5. Power on your Wii U.
6. Your Wii U will prompt you to format your HDD. Confirm with Yes.
7. Eject your game disc if you have one inserted
8. Launch the Homebrew Launcher and start the disc2app app.
9. Press the A button to start the dumping process to the SD Card.
10. When prompted, insert the game disc you want to dump
11. When the process is complete, your Wii U will launch the Wii U Menu.
12. Launch the Homebrew Launcher and start the WUP Installer GX2 app.
13. Select your game (WUP-X-XXXX), press Install and confirm with Yes.
14. Select USB as the installation destination.
15. When the process is complete, launch the Wii U Menu.
16. You should see your game installed, ready to be played.
17. Take the SD Card out of your Wii U and plug it into your PC.
18. Delete the WUP-X-XXXX folder in the install directory on your SD Card to free up space.

Install from USB

If you do not have enough space on your SD Card, you can use an advanced technique to install dumps from a USB device. This is not the easiest thing to do and has the disadvantage of only being able to install the game onto your system memory (NAND).

What you need

• A USB storage device (+a Y-cable if needed) with enough space to fit the game you want to dump.
• The disc2app homebrew application.
• The Mocha FAT32 homebrew application.
• The Homebrew Launcher Installer payload.
• This Mocha32_Wup_Installer_Files ZIP File.

Instructions

Your USB device will need to be formatted as FAT32. If your USB is not formatted to FAT32, use GUIFormat with 32k (32768) Allocation unit size to format it.

1. Copy the contents of the Mocha32 Wup Installer Files.zip file to the root of your USB device.
2. Copy the contents of the disc2app.zip file to the root of your USB device.
3. Copy the contents of the mocha_fat32.zip file to the root of your SD Card.
4. Copy the payload.elf from the homebrew_launcher_installer_20220105-152451.zip to /wiiu/payloads/homebrew_launcher_installer on your SD card.
5. Insert your SD Card into the Wii U. Leave the USB device out for now.
6. Power on your Wii U while holding the "B" button.
7. Select homebrew_launcher_installer in the payload selection menu. Your console will now boot the Wii U Menu
8. Insert the USB Device into the Wii U. Press "No" when it asks you to format..
9. Open the Homebrew Launcher by launching Mii Maker.
10. Run the Mocha FAT32 application while holding B and set the following settings:
    • Config view mode: default
    • Skip this menu on launch: on
    • Show launch image: on
    • Don’t relaunch OS: off
    • Launch System Menu: on
    • RedNAND: off
11. You should now be taken to the Wii U Menu, but the USB device replaces the SD Card.

13. Press the A button to start the dumping process to the USB Device.
14. Eject any inserted game disc and press the A button to begin the dumping process.

Moving Games to USB

If you don’t want to keep the game installed on NAND, you can use the Wii U’s data management to move the game to a USB device.

In order to move your game to a USB device, it has to be formatted by the Wii U. Doing this will erase all contents of it, and prevent it from being used on another system unless you reformat it.

1. Plug your USB device into the Wii U.
2. Power on your Wii U.
3. Your Wii U will prompt you to format your USB device. Confirm with Yes.
4. Open the Wii U’s System Settings.
5. Navigate to Data Management > Copy/Move/Delete Data > System Memory > Move Items (X)
6. Select the game and move all data (including updates and DLC if any are installed) to your USB device.

Moving Updates to USB

If your disc game had DLC or updates installed, you will need to transfer the files over to your USB device. You can do this using the Wii U’s data management.

1. Power on your Wii U
2. Open the Wii U’s System Settings.
3. Navigate to Data Management > Copy/Move/Delete Data > System Memory > Move Items (X).
4. Select your game and move the update and DLC data to the USB device.
