DOSBox-X release 0.82.7 2018-06-01 13:05

0.82.7

  • Mac OS X builds now honor showmenu=false by leaving the
    stock SDL menu in place at startup.
  • Default minimum MCB free/base is now 0x100, to sidestep
    unknown unstable DOS application behavior when DOS
    applications are loaded at around segment 0x800.
    This also puts DOSBox-X at parity with the base memory
    behavior of DOSBox SVN.
  • Add dosbox.conf option to set Sound BIOS enable
    bit in non-volatile RAM (PC-98) that tells older
    PC-98 games the FM card is present (Yksoft)
  • BOOT updated to boot D88 except for 2D format which
    is generally used by PC-88 disk images.
  • Added D88 disk image support
  • CMake files added (Aybe)
  • PIC timing updated to use "double" float type for
    more precision, but as a typedef for future support
    as a compile time option.
  • Removed geometry checks from INT 1Bh FDC functions,
    to allow non-uniform disks to work.
  • MinGW builds now allowed to use Direct3D.
  • Direct3D output fixed to use the same texture
    coordinate, window fitting, and positioning
    logic as OpenGL.
  • Update zlib and libpng libraries in-tree.
  • Fixed VFD disk image support to correctly signal
    failure to detect geometry, to avoid divide by
    zero crash with FAT driver.
  • showmenu= now taken into consideration whether to
    show the menu bar at startup
  • Fixed get_item() E_Exit crash if menus asked to
    show from dosbox.conf
  • SDL drawn menus fixed to integrate with Direct3D
    output on Windows.
  • PC-98 mode can now boot floppy disk images where the
    boot sector is 128 or 256 bytes/sector despite
    track 1 and higher having 1024 bytes/sector.
  • General codebase cleanup, compiler warning cleanup.
  • Enable XInput support on Windows (Aybe)
  • Fixed SDL drawn menus to use std::vector properly,
    not to hold onto iterators while resizing the vector
    and popping things off the top.
  • PC-98 INT 1Bh "read id" floppy disk call fixed to
    cycle through sector numbers. Some bootable PC-98
    games use "MEGDOS" which polls this BIOS call before
    attempting to read the disk. If the sector numbers
    never cycle, "MEGDOS" will not attempt to read the
    disk.
  • Fixed bug that prevented some menu options (such as
    "aspect ratio") from working if still in the BIOS or
    booted into a guest OS.
  • PC-98 mode fixed to ignore "mainline compatible mapping".
    That mapping mode refers to DOSBox SVN which never
    supported PC-98 mode anyway.
  • Fix PC-98 INT 1Bh "test read" call, which then allows
    "cherry bomb" to run.
  • Remove geometry checks in PC-98 INT 1Bh BIOS call, so
    that FDD images with odd sector sizes can work.
  • ROM BIOS now automatically occupies E8000-FFFFF instead
    of F0000-FFFFF when in PC-98 mode.
  • Most 128 byte/sector FDD images appear to jump to
    E800:0002. I'm guessing that's ROM BASIC, so add a
    callback at that location to catch these boot disks
    and show a message instead of allowing the boot
    sector to jump to nothing and crash.
  • PC-98 BOOT fixed to check for and support booting from
    FDD images where track 0 contains 128 byte/sector
    boot sectors.
  • PC-98 INT 1Bh support fixed to support reading/writing
    sector sizes other than the one sector size reported
    by the image. It is now possible to read the other
    sector sizes from an FDD/VFD image.
  • Fixed somewhat serious bug that, when compiled against
    Microsoft C++, causes the AVI writer to use the 32-bit
    lseek() function instead of the 64-bit lseek64() function.
    Prior to this fix, AVI captures would begin to corrupt
    themselves after growing past 2GB in size.
  • Cleanup code, fix compiler warnings, typecast problems,
    C/C++ conformance problems as reported by GCC 4.8,
    GCC 7.3.0 (MinGW), Visual Studio 2017, and Clang/LLVM
    on Mac OS X.
  • FM Towns machine type stub, for anyone interested in
    forking DOSBox-X to implement FM Towns emulation.
  • Code cleanup, refactor, according to compiler warnings.
  • SDL drawn menus fixed to copy Direct3D backbuffer to
    the SDL surface when popup occurs. This allows the
    menus to overlap the Direct3D display correctly.
  • Fixed Direct3D output so that when composing the next
    frame in the backbuffer, it also copies the SDL drawn
    menu from the SDL surface in order to keep it on
    screen.
  • Direct3D output updated to follow SDL clip rectangle
    struct, in the same exact manner as the OpenGL output.
    This also permits the Direct3D output to correctly size
    itself and leave space at the top for the SDL drawn
    menus.
  • Fixed dynamic core entry point to push/pop EBP because
    debug builds need the compiler to track the stack frame.
  • Updated in-tree zlib and libpng libraries to the latest
    provided by both projects.
  • Fixed VFD (FDD) disk image support to signal to FAT driver
    properly an error if it could not determine a geometry.
  • Fixed code breakage with SDL2 that prevented compilation
    with Munt (MT32) emulation enabled. SDL2 builds now allow
    MT32 emulation.
  • Mac OS X builds now compile against the in-tree zlib and
    libpng libraries for consistency.
  • MinGW builds now compile against the MinGW provided zlib
    and the in-tree libpng library for consistency.
  • Enabled MinGW builds to use Direct3D and Direct3D shaders.
  • Added code to auto-detect the VirtualBox display driver
    in Windows build, because OpenGL output doesn't work
    in Windows XP under VirtualBox. The change will switch
    the default output to "surface" if VirtualBox is detected,
    else will retain the "opengl" default. This change applies
