DOSBox-X v0.83.22 (2022/01/31) 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:
Added Pentium 3 Processor Serial Number emulation.
Serial number can be set from dosbox-x.conf or not
set, in which case it will act as if disabled by the
BIOS. (joncampbell123).
Added Pentium III cputype, added SSE register set,
added SSE instructions to debugger disassembler,
added some initial SSE instructions. (joncampbell123)
Added some MSRs expected by Linux, Windows, and
tools like CPU-Z to make them happy. (joncampbell123)
Added FXSAVE/FXRSTOR which makes Linux happy with
Pentium III emulation. (joncampbell123)
Allow WRMSR to set time stamp counter, as it is known
though undocumented a standard since the Pentium
(joncampbell123).
Added debugger command to show global and per-voice
status of the Gravis Ultrasound emulation. May come
in handy for programmers who wish to write their own
GUS routines, and for Trixter who brought up the
subject of determining whether a program plays music
with the GUS or treats it like a dumb sound card.
(joncampbell123).
Added debugger command to show SSE register file, and
to set SSE register contents. (joncampbell123)
Added debugger command to show MMX register file, and
to set MMX register contents. (joncampbell123)
Added support for expressions within parenthesis in
debugger expression handling. (joncampbell123)
Added & (AND), ^ (XOR), and | (OR) operators, and
<< and >> bit shift operators to debugger expression
handling. (joncampbell123)
Added multiply (*) and divide (/) operators to debugger
expression handling. Order of operations applies, so
given mixed addition and multiplication, the multiply
is done first then the result is added. Also added
support for the modulo (%) operator to the debugger
expression handling. (joncampbell123)
Revised debugger expression handling to correctly
parse arithmetic operators with order of operations
in mind. Prior to this fix, consecutive subtraction
would cause seemingly illogical results, for example
"10-1-1-1" would yield "9" instead of "7" because
subtraction was handled in the wrong order. This fix
also makes mixed addition and subtraction possible.
NOTICE: Remember that all numbers going in and
coming out of the expression handler are hexadecimal,
NOT decimal! (joncampbell123)
Fixed simple expression handling in the debugger.
Revised hexadecimal vs register parsing so that
hexadecimal numbers that happen to start with
the name of certain CPU flag registers does not
cause confusing results. Prior to this fix,
hexadecimal numbers like "dfe" or "af0" were
impossible to enter without leading zeros or
quotes because the parser would confuse the
first digits with the DF and AF bits of the FLAGS
register. (joncampbell123)
Added menu options "AMD Athlon 600MHz" and "Pentium
III 866MHz EB" within the group "Emulate CPU speed"
(under "CPU") for CPU speeds to emulate. (Wengier)
Added support for archive, hidden, system attributes
on mounted local and overlay drives for non-Windows
platforms by using special file(s). (Wengier)
Added config option "special operation file prefix"
(in [dos] section) to speciay an alterantive file
prefix for DOSBox-X's special operations on mounted
local and overlay drives. (Wengier)
Added code page 3021 for the MIK character set used
by the Bulgarian language (as in FreeDOS). (Wengier)
Added language file for the Brazilian Portuguese,
available from Windows installer. (altiereslima)
For piping (|), DOSBox-X will now also try C: drive
as a temporary piping path if current directory is
read-only and the environment variable %TEMP% (or
%TMP%) is not set. (Wengier)
For clipboard copy, CR+LF will now be used instead
of LF on Windows for better compatibility. (Wengier)
Disk images are automatically mounted as read-only
(instead of failing) now if the image files are
read-only and the users do not explicitly specify
read-only mode for the disk images. (Wengier)
The default value of config option "autofixwarning"
(in [dos] section) is now "false", and it is now
changeable via CONFIG command. (Wengier)
The default output for Linux SDL1 builds is changed
from opengl to surface, unlike Linux SDL2 builds
whose default output remains opengl. (Wengier)
Native Windows menus is supported in Windows SDL2
builds just like Windows SDL1 builds. It is possible
to force SDL-drawn menus for both Windows SDL1 and
SDL2 builds at compile time. (Wengier)
Setting "windowposition" to "-" in the configuration
will leave DOSBox-X window position as is instead of
a specific position or being centered. (Wengier)
For printing, the SarasaGothicFixed TTF font will
also be searched for DBCS code pages. (Wengier)
Added config option "showdbcsnodosv" (in the [dosv]
section) which when set to true enables rendering of
Chinese/Japanese/Korean characters for DBCS code
pages in non-DOS/V, non-PC98, and non-TTF mode.
Video capturing started from TTF output will enable
DBCS characters when possible. (Wengier)
Changing DBCS code pages is supported for standard
modes (i.e. non-DOS/V, non-PC98 and non-TTF modes)
using CHCP command. (Wengier)
Fixed issues with certain DBCS characters for the
DOS/V system. (Wengier)
Fixed slow blinking text in TTF output. (Wengier)
Fixed copying box drawing characters to clipboard
not working in non-TTF JEGA mode. (Wengier)
Fixed background for the Configuration Tool when
the TTF output is active. (Wengier)
Fixed DBCS characters not showing up when capturing
screenshots in TTF CJK mode, or they do not show up
properly in the Configuration Tool when "autodbcs"
is set to "false" in the configuration. (Wengier)
Fixed media keys presses by ignoring these keys in
Windows SDL1 builds. (maron2000)
Fixed IOCTL & ASPI interfaces for mounting physical
CD drives on the Windows platform. (Wengier)
Fixed the issue of loading scalers in the previous
version. A message box will only show up if you
append "prompt" to the scaler option. (Wengier)
