    Hi,
    I want to edit a couple emuNAND system savedata; I managed to xor the image and extract it, but I can't open any of the archives in which the .dat files are stored.
    For example, \\data\[ID]\sysdata\0002009f\ should contain the Friend List savedata.
    The folder contains a file with the name '00000000' and no extension. I tried opening it with an hex editor and I can see some .dat files references (fSave.dat, in this case) and a lot of messed up strings. What type of archive is that? Is it encrypted?

    There is a FUSE tool for dealing with this if you are on Linux.

    I'm on Windows, are there any alternatives?
    EDIT: I could still set up a Linux distro on VM though

    I don't think there are any Windows versions. The FUSE tool is on yellows8's github,

    Is that darctool? 3DSExplorer can open .(D)ARC files, so I could try with that (or try to compile yellows tool on windows)

    Not darctool. It's the ctr-nandmount one.

    Oh, I understand now.
    Windows doesn't include support for userspace filesystems by default, so I'd need an equivalent of FUSE. I'll install a VM with OpenSUSE, it's much more convenient
