    This file describes mymc, a utility for manipulating PlayStation 2
    memory card images as used by the emulator PCSX2. Its main purpose is
    to allow save games to be imported and exported to and from these
    images. Both MAX Drive and EMS (.psu) save files are fully supported,
    however save files in the SharkPort/X-Port and Code Breaker formats
    can only be imported and not exported. In addition to these basic
    functions, mymc can also perform a number of other operations, like
    creating new memory card images, viewing their contents, and adding
    and extracting individual files.

    A simple, hopefully easy to use, graphicial user interface (GUI) is
    provided, but it's limitted to only basic operations. More advanced
    opterations require the use of a command line tool. To install mymc,
    unpack the downloaded ZIP archive to a new directory on your machine.
    You can then run the GUI version of mymc by openning that newn
    directory with Windows Explorer and double clicking on the "mymc-gui"
    icon. To make it easier to access, you can drag the "mymc-gui" icon
    to either your Desktop, Start Menu or Quick Launch toolbar. Make sure
    if you do so, that you create a shortcut to "mymc-gui.exe". If you
    copy the file instead, the program won't work.

    The command line utility can be invoked from the Windows Command
    Prompt by using the "mymc" command. The executable "mymc.exe" and
    number of support files and these file must kept together in the same
    directory. To run the command you need to either add the directory
    where you unpacked the distribution to your PATH or type the full
    pathname of the executable. For example if you unpacked mymc to a
    directory named "c:\mymc" you need to enter "c:\mymc\mymc.exe" to run
    the program.

    The second important thing to note is that mymc is only "alpha"
    quality software. This means that has is been released without
    extensive testing and may be unreliable. While it works fine for me,
    the author, it might not work as well for you. For that reason you
    should be careful how you use it, and prepared for the eventuality of
    it corrupting your save game images or producing garbage save files.
    If you're worried about this, one make things safer is to use two
    memory card images. Use the first image to load and save your games
    with under PCSX2, and the second image to import and export saves
    games using mysc. Then use the PS2 browser to copy files between two
    card images.


    The GUI for mymc is should be easy to use. After starting mymc, you
    can select the PS2 memory card image you want to work with by
    selecting the "Open" command by pressing the first button on the
    toolbar. You can then import a save file clicking on the Import
    toolbar button. To export a save files, first select it and then
    press the Export button. You can delete a save file permanently from
    your memory card, by selecting the "Delete" command from the File

    Do not try to use mymc to modify a memory card image while PCSX2 is
    running. Doing so will corrupt your memory card.


    The basic usage template for mysc is "mymc memcard.ps2 command". The
    first argument, "memcard.ps2" is the filename of the memory card image
    while "command" is the name of the command you wish to use on the
    image. So for example, assuming you've installed mymc in "c:\mymc"
    and you've installed PCSX2 in "c:\pcsx2" you could enter the following
    command to see the contents of the memory card in the emulator's slot

    c:\mymc\mymc c:\pcsx2\memcards\Mcd001.ps2 dir

    You would see output something like this:

    154KB Not Protected SYSTEMDATA

    BADATA-SYSTEM Your System
    5KB Not Protected Configuration

    BASLUS-20488-0000D SOTET<13>060:08
    173KB Not Protected Arias

    7,800 KB Free

    This is the simple "user friendly" way to view the contents of a
    memory card. It displays the same information you can see using the
    PlayStation 2 memory card browser. On the right is name of each save,
    and on the left is the size and protection status of the save. Also
    on the left is one bit of information you won't see in the browser,
    the directory name of the save file. PlayStation 2 saves are actually
    a collection of different files all stored in a single directory on
    the memory card. This is important information, because you need to
    know it to export save files.

    As mentioned above, if you know the directory name of a save, you can
    export it. Exporting a save creates a save file in either the EMS
    (.psu) or MAX Drive (.max) format. You can then transfer the save to
    real PS2 memory using the appropriate tools. You can also send the
    saves to someone else to use or just keep them on your hard drive as a
    backup. The following command demonstrates how to export a save in
    the EMS format using mymc:

    c:\mymc\mymc c:\pcsx2\memcards\Mcd001.ps2 export BASLUS-20448-0000D

    This will create a file called "BASLUS-20448-0000D.psu" in the current
    directory. To create a file in the MAX format instead, use the export
    command's -m option:

    c:\mymc\mymc c:\pcsx2\memcards\Mcd001.ps2 export -m BASLUS-20448-0000D

    This creates a file named "BASLUS-20448-0000D.max". Note the "-m"
    option that appears after the "export" command.

