0.83.7
- The primary DOSBox-X Wiki is now located at the
URL: https://dosbox-x.com/wiki (Wengier)
- Implemented the x86 dynamic core for both 32-bit
and 64-bit systems by re-porting the code from SVN.
Dynamic core now supports either the dynamic_x86
or the dynamic_rec core. The dynamic_x86 core will
be used by default for x86 and x86_64 platforms and
if "core=dynamic" is set, and Windows 9x can be run
in this dynamic core (although at this time may
encounter some issue with the S3 driver). You can
also explicit specify setting "core=dynamic_x86" or
"core=dynamic_rec" for either the dynamic_x86 core
or the dynamic_rec core. Also thank joncampbell123
for the 64-bit fix. (Wengier)
- You can now use your own save file (in addition to
save slots! There are now a "Use save file" toggle
item and "Browse save file..." for browsing save
files on your computer. A config option "savefile"
(in [dosbox] section) is added to specify a save
file to use at start. (Wengier)
- Save state feature now allows users to optionally
enter remarks when saving a state. A submenu group
"Save/load option" is added (under "Capture") where
you can toggle menu items "No remark when saving
state" (for disabling input of remarks when saving)
and "force load state mode". A menu item "Display
state information" is added as well to display the
information of the saved state. (Wengier)
- DOSBox-X will now use native dialog box to display
quit warnings and save state errors. (Wengier)
- Changed some DOS error messages (such as "Illegal
command" which now reads "Bad command or filename")
similar to real DOS systems. (Wengier)
- ADDKEY and INT2FDBG commands now appear as programs
on Z: drive instead of shell commands. (Wengier)
- Improved the -z (move virtual drive Z:) function of
MOUNT command. You can move the virtual drive as
many times as you want, and save/load states will
work even after you move the Z: drive. (Wengier)
- Enhanced the config option "freesizecap" to allow
the setting "fixed" which is the same as "false",
and a new setting "relative" is added, which will
be similar to the setting "fixed" but the reported
free disk size will also change relative to the
change of the free disk size ever since. (Wengier)
- Added support for Opus CD-DA tracks by porting and
cleaning up the source code from other projects.
Many thanks to Marty Shepard and kcgen. (Wengier)
- Support for FluidSynth MIDI Synthesizer is now
included in the MinGW builds by default just like
Visual Studio builds. Set "mididevice=fluidsynth"
and a soundfont file to use it. (Wengier)
- Enabled xBRZ scaler for Visual Studio SDL2 builds
just like Visual Studio SDL1 builds. (Wengier)
- Added menu item "Show Sound Blaster configuration"
under "Sound" menu to show the current information
about Sound Blaster, and also menu item "Show MIDI
device configuration" (also under "Sound" menu)
to show information about the current MIDI device
such as the soundfont file in use. (Wengier)
- Added "Mount multiple disk/CD images" option to the
mounting options of the Drive menu to allow users
to mount more than one disk/CD images to a drive,
swappable from the menu. Also added separators to
the Drive submenu to make it look better. (Wengier)
- Added new CPU types to the "Emulate CPU speed" menu
group namely 286-25MHz, 386DX-25MHz, 486DX4-100MHz,
486DX5-133MHz, Pentium-60MHz, Pentium-75MHz, and
Pentium-90MHz. Thanks again for the data provided
by the user maximus105. (Wengier)
- You can now select a special key (e.g. Alt+Tab,
Ctrl+Break, Ctrl+Alt+Del, etc) to be sent from the
key defined in the mapper editor. The key can be
selected (Ctrl+Alt+Del by default) from the "Send
special key" menu group in "Main" menu. (Wengier)
- Added full Ctrl+Break emulation at the BIOS and
DOS level, updated console emulation to match.
The "Pause" mapper shortcut is now moved to
HOST[F11/F12]+Pause instead of Ctrl+Pause so that
Ctrl+Break can work properly for users, and the
function to send the Ctrl+Break key from the menu
("Send special key" under "Main") is added. Also,
the PC-98 STOP key now functions the same as the
Ctrl+C and Ctrl+Break keys in IBM PC mode.
- Added functions "CopyToClipboard" and "QuickRun" to
the mapper editor so that you can use shortcuts to
activate them (default shortcuts: HOST(F11/F12)+A
and HOST(F11/F12)+Q respectively), and a default
shortcut HOST(F11/F12)+V is added to the clipboard
paste function. Meanwhile, FullCore and SimpleCore
shortcuts are removed from the mapper. (Wengier)
- Added two new menu items in the "Shared clipboard
functions" menu group under "Main", including "Copy
all text on the DOS screen" which will copy all
screen text to the clipboard, and "Stop clipboard
pasting" which allows user to stop pasting in the
middle of pasting long clipboard content. (Wengier)
- The mouse copy/paste feature is now available for
non-Windows systems on SDL2 builds. Also, pasting
from the clipboard with a mapped shortcut is also
available for Linux/X11 on SDL1 builds. (Wengier)
- Added "Use US keyboard layout" toggle menu item in
the "PC-98" menu group under "Video" to select
whether to force the default US keyboard layout in
PC-98 mode, same as the "pc-98 force ibm keyboard
layout" config option in [pc98] section. Also moved
the "PC-98 PIT master clock" options from the "DOS"
menu to this menu group. (Wengier)
- The full dosbox-x.reference.conf file is renamed to
dosbox-x.reference.full.conf. The original file
dosbox-x.reference.conf now contains common config
options instead of all config options. (Wengier)
- The CONFIG command and Configuration Tool will now
save common and modified config options by default.
