    Dynamit created a GUI to make it easier to decrypt Wii U game updates.

    [​IMG]

    All you need to do is to put the files you downloaded from NUS in the same folder as WU CDecrypt GUI and point the program to the title.tik and title.tmd. Also you need to point the program to the WiiU Common key.Next you have to download cdecrypt.exe and libeay32.dll from here and place them in a subfolder called “include”.

    After that it should decrypt and create a debug.txt file.

    A requeriment to get the app to work is .Net Framework 2.0 or later.

    Credit goes to the following people:

    Dynamit for creating WU_Decrypt Content GUI.
    Luigi for the idéa to create a GUI front.
    Fix94 & Dimok and many other big names in Wii/WiiU homebrew
    world for there wounderful work.
    crediar for CDecrypt that does the all heavy lifting.

    UPDDATE:

    0.5.1 Is Out

    I know but NUS Downloader U (I thought because of an update folder or something like that. I know the WUD does) will not Extract Hyrule Warriors properly with cdecrypt so I assume that this won't either :/

    Does this also decrypt VC games from NUS?

    If this is intended only for WiiU updates why do you still have to point it to those files? I mean, they should always be included.

    It's not like it needs to be changed but if he "forces" you to already place the executable into the same directory as the files.

    You say "source" but there's no source-code available for that application. Just a little bit confusing.Here are the changes I mean, you can just forward that to him: (We're using system.io here)

    Currently he checks if his string array is empty or not (btw. he might want to set a dimension for it but not really needed I guess)

    Put this:

    Code:
                if (File.Exists("cetk")
                        filePaths[1] = "cetk";
                if (File.Exists("tmd")
                        filePaths[1] = "tmd";
    before this:

    Code:
                bool flag = string.IsNullOrEmpty(this.filePaths[0]) || string.IsNullOrEmpty(this.filePaths[1]) || string.IsNullOrEmpty(this.filePaths[2]);
                if (flag)
                {
                    ...
                }
    You might want to do the same for the WiiU common key. It won't change the function at all but just skip most steps. In addition, you can tell him that he doesn't need to create for everything a new variable. Obviously it's up to the programmer but this also works:

    Code:
                    if (string.IsNullOrEmpty(this.filePaths[1])
                    {}
    On the bright side I won't need to make you that program anymore :)

    It should decrypt a full title of NUS as long as you have the extracted files title.tik, title.tmd from a full .wud.

    Thanks a nice app here! great work.

    Can someone guide me to do this?
    I've been trying to get VC games from NUS but I cannot seem to be able to get the title.tik, tmd files from the downloaded package.
    Is there away to decrypt those so far?

    The title.tik isn't public. It's basically the decryption key for the package and you would need to obtain it from somewhere else and save it into a file.

    Edit: The key is different from the normal decryption key. It's more or less a "nus specific" key. So the normal decryption key for a game can be different from the key for the nus download. For patches the key is provided from nus itself.

    I haven't seen one yet. :/

    I've been trying to get both Mother and mother 2 ROMs (Japanese VC) from there to make an in-depth comparison with the already available ROMs with no luck at all.
    I thought about using NUS + Decryption to dump the ROMs but no luck at all. :/

    You can't use the keys of a patch. Basically every game / patch has a different key, the common key stays the same (you need multiple keys here). Currently there's no place where you can get nus keys and/or the title.tik files for VC games (at least not that I know of, I think I saw somewhere a google sheet with nus keys for most AAA games)

    yea there is one
    ive used it before
    ive got freedom planet VC
    but because there are no keys
    i cant do shit with it

    do you think it will be possible to use cheat engine to force a decrypt
    is it limited by the software
    or is it limited by Nintendo servers?

    This is litteraly what I said, you can download every VC title from NUS but you most likely won't get the keys for them. You might, some day from some place, but don't get your hopes up. NUS isn't a place to get free games.
