DumpsterU - Wii U Harddrive Dumper
DumpsterU makes it really easy to dump your installed contents with very high speeds.
You can dump your saves, games, updates and DLCs straight from your Wii U-formatted harddrive to your PC.
It will dump decrypted contents that you can use with Cemu or other applications.
You need a OTP and SEEPROM backup from the console the harddrive was formatted with. You can get the backup with Wii U NAND Dumper.
Select your hardrive from the list and open your otp.bin and seeprom.bin.
A list with all the games installed to that harddrive will open.
Tip: You can press Ctrl + F to search or click on one of the headers to sort the list.
Click on the title you want to dump, select an output folder and press on one of the buttons to dump the contents.
You can download DumpsterU from the releases page.
Currently Windows and Ubuntu builds are available.
Where are my Wii VC saves?
They are stored on the NAND and cannot be dumped by this tool.
Why do I need my OTP and SEEPROM?
The contents of the harddrive are encrypted and the OTP and SEEPROM contain keys used for decrypting.
How fast is this?
The 14GB from Breath of the Wild were dumped in 1:40 minutes. This depends on harddrive speed though.
Run the installer
Run from commandline:
koolkdev who made all of this possible by reverse engineering the Wii U's filesystem and creating wfslib
