DOSBox-X Beta (2018/05/18) is released. DOSBox-x is a branch of DOSBox v0.74. DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, joystick, modem, etc., necessary for running many old MS-DOS games that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows XP, Windows Vista, Linux and FreeBSD.

DOSBox-X Changelog:
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
