    1- Is it possible?
    2- If it's possible, how can I get, for example, the music from a CIA rom?

    Please guide me.

    If the cia is installed, you can decrypt the files like you would normaly do using SDinfo_gen.py fetching their xorpads.

    example:
    1. padxorer 00000020.app title.0004008c.00009800.content.00000000.00000020.app.xorpad >> 00000020.app.out
    2. ctrtool --romfsdir=romfs 00000020.app.out

    Usualy Music is .bcstm >> https://gbatemp.net/threads/release-every-file-explorer.373615/

    Save it as .wav ^_^

    Depends, if the cia was generated from .3ds, you can try "makerom -ciatocci <name_of_cia>.cia"

    If its from funkycia, makerom will fail to do this, you need to create xorpads to get romfs after installing it!

    If it's a converted CIA then usually those are decrypted.

    If not then extract the ncch then use the decryptor.

    As Duo8 said, the cia you are using is already decrypted - if its encrypted, makerom would have failed!

    1. ctrtool -p --romfs=decrypted_romfs.bin <your_cci>
    2. ctrtool --romfsdir=romfs decrypted_romfs.bin

    Thanks all!
    Problem solved.
    BTW this method doesn't seem to work with 4GB CIA's (like Bravely Default). How can I extract the music from 4GB CIAs

    using the SD utility on O3DS locks up rxtools, even with NTR loaded. It works as it does on N3DS if I use Gateway. I heard that you could rebuild the .cia somehow to make it work under rxtools. Does anybobdy know the steps to do this?
