DOSBox-X v0.82.6 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:
Resizing the window in SDL 1.x Windows builds
fixed to work correctly in the latest build
(1803) of Windows 10. Prior to this fix, resizing
the window on that build would quickly hit a deadlock
that prevented the user from moving or resizing the
window again after that point.
PC-98 dosbox.conf option added to select between
accurate key/shift mapping, vs an alternate mapping
appropriate for US keyboards (Yksoft1)
SDL 1.x for Linux/X11 modified to differentiate
Ro and Yen keys despite X11 xkbmap apparently
mapping both to the backslash. The keymap is
queried to detect the scancodes at startup
in order to return the correct SDLK constant.
SDL 1.x and DOSBox-X mapper code updated to
correctly map Ro, Yen, @ ^ ; : keys on a JP
keyboard in Windows and Linux.
PC-98 keyboard BIOS handling updated to generate
ASCII codes according to PC-98 layout, instead
of by US keyboard layout.
Mapper updated to support @ (at sign) key,
^ (caret) key, and a few other keys that
exist on JP keyboards.
"Hold" modifier for mapper bindings fixed.
It is now possible to tap the key again to
release the hold.
VHD differencing disk support added (Shane32)
INT 18h AH=0Ah updated to support 20-line
text mode. Some games use the 20-line text
mode to space the text out vertically.
Such games will display correctly now.
INT 18h now maintains text layer state
in BIOS data area byte 0x53C, just as
the actual BIOS does.
Added PC-98 INT 18h function AH=0Ah and
AH=0Bh to support BIOS calls that enable
"Simple Graphics" mode. This fixes
problems with other games having vertical
lines over the graphics, even though
these games do not appear to use the
simple graphics at all. (yksoft1)
Added support for PC-98 "Simple Graphics"
mode of text layer attribute bit 4. When
enabled, the attribute bit 4 changes
meaning from vertical line to a bit
indicating that the 8-bit character is
a low resolution 2x4 bitmap to be
displayed in the text layer. This fixes
score and status display in Carat.
PC-98 INT 18h now implements AH=31h to
report CRTC, text and graphics state and
24khz/31khz video mode selection. This
fix allows some games including Touhou
Project to pace it's gameplay correctly
in either video mode.
MinGW HX DOS builds default to host key
F12 again
PC-98 mode now offers selection between
24khz and 31khz video modes (yksoft1)
KEYB.COM fixed to load only the fonts the
ROM BIOS has allocated. This fixes a guest
system crash if using KEYB.COM with
machine=ega
Moved host key to F11 for Windows. F12 is
already taken by some internal debugging
voodoo within Windows itself.
DOSBox-X codebase now strongly encourages
compilation with C++11, will become
required soon.
BOOT command fixed to make it possible to
IMGMOUNT multiple floppies to drive 1, and
boot from another disk in drive 0. This
should enable the use of DOSBox-X with
PC-98 games that expect to boot from drive
A and the user to rotate through floppies
in drive B.
IMGMOUNT fixed to support mounting with no
filesystems and multiple disk images, and
using the "swap floppy" command to rotate
through them.
Added options to BOOT command that allows
specifying multiple disk images and an option
that says to swap disk images only through
one drive.
VHD dynamic support added (shane32)
INT 10 AH=9 background color fixed in 256-color
VGA modes.
Intro text updated to reflect new default
key bindings.
Mapper shortcuts not in common use now exist
without any default binding, and most existing
default bindings are now associated with the
"host" key.
Added 4th modifier "host" key to the mapper.
This "host" key is F12 by default. The intent
is to eventually move most mapper shortcuts
to some combination of F12 and another key,
rather than many shortcuts scattered over the
keyboard. Existing dosbox mapper files should
continue to work.
Renderer and 32bpp VGA display code fixed to
reorder RGBA order for correct display on Intel
Mac OS X systems. Mac OS X, on Intel systems,
uses a strange BGRA 32bpp format that requires
some adjustment on our part to display correctly.
Added more 24bpp INT 10h VESA BIOS modes.
Removed per-sector debug messages from VFD/FDD
image support code.
