EmuCR: DOSBoxDOSBox-X v0.83.12 (2021/04/01) is released. DOSBox-x is a branch of DOSBox. 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:
Tandy graphics emulation fixed to accept 8 bits
for vertical total and vertical display CRTC
registers, which is needed for the tweaked
graphics mode used by Math Rabbit to display
correctly.
INT 10h will no longer fill in three fields in
the BIOS data area (video CTL, char height, and
video switches) unless the machine type is
EGA or VGA. Those fields do not exist otherwise.
Certain games like Mindscape's "Road Runner" game
require those fields to be zero as part of it's
Tandy detection routine.
PCjr mode will omit the reserved graphics RAM
MCB block, and will subtract 16KB from the top
at the BIOS level, if emulating 128KB system
memory or less.
You can now run PCjr mode with as little as
128KB of RAM. Removed 256KB minimum check from
DOS kernel. Certain games (Mickey's Space
Adventure) require memsizekb=128 and memsize=0
in PCjr mode or else it will not work correctly
due to how the game locates video system memory.
Fixed Tandy mode to place video memory at the
top of conventional memory and allow running
Tandy mode with a memsizekb setting as low as
64KB, though 256KB or higher is recommended.
Added Tandy "real memory size" field in the
BIOS data area.
Tandy emulation updated to subtract 16KB from
top of conventional memory, which fixes some
games and follows DOSBox SVN behavior and real
hardware according to others on the Vogons forums.
Fixed bug that limited Tandy mode to 624KB of
conventional memory. 32KB of video RAM is taken
from top of memory, losing half of the 32KB
breaks games that write to the system RAM instead
of B800:0000 segment and causes half the graphics
to not render.
CD-ROM image emulation now supports ISO images
that are 2GB or larger, 32-bit integer size limit
has been lifted.
Increased upper limit of "prebuffer" config option
(in [mixer] section) from 100 to 250. It is still
recommended to set a value less than 100. (Wengier)
Added scrollbar buttons to the Configuration Tool,
so that the scrollbars better resemble the style of
the Windows 3.1 scrollbars.
The help window for the Configuration Tool will now
display possible and default values for the config
options in addition to the descriptions. (Wengier)
Updated the MMX patch code by kekko. (Wengier)
MIXER command now supports the /GUI option to show
a popup window to display the mixer information.
Also improved its /LISTMIDI option which will show
the name of the current MIDI handler and you can
optionally specify a MIDI handler name (win32/alsa)
to show the information for this handler. (Wengier)
Improved the compatibility of AUTOTYPE command with
games like Asterix & Obelix. (Wengier)
The config options ttf.wpbg, ttf.bold, ttf.italic,
ttf.underline, ttf.strikeout, and ttf.char512 can
now be modified dynamically with CONFIG -SET ...
commands, e.g. CONFIG -SET ttf.wpbg=2. (Wengier)
The minimal value for the ttf.ptsize config option
has been decreased from 10 to 9. (Wengier)
Added menu item "Save logging as..." (under "Help"
-> "Debugging options") to save the current logging
content to the specified file. (Wengier)
Added slirp backend support for the NE2000 network
feature (in addition to the existing pcap backend).
There are config sections named [ethernet, slirp]
and [ethernet, pcap] now to set the options for the
slirp and pcap backends respectively. Please refer
to the networking guide in the DOSBox-X Wiki for
more information about the backends. (Jookia)
FAT driver can now support PC-98 HDI images with
partitions that start at any physical sector even
if the start is not a multiple of the ratio of
logical to physical sector size. This allows the
HDI image of Dragon Knight 4 to mount.
Control character 7 (BEEP) is now allowed while
executing batch files without warnings. (Wengier)
With the setting "core=auto" DOSBox-X now updates
the menu in the "CPU core" menu group automatically
between "Normal core" and "Dynamic core" to reflect
the CPU core which is currently in use. (Wengier)
Fixed Windows 95/98 installation failures caused by
FAT driver and DOS API changes in previous version.
Fixed well-intended but erroneous fall through case
in the INT15 handler that prevented 3rd party mouse
drivers from detecting the PS/2 mouse.
Fixed the color issue with the Configuration Tool
in the macOS SDL1 build. (ant_222)
Fixed switching ttf.cols, ttf.lins, and ttf.font
options dynamically in full-screen mode. (Wengier)
Fixed menu options "Increase TTF font size" and
"Decrease TTF font size" (both under "Video" =>
"TTF options") not working (but keyboard shortcuts
and those in the system menu work). (Wengier)
Fixed setting option "ttf.wp=xy3" or "ttf.wp=xy4"
not working (but "ttf.wp=xy" did work). (Wengier)
Fixed preview function in WordStar not working for
TrueType font output in previous version. (Wengier)
Fixed the issue that caused Windows 3.x group file
corruption on hard disk image files. (SnikoLoft)

recording, and to start keymapper, from config.
