Axis and Allies '98 Nvidia PATCHED


  • Axis and Allies '98 Nvidia/Vista PATCHED
    by AQRIT

    Axis and Allies has a drawing problem
    ( only the background is visible on screen )
    It occurs on systems using Vista and/or Nvidia graphic cards.

    Download the patcher from: www.aqrit.cjb.net

    Known Issues after patch:

    1. pressing ctrl+alt+del causes Ctrl to
          “stick” on. When you return to the game window
          be sure to tap the ctrl key! ( Group Movement Modifier )

    2. dice screen flickers once if any hits occur

    3. quit dialog button text drawn incorrectly

    FYI: some Vista users may not be able to run the Axis and Allies installer…
        I’d hate to be you.

    FYI: Computers with more than one CPU should
        set the process affinity mask to a single CPU
        this allows the cinematics to play.

    I’m guessing the problem with Axis and Allies
    drawing code is that the game doesn’t lock it’s surfaces before
    drawing to them…

    my patch does NOT fix this…

    instead my patch:
    sends all the drawing to address 00444B09
    unless the source is also the destination
    in which case it lets DirectDraw Blt it as normal

    Patch Info:
    Module: AxisAllies.exe (any version?)
    File Address: 00044AAB (VA: 00444AAB)
    Old Value = 3B D0
    New Value = 3B F5

    Quick hacking reference:
    0044771D  // call create DirectDraw 2 object
    004478E5  // call createSurface primary
    00443CEE  // call createSurface offscreen

    00444840  // sub draw
    00444FEO  // sub Blt the back to front (like a flip)
    00431CD0  // sub draw Main Menu

    // after the primary surface has been created then…
    [0x005CA720] + 0x98 = primary surface front buffer
    [0x005CA724] + 0x98 = primary surface back buffer
    [[[[0x005CA720] + 0x98]] + 14] == ddraw.Blt()

    It is possible to run in windowed mode if you hack it…
    I don’t know if there is a switch somewhere for it?
    ( and i haven’t tried this patch in window mode )

    ///////////////////

    I’d appreciate it if people mirrored my patcher
    ( which is half the size of this post )
    as it currently is hosted on a sketchy free site that
    doesn’t get indexed by search engines and
    can’t be reached at all using Firefox? 🙂
    if you do, post a link in this thread

    Good Luck, Have Fun!



  • BTW, hats off to you if this works widely.


  • AADrawPatch version 2.0 released

    www.aqrit.cjb.net (Internet Explorer only…)


  • version 2.1 released

    www.aqrit.cjb.net (Internet Explorer only…)


  • aqrit, thanks for all the patches. Any chance that you might have one for a dual processor soon? Sorry to ask for more when you’ve done so much already. Just had to ask since I miss this game so much since I had go to a new laptop.


  • v2.1 has been merged it into the Starter Pack at http://ewarzone.com/aa.html

    the original files are at:

    http://ewarzone.com/downloads/aadrawfix21.zip and
    http://ewarzone.com/downloads/aadrawfix21_src.zip

    Any chance that you might have one for a dual processor soon

    v2.1
    limits the game threads to a single cpu…
    having dual processors shouldn’t be an issue?

    can you describe the problem your having?
    not that I can think of any way to impove my patch at this time


  • @aqrit:

    version 2.1 released

    www.aqrit.cjb.net (Internet Explorer only…)

    Forgive my utter lack of computing skills, but I am trying the patch…after unzipping it, I try running it. It then gives me a message (“Version 2.1 yada Vista Users need permission…”) followed by the “Open” screen…only there is no file name to open. I am rather stuck.

    By the way, I’m on a 64-bit computer running Vista (big thumbs-down to both, but it’s my gf’s computer).


  • shimrod,

    you should be opening the games main exe ( AxisAllies.exe )

    if you can’t get it to work then use
    The Starter Pack at http://ewarzone.com/aa.html
    which is pre-patched
