    Before doing this, make sure you have the correct common key. It should start with D7B. (I obviously can't provide the entire key. That would be... problematic. ;))

    There is a trick to using those keys. Wud2app does not work directly with keys in text form. They need to be in raw data. You can do that pretty easily with a hex editor. Use an online hex editor like In the online hex editor, choose "new file". Now, copy your key in text form. Don't paste yet. In the online hex editor, click on the blank area that has a small "+" symbol on it right next to the 00000000. Press control + v to paste. A window will pop up. The window will have a drop down box that says "binary data/text". Change it to "hexadecimal values". Now press apply. Your key is now in the proper format, so press "export" to save your key file.

    Do the same for both your common key and your game key, and you will be good to go! :yayu:

    Just so you know, you might want to remove Wii U USB helper from that list since it's been discontinued.

    Also is one of the two tools for compressing wuds better than the other? Just curious if there's any difference between the two. Same with disc extractors, any difference between them?

    I don't think I need to remove it. at best, just note that it's discontinued, but keep it for historical reference.

    as for tools differences, they often don't have any differences except the GUI, or design.
    One might be a windows command line tool, while the other is a Java (multi-plateform) or Python (multi-plateform) tools.
    Some might need more data than others (like common key in text, or binary external file, or not needed at all)
    Read each program's requirements and Pick the one you prefer.
