DOSBox-X v0.83.13 (2021/04/30) 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:
DOSBox-X can now resolve file paths in its config
options that include environment variables on non-
Windows platforms (e.g. ${HOME}..) as well. A new
config option "resolve config path" (in [dosbox]
section) is added to control path resolving in the
config file (e.g. to resolve tildes only by setting
to "tilde", or disable all path resolving). (Wengier)
System menu text in Windows builds now match the text
in the drop-down menus to be translatable by language
files and is compatible with Unicode. (Wengier)
The error "Access Denied" is returned instead of
"File not found" for files opened exclusively in
another program on mounted local drives. (Wengier)
S386C928 hardware cursor fixed to divide X coordinate
by bytes per pixel indicated in the control register
to match apparent Windows 3.1/95 behavior. Cursor
now tracks host properly even in highcolor/truecolor
modes.
Added support for the RetroWave OPL3 hardware player.
Set "oplemu=retrowave_opl3" in [sblaster] section of
the config file to use it. Config options including
"retrowave_bus", "retrowave_spi_cs", "retrowave_port"
are added to adjust its settings. (ClassicOldSong)
Added support for S386C928 hardware cursor color
selection in 256-color mode, which is different
from later cards.
S3 XGA "BYTE SWP" fixed only to byte swap if the
transfer is 16-bit wide. This fixes the dither
pattern drawn by Windows 95/98 when you select
"Shutdown" from the Start menu.
IMGMAKE command is now disabled in the secure mode,
similar to commands like IMGMOUNT. (Wengier)
Added config options "working directory option" and
"working directory default" in [dosbox] section of
the config file to provide various options for the
users to control DOSBox-X's working directory. For
example, DOSBox-X can use the primary config file
directory or the DOSBox-X program directory as its
working directory. You can view the DOSBox-X'safe
working directory with CONFIG -L command. DOSBox-X
is also able to save the working directory that a
user selects to global config files. (Wengier)
DOSBox-X will now also try to read the config file
named dosbox-x.conf in the user config directory
when searching for config files at start.
Added new command-line options -promptfolder and
-nopromptfolder which will cause the folder prompt
dialogs to show or not to show at startup.
Mac OS X builds will prompt the user to select a
folder at startup if run from the Finder (or from
the root directory). The folder selected will then
become the current working directory of DOSBox-X.
This makes it possible to start DOSBox-X with a
config file of your choice and to control where
the capture, save states and other files go.
Fixed Tseng ET4000 640x480 256-color SVGA mode
when using the ET4000.BIN VGA BIOS, or Windows 98.
Added segment limit checks in Normal core for
MOVSB/MOVSW/MOVSD and STOSB/STOSW/STOSD, which is
needed for DOSBox-X to work with the Windows 3.1
S3 86C928 display drivers that use segment limit
exceptions to fake a linear framebuffer.
Added S3 XGA "byte swap" emulation, needed for
correct menu/titlebar display in Windows 3.1 when
using the S3 86C928 driver.
Added YUV (YUY2) overlay to S3 Trio64V+ card
emulation. Tested with XingMPEG under Windows 3.1
and ActiveMovie under Windows 98.
Added machine types for 5 different variations of
S3 chipset: Vision864, Vision868, Trio32, Trio64,
and (experimental) Trio64V+, ViRGE, ViRGE/VX, and
S3 86C928.
Removed second PCI BAR for S3 MMIO register space.
S3 datasheets do not show a second BAR. Windows 95
is perfectly happy without it.
S3 SVGA XGA emulation BlitRect now supports
COLOR_CMP. DirectX-based Windows 95 games are now
able to blit in 256-color mode with a transparent
color key value.
ANSI.SYS emulaion now supports the "Device Status
Report" escape when asked through code 6 (report
cursor position)
Fixed RAM mapping bugs related to MDA/CGA/Hercules
emulation and the "allow more than 640kb" option,
that failed to map RAM as expected, and because of
that, easily triggered a "corrupt MCB chain" error
message.
Worked around the mounting issue for disk or CD
image files with LaunchBox, by allowing a mounting
command-line with single quotes like IMGMOUNT D
'X:\FILES\DOS.IMG' on Windows systems. (Wengier)
Restored Pentium MMX emulation code for the dynamic
x86 core to that of version 0.83.11 for better
compatibility with some Windows 9x games. (Wengier)
Added "compresssaveparts" config option (in the
[dosbox] section) which when set to false will not
compress the components in saved states. (Wengier)
When the current reported DOS version is less than
7.x and the user tries to mount a LBA or FAT32 disk
image, DOSBox-X will now show a message to ask if
the user wants it to set the required DOS version
automatically and proceed. (Wengier)
DOSBox-X will now show the folder mounted after
mounting to a drive from the menu. (Wengier)
Fixed MOUNT and IMGMOUNT commands unable to mount
directories or image files that contain non-ASCII
characters in the code page on Windows. (Wengier)
Fixed CapsLock may not work properly in Windows
SDL1 builds when -fs option is used. (Wengier)
Fixed the cycle information on the title bar when
the Turbo mode is enabled. (Wengier)
Fixed that some games using the DOS4GW Extender
may not work due to swap file issue. (Wengier)
Fixed that the clipboard copy and paste may not
work when the current code page is 808 or 872
and you are using Windows. (Wengier)
Fixed the handling of the "Save & Restart" button
in Configuration Tool when using Direct3D output
in Windows SDL2 builds. (Wengier)
Fixed incorrect display issue when using TrueType
font (TTF) output with customized screen dimension
when fastbioslogo=true is set. (Wengier)
Fixed CD audio not looping for individual tracks
in games like Alien Trilogy. (kcgen)
The command "MIXER /LISTMIDI" now lists the ROM
directory/files and sound fonts for MT32, Synth
and FluidSynth MIDI device when active. (Wengier)
Debugger "DOS XMS" command will only list handles
that are allocated, or with nonzero address or
nonzero size, to avoid showing irrelevant
information. (joncampbell123)
Added LOADFIX -EMS option to allocate/free
EMS (expanded memory). (joncampbell123)
LOADFIX -D -XMS will free all XMS blocks
allocated by LOADFIX -XMS. (joncampbell123)
LOADFIX -A will not allocate memory unless there
is memory below 64KB to fill. (joncampbell123)
INT 15h PS/2 mouse functions now clear pending
PS/2 mouse interrupt as part of the BIOS call.
This should resolve unresponsive mouse issues
with Windows 3.1. (joncampbell123)
Add config option "mt32.model" in the [midi]
section to force a MT-32 model to use. (Wengier)
Updated the MUNT MT-32 library to the latest
version 2.5.0. (Wengier)
Updated FLAC decoder library to the latest version
(0.12.29 by David Reid). (Wengier)
Integrated SVN commits (Allofich)
r4436, r4437: Rewrite store integer instructions
to check if the result fits.(vogons 78127)
r4447: Attribute Controller port alias on EGA
machine. Fixes EGA display of older Super Pac-Man
release.
