    Hi,
    I'm in need of a way to extract data, or open an .app file. Usually from system apps. I've been looking for stuff that I believe is buried in them but I have no way of opening. Right now, all I have is this.

    Any help would be appreciated.

    what file is that you are even trying to open? Those files are encrypted with console unique keys.

    I'm trying to extract the HOME Menu audio of the eShop, because no high quality version exists anywhere.

    So, the banner (instead of the BGM you were asking for a few days ago)?

    The banner is (3) found in the exefs, which is part (2) of the cxi (= the main (content id 0) NCCH, which an .app file could be - probably the largest one of the two and the other is a manual with content id 1), which could be packaged inside a cia (1) or found loose (and encrypted if on SD) if already installed

    Traditionally you extracted
    1 with ctrtool the.cia --contents=whatever
    2 with 3dstool -xvtf cxi whatever.0000.* --exefs=exefs.bin
    3 with 3dstool -xvtf exefs exefs.bin --exefs-dir=exefs
    GM9 and probably fuse-3ds can do all of that too

    Once you get the banner file you can split it with PC programs such as ba-gui-nnertool, then you still are left with a propretary BCWAV which you probably want to convert to a common sound format
