DOSBox-X

competition

As a fork of DOSBox, it retains compatibility with the wide base of DOS games and DOS gaming DOSBox was designed for. That said, it goes further, with a focus on accurate emulation of the hardware and many more ways to tweak and configure the DOS virtual machine. They believe that a better way to emulate the legacy PC platform is to give the user all the options they need to emulate everything from original IBM PC hardware with 64KB of RAM all the way up to late 90's hardware, whatever it takes to get that game or software package to run. Their goal is to eventually make DOSBox-X a complete emulation package that covers all pre-2000 DOS and Windows 9x based hardware scenarios, including peripherals, motherboards, CPUs, and all manner of hardware that was made for PC hardware of that time.

Most Recent Changes

  • FDC emulation now allows READ command to look for
    sector numbers that are out of range in order to
    support booter games that read out of range sector
    numbers as part of their copy protection.
  • Windows SDL1 window resizing fixed to avoid snapping
    and jumping issues when the window is sized down
    to the point the menu bar doubles or triples in
    height due to menu item wrapping.
  • FDC clear DMA terminal count automatically (with a
    warning printed to the log) at beginning of FDC
    read/write (PC-98 booter game Star Cruiser).
  • FDC DMA read/write failure now causes FDC to signal
    an error, and the debug output will say so.
  • FDC debug output now shows motor bits in the correct
    order, not backwards
  • CONFIG.COM and MIXER.COM are now registered only at
    DOS kernel startup, to resolve their disappearance
    after RE-DOS or guest system reset.
  • Some OpenGL cleanup and fixes for when compiling for
    Mac OS X Catalina.
  • Shell startup now prints the actual mapper binding
    (whatever it is) for the Host key instead of assuming
    F12/F11.
  • "Ro" key in PC-98 mode in the mapper interface now
    clarifies that it is Ro / _ since the shift state is
    the underscore.
  • Shell startup code fixed to show F11 for Windows and
    F12 for other platforms properly instead of always
    showing F11.
  • Added BOOT option --pc98-graphics to start up with
    graphics layer enabled in order to run HDI images
    using QMOUSE and games that expect NEC MOUSE.COM
    behavior of showing graphics layer on driver init.
  • BOOT now hides graphics layer on startup in PC-98 mode
    to reflect real hardware.
  • INT 33h mouse emulation now enables graphics layer
    on mouse startup and INT 33h AX=0 to imitate NEC
    MOUSE.COM behavior seen on real PC-98 hardware. This is
    needed for some Orange House games that assume this
    behavior, without which the graphics are invisible.
  • INT 33h define range functions now include separate
    range correction for text mode vs graphics mode.
  • Help sections in Configuration GUI have been improved,
    they are now easier to browse and read. (aybe)
  • CONFIG: added description for 'securemode' (aybe).
  • Integer properties are now correctly saved when
    they have been changed in configuration GUI (aybe).
  • Some scenarios with command history could display
    garbage characters from previous/next command (aybe).
  • Fixed all hard disk images created by IMGMAKE having
    VHD footers. (Allofich)
  • Windows Visual Studio solution: (aybe)
    cleaned and clarified project properties for projects
    removed configurations that didn't make sense
    fixed broken debugging
    consolidated to use single versions of SDK and IDE
    enabled faster builds (multi-processor compilation)
    fixed broken builds, e.g. ARM, ARM64
