0.83.9

  • Physical CD drives are now mountable in SDL2 builds
    just like SDL1 builds, so commands like "MOUNT -CD"
    should work in both SDL1 and SDL2 builds. Some code
    is adopted from the SDL2_CDROM library. (Wengier)
  • Implemented file locking support for mounting disk
    image files so that you cannot mount the same disk
    image files in read/write mode at the same time as
    this can cause possible disk corruptions. A config
    option "locking disk image mount" is added to the
    [dosbox] section which when set to false (or if the
    user mounts the image files read-only) will bypass
    the locking of image files. Also improved the DOS
    file locking function, which can be disabled by
    setting "share=false" in [dos] section. (Wengier)
  • Implemented PhysFS support so that you can mount
    archives (e.g. ZIP/7Z) as drives in read-only mode,
    e.g. "MOUNT C TEST.ZIP" or "MOUNT D FILES.7Z". Some
    code is ported from a custom DOSBox fork. The menu
    option "Mount an archive file (ZIP/7Z)" is added to
    Drive menu to mount archives as Drives. (Wengier)
  • INT 13h now obeys the "hard drive data rate limit"
    setting, using the same disk I/O delay code as
    INT 21h file I/O. [Issue #2039]
  • Linux/X11 SDL1 builds: Combine window move/resize
    into one call if possible, and not during window
    manager hints, to avoid resize problems with the
    XFCE 4.14 platform.
  • Added menu option "Create blank disk images..."
    (under "DOS" menu) to create blank floppy or hard
    disk images of a common disk size, including 360KB,
    400KB, 720KB, 1.2MB, 1.44MB and 2.88MB for floppy
    disk images and 250MB, 520MB, 1GB, 2GB, 4GB and 8GB
    for hard disk images. The 1GB option (-t hd_1gig)
    is also added to IMGMAKE command. (Wengier)
  • The Configuration Tool will now be centered within
    the DOSBox-X window for a better looking. (Wengier)
  • Added config option "synchronize time" in [dosbox]
    section which when set to true will allow DOSBox-X
    to automatically synchronize the date and time with
    the host system, unless you manually change date
    and/or time. A menu option "Synchronize host date/
    time" is added to the DOS menu. The function uses
    IRQ0 handler; it will not work in PC-98 mode nor if
    the timer isn't running at the standard 18.2Hz tick
    rate, as any other rate does not make sense and
    will cause only jitter and error. Also fixed two
    Demoscene entries sl_fokus and sl_haloo which use
    BIOS_TIMER with a faster hardware tick rate.
  • Added config option "showdetails" which when set to
    true enables the menu option "Show FPS and RT speed
    in title bar" at start. It is equivalent to -showrt
    and -showcycles command-line options. (Wengier)
  • Improved compatibility with Watcom C++ 2.0 when
    long filename (LFN) support is enabled. (Wengier)
  • Added support for starting DOSBox-X in a specific
    display on a multi-screen setup (Windows builds as
    well as Linux/macOS SDL2 builds). A config option
    "display" is added to the [sdl] section that users
    can specify a display for the DOSBox-X window to
    start. The option can be combined with the existing
    "windowposition" config option to specify the
    position on the specified display/screen. (Wengier)
  • DOSBox-X will now pop up a message box to inform
    the user when a Direct3D pixel shader is loaded
    from the menu on the Windows platform. (Wengier)
  • Extended serial (COM) ports from COM1-COM3 to COM1-
    COM9 in the [serial] section. The config options
    serial4-9 are advanced options. You can optionally
    specify base addresses for any serial ports. When
    the "file" option is used, you can additionally
    specify a program to open the file with "openwith"
    option. If the specified program cannot be executed
    due to some problem, DOSBox-X will try to start a
    program as specified with the "openerror" action,
    or it will show an error. For both serial (COM) and
    parallel (LPT) ports options, the program commands
    can be quoted with double quotes, or with single
    quotes if the "squote" option is added. (Wengier)
  • Extended parallel (LPT) ports from LPT1-LPT3 to
    LPT1-LPT9 in the [parallel] section. Config options
    lpt4-9 are advanced config options. You can also
    optionally specify base addresses and IRQs for
    these ports. The parallel1-9 config options are
    enhanced to allow the generated files to be started
    with the specified action: "openpcl" to start a
    program to open the file if the print output is
    detected to be PCL; "openps" to start a program if
    the print output is detected to be PostScript (PS);
    "openwith" to start a program otherwise. If you'd
    like to specify parameters then be sure to properly
    quote the string(s). Furthermore, if any of the
    specified program(s) cannot be executed, DOSBox-X
    will try to start a program as specified with the
    "openerror" action, or show an error. (Wengier)
