    GPD Editors

    It seems all the "Devs" on this site don't know much about the format of GPD Files, You cant treat them like static saves.
    (You should also stop treating STFS files like the base block is always the same, it rarely is)

    The GPD(XDBF) format is the best documented and easiest Xbox format to handle.
    It is made up of 3 sections:
    The header,
    The tables(2 tables),
    And the raw binary data.

    I'm not going to write out the format, as free60 has it almost completely correct.
    But I'm going to tell you stop to stop treating them like static files, show you how to handle them, and give you some basic code, for reading the tables and returning the offsets.

    Games have only have direct access to the setting records, they can have a number of settings, but only upto 3 worth modding,
    1676165119(0x63E83FFF)
    1676165118(0x63E83FFE)
    1676165117(0x63E83FFD)
    They are the binary settings, they don't have to exist, and they cant be over 1024 bytes, but the first 24 bytes are not used by the game.

    You can view this quick XDBF class that I made for 360 haven on git hub,
    Its just a lite class to read and get offsets for records,

    init and reads the header and tables,
    Code:
    XboxClasses.XDBF.XDBF XDBF = new XboxClasses.XDBF.XDBF("C:\\Path\\To\\File\\.gpd");
    Two exceptions
    XboxClasses.XDBF.Exceptions.InvalidFileMagic - The file isn't valid, Its not a gpd
    XboxClasses.XDBF.Exceptions.InvalidVersion - The gpd version is incorrect, the only public version is 65536

    Get the setting offset
    Code:
    XDBF.IO.Postion = XDBF.GetSettingOffset(1676165119) + 24;//24 is the setting header, not used by the game
    One exception in GetSettingOffset
    XboxClasses.XDBF.Exceptions.SettingNotFound - the setting is not in the table.

    Then you can just read the from the IO like normal
    Code:
    XDBF.IO.Reader.ReadInt32()
    The IO is endian(big by default)
    Code:
    XDBF.IO.IsBigEndian = true;//>.< true = big, false = little
    Write
    Code:
    XDBF.IO.Writer.WriteInt32(0);
    Close
    Code:
    XDBF.IO.Stream.Close();
    Alert I really don't care if you use my code, It was quickly done, or if you give credit, but please, stop releasing the shitty tools that you just point a io to a static offset in GPDs

    Nicely said! Now let's see if any of the "Devs" will follow.

    Re: GPD Editors

    first of... this thread should be placed in c# sources/classes.

    second ... devs that handels gpd's as static binary would not be able to use your class... why ?! because they simply cant...

    i doubt the most devs dont know how to handel gpds...
    dont get me wrong though , u did great in posting this , just it wont change a lot... jizza posted his XDBF class along with a application to parse and read out all gpds entries... but didnt see anyone use it.

    Programming is 10% science, 20% ingenuity, and 70% getting the ingenuity to work with the science.

    ~~~~~~~~~~~~~~~~~~~~~~~~~

    Programming is like sex:
    One mistake and you have to support it for the rest of your life.

    Didn't even know Jizza made that... I don't like/try to make GPD editors. Their easier to just hex than use a tool in my opinion. A lot easier than modding a save as well... unless you have no idea on what your looking for in the GPD

    The stuff that I posted before is really old. The XDBF class was just an example of the information posted on free60. I also posted Hex Workshop bookmarks for XDBF and XContent for those who can't code but want to learn the file systems so they can h4x...
