XM6 Pro-68k is an X68000 emulator for Windows. It is a derived from the venerable XM6, which was developed by PI.

(The X68000 was a high-spec Japanese computer billed as a personal workstation. It was powerful enough to run ports of contemporary arcade games without compromise.)

Originally the focus was on adding development/debugging features (hence the "pro" moniker), but more recently, the main goal has been improving the user interface and adding ease-of-use features, especially for English-language users. And people who use keyboard shortcuts.

It also strives to have the most accurate floppy drive emulation of any X68000 emulator.

Prominent general-interest additions/changes include:

  • Unicode support
  • fast-forward key (tilde)
  • zip and 7-Zip (.7z) archive support for floppy disk images and states files (see screenshots below)
  • many new keyboard shortcuts and menu commands; rewritten/expanded context-sensitive help
  • some input finagling so you can (mostly) type correctly with an American keyboard
  • on creation, SRAM will have Western-style features (e.g. backslash as directory separator)
  • original XM6 state file compatibility has been maintained (the Unicode edition can load but not create them)
  • quad-drive support and much more accurate floppy drive emulation
  • two new keyboard modes for playing games
  • semi-integrated notes about various X68000 games, updated frequently
  • an English-language manual (albeit not comprehensive)
  • a cheat finder and a corresponding cheating subsystem (still in development, however)
  • delta file support: disk image changes can be redirected to a separate file
  • the ability to download cryptographically signed updates (only when directed to do so by the user)
  • support for two simultaneous MIDI output sources: standard MIDI and RS-MIDI (needed for full Lodoss II support)
  • tons of other stuff that you likely won't realize unless you pore over both the manual and change log

    (It might seem pointless; XM6 is now so old that it's unlikely anyone will be comparing the two feature sets...)

    Automatic Installation

  • Download and extract the XM6 Pro-68k zip file (and move the contents somewhere suitable)
  • Double-click the batch file named "Download XM6 Pro-68k" to retrieve and extract the necessary packages from this site

    Optional: Shortcuts can be added or removed at any time. Simply run XM6 Pro-68k and open the Tools menu. The Install and Uninstall submenus can be used to add or remove links to the program. The desktop shortcut comes with a hotkey (Ctrl-Shift-X) to launch the program, although it might not register until your next log-in.

    You can check for (and download) updates by using the relevant menu item under the program's Help menu. Running the "Download" batch file again will also work.


    Manual Installation

    You will need 7-Zip (or a compatible program) to perform a manual installation. Download and extract the contents of each of the following packages into the same directory. If the packages extracted into separate directories, you must merge them into a single directory.

    XM6 Pro-68k.7z (modification date here)

    XM6 Pro-68k DLL Package Strongly recommended. Includes ZLIB1.DLL and CGROM.DAT.

    XM6 Pro-68k Web Package Optional. Enables downloading game notes and updates to the program.

    Note that the Automatic Installation above is essentially using the Web Package alone to download and extract the other packages; a manual installation is just a more challenging and less efficient method of accomplishing the same thing. If for some reason the Automatic Installation does not work for you, please report the problem so it can be fixed!

    The Web Package has been updated to remove a dependency on Normaliz.dll, which was found to be unavailable in certain older operating systems. It is not necessary to redownload it otherwise.


    Technical Support

    Support is available via email. There are no prerequisites at this time; you don't even have to bother reading the documentation first. Feature requests and bug reports are welcome. (If you do not report bugs, how do you expect them to be fixed?)

    Send your emails to gmail user name mijeto. It could take a few days (worst case weeks) to receive a reply, so please be patient.


    Other Emulators

    PI's new site has the original XM6 (circa 2006) and currently seems to be distributing Gimons' excellent XM6 Type G fork for some reason.



    Screen Shots



    This actually works now!
    (Without special hardware, I mean. You may need two MIDI devices installed but they can be soft synths.)



    If a disk image is recognized, icons will appear briefly upon insertion to let you know whether it is in the correct drive or not. (It's more complicated than that; please read the manual for details.) As the above example illustrates, one would be incorrect in assuming that the Disk labeled "II" should go into the second drive. The red arrow indicates that it actually belongs in the first drive (except when you are watching the intro, in which case it should not be inserted at all). The recently-used menus for the correct drives will be populated automatically to make it easier to move the disk.



    Multiple disk images contained within the same archive (.zip or .7z) are supported. Simply load the archive file as normal and then select a disk image (maximum of 16) from the menu. For even more convenience, drag and drop an archive while holding Alt to load it into both drives. Keyboard mnemonics are now available for files within archives to make switching disks even easier: simply press the corresponding letter when the menu is open.



    The above showcases XM6 Pro-68k after having loaded a 7-Zip archive containing 87 state files. The size of the archive is less than a megabyte! On my development machine, in debug mode, it took around half a second to load arbitrary state files from this particular archive, in the worst case.



    The software keyboard window now shows feedback for multiple input devices. Blue and green represent controller inputs. For example, the port-1 joystick's first button is represented by a blue '1' key and the axes are represented by the arrow keys. Keyboard keys are shown in red as normal.



    Up to 4 floppy drives are now supported. The TIMER and POWER indicators are replaced with FDD LEDs only when extra drives are attached. The extra drives are only shown in the pop-up menu, not the main menu, since most people do not need them. It's little more than a novelty, as very few games will take advantage of additional drives. (The game depicted in the screenshot above is a rare exception.)


    7-Zip Source Code

    You don't need this; it's just a licensing thing. No modifications were made: 7z1900-src.7z
