    What is WIT?

    wit (Wiimm ISO Tool) is part of the package WWT.

    Features:
    • wit (and the whole WWT package) is available for Linux, Windows and Mac. Current sources are always in a SVN repository.
    • It can handle ISO images in the 4 file formats PLAIN ISO, WDF, CISO and WBFS. Splitted files are used transparently.
    • It can convert from each of the 4 formats into all other formats.
    • Scrubbig and splitting on the fly.
    • Renaming ID and title in the ISO header.
    • Comparing ISO in raw and scrubbed mode.
    • Renaming ISO files using WiiTDB titles.
    • Dump the data structure inside ISO images.
    What are my plans?

    My plans are in this order:[*] wit should extract all or only selected files from ISO images to a destination directory. It should support output formats that other tools (like SNEEK) need.[*] wit should built ISO images from a file structure.[*] wit should merge an ISO image with extracted (and modified files) to a new ISO image.[*] wit should compare ISO images on file level and, if wanted, generate a (binary) patch file.[*] wit should patch ISO images with the previous generated patch file.Already realized
    • wit can list all files of WII ISO files.
    • wit can extract the files all or only selected files from ISO images to a destination directory. It support the sneek file layout.
    • wit accept rules to filter files for all commands above.
    • wit can compose an trucha signed ISO image from a file structure.
    • wit can compare ISO images on file level.
    • wit can decrypt and encrypt ISO images on the fly while copying.
    • wit can verify ISO images (find bad dumps). It do it by calculating all check sums and comparing them with the stored hash values (H0..H4).
    Brain storming and feature request!


    And now I asked you for ideas? Inspire me!

    I need also references about file system layouts (e.g. for sneek). I know that there are some archives (collection of much small files). I need technical info about this too.

    does the ID changing affect the ticket? currently the only way to change the ID in the ticket, and thus the folder the game will use for a gamesave, is with wiiscrubber & the partition.bin editor. if youre just looking for features to add, it would be nice to be able to change the save spot for a game with 1 little command rather than to have to extract the partition.bin, change the stuff, and put it back in the ISO.

    for the sneek layout, here's the basic layout...
    each partition of a ISO is put in its own folder. in that folder is the ticket, TMD, cert, and 2 more folders.
    one of those 2 more folders is called sys and it has the main.dol, apploader, fst, boot.bin, and bi2. the other folder is called files and it contains everything described in the fst. look at the spoiler in post 136 http://gbatemp.net/index.php?showtopic=217092&st=135

    Been able to just update the fst etc for sneek+di extracted files without building an ISO would be cool.

    extracting into right file structure is easy, my app already does that, 1 look @ the page on sneek wiki

    Yes, it is easy, many apps do it, you are not the first/only one [​IMG] And Wiimm knows how to extract files, the question was just which folders are needed to get it compatible with sneek.

    Is it so difficult to send me a executable of your tool?
    Comparing the identical results of 2 or more tools is the easiest verification for that tools.

    boot.bin is a constant 0x440 bytes at the start of the partition.

    bi2.bin is 0x2000 bytes right after the boot.bin

    the apploader.img follows directly behind that. read the apploader header to get the size. ( http://code.google.com/p/usbloader-gui/sou...der/apploader.c line 366 )

    you get the fst.bin size and offset and the main.dol offset from reading the last 0x20 bytes of boot.bin. shift the offsets max)
    ÂÂÂÂÂÂÂÂÂÂÂÂmax = offset + size;
    ÂÂÂÂ}

    ÂÂÂÂ// iterate through the 11 data segments
    ÂÂÂÂfor (i = 0; i < 11; ++i) {
    ÂÂÂÂÂÂÂÂoffset = be32 (&header[0x1c + i * 4]);
    ÂÂÂÂÂÂÂÂsize = be32 (&header[0xac + i * 4]);
    ÂÂÂÂÂÂÂÂif (offset + size > max)
    ÂÂÂÂÂÂÂÂÂÂÂÂmax = offset + size;
    ÂÂÂÂ}

    ÂÂÂÂreturn (max);
    }[/spoiler]

    I was asked for compiled files per PN.
    The compiled files and the sources are always available. See http://wiimm.de/wwt/ for details.

    @giantpune
    thanx for info.

    wit EXTRACT is now ready. I have compared the output with "yso" and "wii-scrubber" and all seems ok.
    wii-scrupper only creates the additionally file "banner.tpl". What's that?

    @giantpune
    The code example helped my to save time. Thanx again.

    @nicksasa
    Do you know that "yso" have a problem when extracting "ALL PARTITIONS"?
    All partitions are extracted to the same directory and some files of prior partitions are overwritten.

    my guess about banner.tpl is that it is only for gamecube games. there is a certain chunk of the opening.bnr for GC games that you can read and slop a header on and it will be a tpl.