    Importing save files is similar. The save file type is auto-detected,
    so you don't need use an "-m" option with MAX Drive saves. Here's a
    couple of examples using each format:

    c:\mymc\mymc c:\pcsx2\memcards\Mcd001.ps2 import BASLUS-20035.psu
    c:\mymc\mymc c:\pcsx2\memcards\Mcd001.ps2 import 20062_3583_GTA3.max


    - To get general help with the command line utility use the "-h"
    global option (eg. "mymc -h"). To get help with a specific
    command use the "-h" option with that command (eg. "mymc x
    import -h"). In this later case, you need to specify a memory
    card image file, but it's ignored and so doesn't need to exist.

    - Both executables in the Windows version, "mymc.exe" and
    "mymc-gui.exe" do the same thing and support the same options.
    The difference is that "mymc" is console application, while
    "mymc-gui" is a Windows appliction. Currently, using "mymc"
    to start the GUI will result in a fair amount debug messages
    being printed that are normally not seen "mymc-gui" is used.

    - It's possible to use mymc create images that are bigger (or
    smaller) than standard PS2 memory cards. Be very careful if you
    do this, not all games may be compatible with such images.

    - The bad block list on images is ignored. Since memory card
    images created with either PCSX2 or mymc won't have any bad
    blocks, this shouldn't be a problem unless you've somehow
    extracted a complete image from a real memory card and expect to
    copy it back.

    - The PS2 only uses at most 8,000 KB of a memory card, but there
    is actually 8,135 KB of allocatable space on a standard
    error-free memory card. The extra 135 KB is reserved so that
    memory card with bad blocks don't appear to have less space than
    memory cards with fewer or no bad blocks. Since there are no
    bad blocks on memory card images, mymc uses the full capacity
    provided by standard memory cards.


    The "source code" distribution of mymc is provided for users of Linux
    and other non-Windows operating systems. It uses the same Python code
    that the Windows distribution is built with (using py2exe) and
    supports all the same functionality. One big difference is that the
    Windows DLL "mymcsup.dll" is not included and as a result compressing
    and decompressing MAX Drive saves will be as much as 100 times slower.
    The GUI mode is hasn't been extensively tested on non-Windows systems,
    and the 3D display of save file icons requires the DLL. The Python
    source version should support big-endian machines, but this hasn't
    been tested.
    Change log:
    MYMC 2.6.g2 2015-05-01
    - Added a Folder Analysis feature, to find where all your games are.

    This will go through all VMCs in a folder, collect all the gamesave info, and provide a window with the full summary.
    The report can be saved to a file.
    Pick any VMC file in the folder, the entire folder will be analyzed.
    Does not recurse into subfolders.

    - Still does not support icon graphics.

    MYMC 2.6.g1 2015-04-12
    This is a minor edit to the original tool by Ross Ridge.
    - Version 2.6.g1 adds the ability to MYMC to let it recognize the VMC format
    of PS2 memory cards, as supported by OPL 0.9.2
    - Default extension of these files is .bin
    - MYMC open file dialog will now allow .bin and the original .ps2 files to be opened.
    - .bin files do not use and do not store extra ECC data that is included in the .ps2 format. So the data
    files are slightly smaller.
    - Memory card Files are automatically rewritten / saved back to the original file opened, in it's
    original format, whenever the program is closed or another file is opened.

    BACKUP your files FIRST!!! This program edits files "in place."
    So work on a backup copy.
    If you don't, then surely that will be when this all catastrophically fails and deletes all your saves.
    SAVE a copy of your memcard first, and only open the copy to test out. possibly in whole separate folder, or another drive, on a PC in someone else's house, etc.
    There is NO option to "SAVE AS" a different file within the program yet.
    There is also NO option to exit without saving.

    So BACKUP!

    Note: The original work is substantial and I only have a partial understanding of it.
    I have only attempted to extend its use to benefit OPL users with some tiny changes.
    My testing is limited, and focused on the VMC .bin format, since that is what I use.

    possible issues:
    - don't have a way to save cross-format yet. i.e. "Save AS", and choose other format, or even to save as
    a separate file to avoid overwriting the original.

    - My creation of EXE from the python source doesn't have the hooks worked out yet to display the icon graphics.
    you may get a warning on startup that the DLL is not available. It does try to continue to operate without
    showing the graphics.
