Il s’agit d’un fork de DOSBox des plus intéressant, destiné à Windows Linux et MacOS et créé par Jon Campbell. Il possède une compatibilité excellente et met l’accent sur la précision d’émulation notamment en ce qui concerne l’émulation de Windows 3.x à ME. En outre il ajoute des améliorations en provenance d’autres builds comme DOSBox ECE avec l’émulation de la 3DFX en interne.

Les améliorations sont les suivantes:

IMGMOUNT now supports mounting a RAM drive (using -t ram) (Shane32)
Direct3D fullscreen aspect ratio fixes, especially for
monitors with a 5:4 aspect ratio (such as 1280×1024) (Shane32)
« Show menu » in Windows builds system menu is now a toggle
to show/hide the menu bar (Shane32)
Fixed broken color palette with CGA composite and EGA
machine emulation. Composite CGA and machine=ega displays
properly again.
According to documentation, IBM PC and PC-98 use different
initial PC speaker frequencies. Update the code to match.
8254 I/O port alias at 3FD9h-3FDFh added, which is needed
for several PC-98 games that program the PC speaker
frequency through those ports instead of through 71h-77h
New Intel 8255 emulation. PC-98 system 8255 emulation
now uses this emulation, along with PC speaker emulation.
Fixed XMS memory copy functions to enable the A20
gate so extended memory copies work correctly whether
or not the DOS application in question made the call
with A20 enabled. This fixes crashes and memory
corruption while installing Windows 3.1 using SETUP.EXE.
« CLS » now sends the proper ANSI escapes to clear the
console in PC-98 mode.
BIOS logo in PC-98 fixed to clear graphics RAM and
set graphics back to 8-color digital mode when booting
to DOS. This should fix palette errors and color issues
with older PC-98/PC-88 games that use the 8-color
graphics modes.
Added PC-98 INT 1Ch timer interval BIOS function,
and timer countdown routine in IRQ 0.
Windows builds now incorporate pdcurses and enable
the debugger interface (bulletshot60)
DOSBox-X now tracks the systemwide keyboard layout
on Windows, and acts on user changes to the keyboard
and language in the system.
Removed hack code in SDL 1.x that sets DOSBox-X’s
keyboard layout to the US layout even if the host
uses anything else.
Fix CPU cycles count increment not to nag you to use
core=dynamic if a) dynamic core is not available or
b) you’re already using dynamic core.
Added dynamic core back, it seems to be very stable
again.