    only to MinGW builds and not HX DOS or main VS2017 builds.
  • Added PC-98 INT DCh emulation for function call that
    writes a char to the screen, allowing Eve Burst Error
    to clear the function row
  • Added command line option to allow skipping the 1-second
    wait in the BIOS startup screen.
  • SDL2 builds now support use of the SDL drawn menu with
    a touchscreen device.
  • Fixed up SDL2 support code to compile correctly on
    Mac OS X.
  • Fixed up SDL2 compilation to automatically use the
    SDL2 library on the system, or if that is not available,
    use the SDL2 library in-tree. There are no plans to make
    modifications to the in-tree SDL2 code.
  • Added code to read and discard OpenGL error code before
    creating font texture, to avoid false failure handling.
    This fixes font rendering on Windows MinGW builds when
    output=opengl.
  • OpenGL SDL drawn menus fixed to ensure the menu contents
    have been redrawn at least twice. One for each OpenGL
    buffer because DOSBox-X uses the double-buffered mode.
  • SDL drawn menus implemented for output=opengl. The menu
    bar in Linux builds is now available in OpenGL mode.
  • SDL drawn menus fixed to redraw only when state changes,
    and to clean up menu drawing code.
  • US keyboards can now enter the "Ro" key in PC-98 mode.
    Default binding is set up to map the Windows Menu key
    as Ro in PC-98 mode.
  • VGA option change code fixed to trigger scaler redraw
    correctly. Changing video modes or changing between
    8/9-pixel VGA text no longer leaves artifacts on the
    screen.
  • Added code to force redrawing additional frames when
    output=opengl, in order to correct a bug with Linux/X11
    and MesaGL where the first OpenGL buffer swap after
    SDL_SetVideoMode() is misplaced when the window size
    changes.
  • Renderer SSE line comparison fixed to use correct sizeof()
    of the integer type during compare.
  • Renderer fixed not to use SSE and non-SSE line comparision
    at the same time, if SSE was enabled at compile time.
  • Fixed in-tree SDL 1.x library to allow DOSBox-X to disable
    auto-refresh of the window in Linux/X11 after SDL_SetVideoMode
    to prevent visible flickering when resizing the window.
  • Conditional support for Direct3D (9) output enabled for
    MinGW builds, if the MinGW headers are available (yksoft1).
    Option is disabled by default.
  • Configuration GUI dialog box widened to accomodate buttons
    that were previously cut off on the right.
  • Replace E_Exit() with LOG_MSG() for key codes from the mapper
    that a keyboard scan code generator does not recognize. This
    fixes E_Exit() crashes if typing certain keys on a Japanese
    keyboard with no equivalent in IBM PC/AT mode.
  • Added code to double the size of the menu and menu items if
    the window is 1280x800 or larger, for users with high
    definition laptop displays and screens.
  • Enforce minimum window size of 640x400 if the menu bar is
    visible and DOSBox-X is drawing them, to make sure the menus
    are accessible on screen.
  • Removed auto-scalar-size code when output=surface that was
    causing problems when resizing the window.
  • Do not show "screenshot" menu item if screenshot support not
    available at compile time.
  • Remove "always on top" for anything but Windows at this time.
  • Disable "Show debugger" option on Linux and Mac OS X if no
    console attached to STDIN/STDOUT/STDERR.
  • Disable "Show console" option on Linux and Mac OS X since
    the console is not under our control.
  • Windows "Always on top" fixed to remember selection and
    enforce it between SDL_SetVideoMode and fullscreen entry/exit.
  • Windows builds fixed NOT to change window Z-order on the
    screen when updating the window on SDL_SetVideoMode.
  • HX DOS builds fixed to keep window maximized at all times
    to fill the otherwise unused space on the screen since
    HXGUI only supports one window.
  • Menu framework support for any other platform (including
    Linux) added. The menus are drawn by DOSBox-X itself
    using the 8x16 VGA font. This also gives SDL 2.x builds
    a working menu. These menus are used if no other platform
    specific menus are available. These menus are NOT AVAILABLE
    at this time if output=opengl.
  • Cycle count edit dialog box fixed to immediately place
    keyboard focus in the text field, and to process
    ENTER and ESCAPE keyboard input as OK and CANCEL
    button input. You can type a new cycles count without
    having to click on the text field first.
  • Menu framework and mapper fixed so that menus always
    reflect the mapper binding in the menu.
  • Windows SDL 1.x fixed async hack to properly destroy
    and shut down the parent window again.
  • Fixed output=opengl crash on Mac OS X.
  • Menu framework support for Mac OS X NSMenu objects added.
    This gives DOSBox-X the same useful menu on Mac OS X
    instead of the useless default menu SDL 1.x offers.
  • Menu framework support for Windows win32 menu resources
    added. The Windows menu is now generated at runtime,
    the static IDR_MENU resource is no longer used.
  • New platform independent menu framework added. Menus
    that were once Windows-only are now available on
    any other platform including Linux and Mac OS X.
  • In-tree SDL 1.x library fixed to #define a special
    variable that the code now requires to compile
    SDL 1.x builds. The option to use your host SDL 2.x
    library is left open.
  • C++11 is now mandatory to compile DOSBox-X

The preview of the XInput-enabled build is shipped as a separate archive, recommended for Xbox 360 and Xbox One controller owners wishing to use joystick input.
