    Hi guys , i am having some issues with Rom Hacking.

    Recently i got into the files of Mario Sports Supestars (CIA) and got the ROMFS folder.

    The game is enterily compressed and 99% of the files are compresed in various .dat files.

    My question is , does anybody know how to open these files to extract the contents?

    I was looking forward to possibly mod this game , specifically the voices and music.

    Here are some screenshots of the ROMFS

    I mainly am looking for the sounds of this game , which i am guessing are inside the na folder.

    Please if anybody knows how to start solving this i would appreciate it so much , i have done some research but i'm not having any luck solving this on my own.

    Sound files should be inside the folders. Can you post an image with the folders content?

    Thanks for replying.

    I posted the images though. the romfs_ext is the main folder.

    this is the na folder
    [​IMG]
    this is the ma folder
    [​IMG]
    this is the ca folder
    [​IMG]
    And this is the .crr folder

    i'm guessing the sounds are inside the na folder , because of the size.

    I am guessing that too. Can you post a view of what a hex editor tells about the file?

    Ok so the hex editor says this with the files inside the na folder.

    I only get that the fs2 is somehow a SARC file and the fs1 has BGM apparently , the other one is confusing.

    I wasnt succesful. The SARC as well as others are compressed inside the DAT file , and the fs2.dat doesnt seem to be opened with SARC tools.

    I will look into it. Currently I'm working massively on compression and archives. So we'll see how it's going.

    Thank you so much for your interest.

    Do you need me to send you the files so you can check them?

    Ok, fs1.dat is definitly the music. I don't know how to extract it yet, but at least we know that for sure. I will come back to that file later, but since I have no knowledge of music I would only be able to extract the files but not to create a player or something like that to hear the sounds.

    fs2.dat... Yh, SARC, huh... the header would let you suggest that. But beside that it's in no case a simple archive. Also I don't the compression method if there was one in use. That will be interesting.

    fs0.dat, absolutely no idea. If that are the voices I would say the beginning is some sort of index, following the file data (so the voices maybe).
    But as stated for fs1.dat, I'm not able to write a player or something. Only extraction and repacking then.

    What I find curious is, that this is a mario game from Nintendo but doesn't seem to rely on much standard formats.

    fs2.dat is indeed a SARC archive. It's very small and seems to be a modified version. But fs2.dat only contains of 3 CRO0 files. CRO0 are some sort of DLLs for the 3DS:
    https://www.3dbrew.org/wiki/CRO0

    fs1.dat is a NUS3 archive. I found out it's the audio format of Smash Bros. 4 for example. And also found an editor for them:
    https://github.com/DanSyor/NUS3BANK-Editor

    fs0.dat is a complete riddle to me. Sry. Until I found one that helps me understand it I can't do something about it.

    Thanks!

    I found out about fs1.dat a while ago.

    It contains the Menu music of the game and the music samples in the collection room sound test.

    The music used in the actual game + the voices are in fs0.dat , that's why the file is so big.

    Ironically that's the one file i need and the only one i can't open out of these (i don't think fs2.dat has something important to me)

    From this game? Most likely if we find out where the files are and how to read them.
