    Hello Community,
    right now I want to create a regionfree cia of Bravely Second.
    The Problem: None of the existing converters are able to create a regionfree cia with using the original .3ds and xorpads.
    Now I've created the xorpads and used MEX to merge exefs_norm.xorpad and exefs_7x.xorpad.

    I'm really new in doing things like this and now I want to know how I can decrypt the Encrypted Files (romfs, exefs and exh) by using the xorpads.
    I want to change the Region in the icon.bin (02 00 00 00 to 7f ff ff ff), and build a cia out of the decrypted/modified files.
    How can I do this?
    COuld someone write me a simple tutorial, please?
    I guess when I decrypt all the files manually, I would be able to create a regionfree cia.


    EDIT:
    How can I extract the files from a romfs-file?
    I want to rebuild it

    I tried today to generate the xorpads by myself and it worked just fine. It was a bad xorpads issue?