  • Added "openwith" and "openerror" config options to
    [printer] section to start the specified program to
    open the printer output file. The [printer] section
    also accepts "fontdir" option where you can change
    the path ("FONTS" by default) where the printer TTF
    fonts (including courier.ttf, ocra.ttf, roman.ttf,
    sansserif.ttf, script.ttf) are located. If no TTF
    font can be found (either from the custom path or
    system path) for printing, the internal TTF font
    for the TTF output will be used. (Wengier)
  • Added read-only options to the Drive menu to mount
    host folders/drives or image files to the specified
    drive letter in read-only mode. (Wengier)
  • You can now use a single mapper file for both SDL1
    and SDL2 versions of DOSBox-X! The new mapper file
    will be divided to sections [SDL1] and [SDL2] for
    both versions. The mapper file can be specified
    with the mapperfile config option, or you can set
    the mapperfile_sdl1 and mapperfile_sdl2 config
    options to override mapperfile option. (Wengier)
  • Added -defaultmapper command-line option which will
    use default key bindings for the mapper. (Wengier)
  • The menu functions "Load mapper file", "Quick edit
    mode", "Stop clipboard pasting" and "Display state
    information" have been added to the key mapper so
    that you can now define your own shortcut keys to
    activate these functions. (Wengier)
  • The default shortcuts for the "Copy to clipboard",
    "Paste from clipboard", and the "Reset window size"
    functions are now Ctrl+F5, Ctrl+F6 and Host(F11/F12)
    +BackSpace respectively. (Wengier)
  • Added ttf.fontbold, ttf.fontital, and ttf.fontboit
    config options so that you can specify actual bold
    italic, and bold-italic TrueType fonts for use with
    the TTF output that will render the bold, italic,
    and bold-italic text styles using the actual TTF
    fonts (e.g. consolab, consolai, consolaz instead of
    consola) instead of making the original TTF font
    bold, italic, bold-italic automatically. (Wengier)
  • DOSBox-X now supports the use of arrow keys (left,
    right, up, down, home, end) to select and copy text
    to the host clipboard in addition to a mouse button
    (subject to the specified key modifier, or use the
    QuickEdit function). The arrow keys will move the
    selections; press Home key to start the actual text
    selection and End key to end text selection and to
    copy to the clipboard; press ESC key to cancel text
    selection. Set config option "clip_mouse_button" to
    "arrows" to enable it, or select it from "Shared
    clipboard functions" menu group. (Wengier)
  • You can now press the key combination Ctrl+Tab in
    the shell to see a list of files/directories that
    can be completed by the Tab completion. (Wengier)
  • Added SETCOLOR command to view or change the text-
    mode color scheme settings. Also fixed the color
    palette for the TTF output. (Wengier)
  • Separated "TTF options" menu group that contains
    TrueType font (TTF) related menu options from the
    "Text-mode" menu group in "Video" menu. (Wengier)
  • The "Show menu bar" option now appears in system
    menu of the Windows SDL2 build too. (Wengier)
  • If a language file fails to load, DOSBox-X will now
    show a warning dialog instead of exiting. (Wengier)
  • The option "clip_key_modifier" now accepts values
    like "ctrlalt", "ctrlshift", "altshift". (Wengier)
  • Fixed 2D texture not showing for 3dfx games in the
    Glide passthrough mode. (Wengier)
  • Fixed the mouse sensitivity menu option (under the
    "DOS" menu) not working. (Wengier)
  • Fixed the color palette problem when switching to
    graphic mode from mono mode. (Wengier)
  • Fixed full-screen TTF output may not fully cover
    the background screen in Linux. (Wengier)
  • Fixed that lines starting with "%" in [autoexec]
    section are being ignored. (Wengier)
  • Fixed issues with building the code with original
    MinGW using the ./build-mingw script. (Wengier)
  • Fixed option "output=ttf" not working properly with
    -startui/startmapper command-line option. (Wengier)
  • When the mouse is captured, the title bar will show
    the shortcut to release the mouse. (Wengier)
  • IMGMOUNT now assumes the ISO type for .GOG/.INS
    files (which are equivalent to .CUE/.INS files)
    if no type is specified by the user. (Wengier)
  • Improved the dynamic core including the way its
    cache is allocated and to support dual mapping.
  • The FREECG98.BMP file (for PC-98 mode) is now
    rendered based on a unifont_jp TTF font instead
    of UnifontFullMediumMono.ttf. (roytam1)
  • Added support for automatic switching from TTF
    output to another output in PC-98 mode, allowing
    Windows 3.1 to run in this mode. (Wengier)
  • Added OPL3Duo support, which passes OPL3 output
    to an OPL3Duo Arduino board with a specific
    configuration if desired. Set the config option
    "oplemu=opl3duoboard" to use it. (josephillips85)
