I have my full WiiU Nand backed up. Can I use it on CEMU?

    Guys,

    That is the question. Anybody knows how, or if I can use the full NAND of my WiiU and use it on CEMU? I already sold my WiiU, but I made sure to backup my full 8gb NAND files and some of the other files needed.

    The thing is, I haven't found anything regarding a FULL Nand dump and Cemu. I have seen tutorials were people use Filezilla to extract some files from their WiiU's to play online on CEMU.

    How could I do this, if I have my full NAND? (but not my WiiU)

    If anyone knows anything, please let me know! It would be good to extract my saves also!


    Cheers guys and thanks in advance :lol:

    You need the NAND key for that, and I believe it's console unique. And since you no longer have the console there's no way for you to get the key.

    Idk, a Black Hole maybe?
    Your nand is encrypted (or at least that's how it works with Nintendo's other consoles) The only way to decrypt it is a console-specific key. If you don't have that key, you won't decrypt the nand. You need the physical console to extract the key. There's no way to generate one, and without it all you have is encrypted garbage.

    (I have no experience with the Wii U and have never owned one, please correct me if what I say is incorrect)

    I have the NAND:

    mlc.bin.part01 2gb
    mlc.bin.part02 2gb
    mlc.bin.part03 2gb
    mlc.bin.part04 1.6gb

    These are around 8gb in total, anybody know how to extract them by the way?

    And I also have these from the same WiiU of course:

    otp.bin
    seeprom.bin
    slc.bin
    slccmpt.bin

    Isn't the "key" in any of those files? Wasn't otp.bin the file needed to decrypt the NAND?

    I wasn't that stupid too just dump the Nand without following the required steps. Or maybe I still need something else?

    Thank you guys and thanks for the help.

    otp.bin and maybe seeprom.bin are needed to decrypt the NAND. There is a tool to dump contents of WFS: https://github.com/koolkdev/wfslib (read the readme)

    Thank you man! You really helped me here! With this I will be able to continue!

    By te way, let's say I can use my WiiU Nand on Cemu, wouldn't I get banned if I use it with CEMU? That is, if the the new user also uses the WiiU? Though I told the guy specifically NOT TO ever use my user (where Haxchii is installed).

    I haven't heard a clear answer on that issue really.

    Thanks again! You guys are great!

    Wii U bans are pretty rare, the only times I've heard of it happen was as a result of using detectable cheats in games like Splatoon.
    But since you are basically cloning the Wii U anything could happen.

    The funny thing is, a had already Unbanned that console, because a douche sold it to me completely banned. I remember I replaced a number in a .XML file and ta daaam, unbanned from eshop and everything else! :yayu: I have never cheated in my life.

    Maybe if I create a new user on this NAND, then I could be saved from being banned. Cheers and thanks again ;)

    Wow this is super fascinating knowing that with a decrypted NAND backup you can basically clone your console :O pat on the back to the developers.
