I have updated Atari800win at the usual home page,

http://www.cris.com/~Twist/atari800win

Atari800Win is an Atari 8-bit emulator for the Win9X/NT environment.
It emulates the Atari800, 800XL, XE series, and 5200 systems.

Here is what is new in version 2.4:

09-08-98    Ver 2.4 - large update, some beta features
  * A request: I am looking for an image of the 8-bit Epyx game
    "Hellfire Warrior". I'm not sure if it was available for the
    Atari, but it was for the Apple][. I own this game, but only have
    the TRS-80 disk image.If you can help, please e-mail
    rich@cstone.net

  * Big feature: support for save states (also known as "snapshots").
    You must have ZLIB working (the DLL supplied with Atari800Win must
    be in the path) to use this. Saved states saves _everything_ about
    your Atari itself, the entire contents of memory, where you are in
    a program, etc. A save state does NOT save your display, input, or
    sound settings. When you load a state save, the Atari will be
    paused on a black screen. Hit F9 to start the saved state. Saved
    state file sizes will vary based on the machine type and what it
    was doing / had loaded.

    Use the File menu to access the Load/Save state features. There
    are two types of save: normal and verbose. Verbose is ONLY
    necessary if you have patched ROMS that somebody else wouldn't
    have. Verbose saves are larger.

    Save states should be considered a somewhat beta feature. Changes
    might affect the format as other Atari800 ports adopt it, making
    the current format obselete. Keep in mind that even if you
    snapshot a program it may still want to access the disk later; and
    save states do NOT save disks. If you know a program accesses the
    disk, you will have to keep the disk handy with your save state to
    resume later. Save state are machine independent; they will be
    useable on other ports of Atari800.

  * Machine language routines here and there; small speed difference.
    I spent considerable time rewriting some large sections in
    assembly, and found there was little speed increase in them even
    when heavily optimized.I'll continue investigating asm for things
    like Antic though.
  * Atari crashes are much less dramatic now, as you don't have to
    exit Atari800Win. The screen will simply go black, you then have
    the opportunity to change settings, and there is a new
    Atari/Restart menu option to fire the machine up again (Ctrl-F5
    will also work).
  * Added 512x384 mode. Should help those on slow machines without 320
    modes. Shows full overscan and on most cards has that "scanline"
    feel.
  * Completely rewrote the keyboard handler, many changes include:
    - A few layout changes; see README.TXT
    - Insert/Delete work correctly (char normally, line when shifted)
    - Clear character now on the Windows Home key
    - Option/Select/Start can be held down in combinations,fixes some
      demos
    - When holding a regular key, pressing then releasing a second key
      will have no effect (the first key will stay held).
    - Hold down a regular key, hold down a second. Release the first
      key.The Atari will register the second key as being held down
      after exactly 1 frame of no keys.
    - F1-F4 exist only for XL, returns no keyboard code for other
      machines.
    - Help returns no code for non XL/XE machine
    - With CTRL + SHIFT held, the following keys do NOT work on
      purpose:
      J K L ; + * Z X C V B F1 F2 F3 F4 and HELP
    In many cases the new behavior my seem more limiting than before;
    but it is now highly accurate compared to the real hardware. Many
    hours in testing with a real XE back this up. Since there is
    considerable new code there may be an errant key here or there;
    please e-mail me if you find keyboard oddities (or if you find
    things fixed!)
  * Keyboard templates option added (Options/Keyboard.. menu). This is
    a complicated feature for expert users, consult the README for
    details.Do not mess with it if you don't understand the purpose.
    Briefly, It allows you to remap almost the entire keyboard to
    anything you wish to define. Helpful for games that use whacked
    out directional keys like the Ultima series or if you want to
    exactly duplicate the Atari layout.
  * Keyboard joystick reworked. Now handles combination keys (numpad4
    + numpad8 = diagonal up/right). Ignores your Windows key delay /
    repeat settings and works right off the keystroke (instant
    feedback).
  * Checkbox for "use AGP memory", which controls whether a surface is
    allocated as "local video memory" in Ddraw terms. This is
    basically for DDraw windowed modes, and could be faster, musch
    slower, or no change on any particular card - you'll just have to
    try it and compare.
  * Fixed a problem with small graphics selector dialog used in 320
    modes.
  * All full screen modes clear their backgrounds.
  * Bolder, more ambitious icons, less filling but taste great. Any
    icon artists out there?
  * Machine type and speed shown in window title (status bar in full
    screen)
  * Finally remembered to add keyboard click. You will notice a slight
    delay between the keystroke and sound, can't be helped at present.
  * Fixed a display bug that had crept in when in windowed mode with
    the display partially off the desktop
  * If you exit while running full speed, the next time you launch
    sound
    will be (correctly) disabled until you switch back to normal speed
  * Pause shows paused text on Atari screen (for full screen modes)
  * Fixed crash bug that sometimes occurred changing artifacting
    modes.