The -all command-line option (or "Save all options
to the configuration file" checkbox) will force to
save all config options. A new -mod command-line
option is added to CONFIG command to save modified
config options only, and a new -norem command-line
option is added to not write remarks. (Wengier)
- Updated the Windows installer to default to the
"typical" installation. For the full installation
start menu items will be added for DOSBox-X builds
copied to subdirectories. A new checkbox "Write
common config options (instead of all) to the
configuration file" is added which when checked
will only write common and modified advanced config
options to the config file. Furthermore, for both
"typical" and "full" installations the Windows
installer will now also copies the DLL files
inpout32.dll (32-bit) and inpoutx64.dll (64-bit) to
the DOSBox-X install directory for use with the
direct parallel port passthrough feature. (Wengier)
- Improved Flatpak support for Linux. (rderooy)
- Improved message for the -help command-line option,
adding for example -silent and -socket command-line
options in the help messages. (Wengier)
- Added -silent command-line option to run DOSBox-X
silently (without showing the DOSBox-X window) and
then exit after executing AUTOEXEC.BAT. (Wengier)
- Fixed command-line option -socket not working for
the null-modem feature. (Wengier)
- Fixed issue that aspect ratio not being respected
in full-screen mode when a GLSL shader is enabled
with an OpenGL output. (Wengier)
- Fixed toggle in the "Frameskip" menu group did not
change when selecting a different option. (Wengier)
- Fixed shelling from programs may not work when the
shell config option is set. (Wengier)
- The default country setting ("country" option in
[config] section]) now defaults to auto-detection
if possible, or 81 (Japan) in PC-98 mode. (Wengier)
- Increased the default maximum DOS files (adjustable
from [config] section) from 127 to 200. (Wengier)
- Improved resetting with LOADLIN program. (Wengier)
- Improved Gravis Ultrasound (GUS) implementation to
make it more accurately represent the GUS DMA state
as expected by the running DOS software.
- The archive attribute will no longer automatically
be applied to directories on non-Windows systems.
This fixed issue with PLAYMIDI.EXE from Gravis
Ultrasound when listing directories. (Wengier)
- Applied hack to allow the low DMA channel detection
in the SB16 DIAGNOSE program to work. (Wengier)
- The default setting of the clip_paste_speed option
has been changed from 20 to 30, which will help
prevent lost keystrokes when pasting from the host
clipboard for some programs. (Wengier)
- With Pentium CPU setting (cputype=pentium) DOSBox-X
no longer reports FDIV bug by default. An advanced
config option "report fdiv bug" is added to report
such CPU bug when set to true. (rderooy & Wengier)
- Added support for the XDG_DATA_HOME environment
variable for config directory in Linux. (rderooy)
- Added support for compiling with pcap for Windows
MinGW builds. (Jookia)
- Added config option "windowposition" (in [sdl]
section) to set the window position at startup in
the positionX,positionY format. (tomba4)
- Added config option "raw_mouse_input" (in [sdl]
section; SDL2 builds only) to bypass the operating
system's mouse acceleration & sensitivity settings.
Implemented by NicknineTheEagle.
- Added config option "startquiet" (in [dos] section)
which when set to true will silence the information
messages before launching Windows programs to run
on the Windows host. A toggle menu item "Quiet mode
(no start messages)" is added to the "Windows host
applications" menu group in "DOS" menu. (Wengier)
- The menu "Show details" (under "Main") is renamed
to "Show FPS and RT speed in title bar". (Wengier)
- Add menu group "Text-mode" under "Video" menu to
change some text-mode related video settings, such
as changing the number of rows and columns. A zip
package named TEXTUTIL.ZIP is added to the Z drive
that contains various utilities (such as CGA.COM,
EGA.COM, 132X25.COM, 132X43.COM) to change current
video setting from the command line. Also added a
config option "high intensity blinking" which when
set will display high intensity background colors
instad of blinking foreground text. The menu item
"Allow 9-pixel wide fonts" is moved from the menu
group "Compatibility" to here. (Wengier)
- Added "Debugging" menu group under "Help" menu, and
moved items from the "Video" Debug and "DOS" Debug
menus and the debugger here (debug builds only).
Also allowed to hide/show the console or debugger
window in Windows debug builds. With the menu item
"Console wait on error" checked the Windows console
window will wait for the ENTER key before closing
itself after an E_EXIT occurs. (Wengier)
- Updated MPXPLAY to latest version 1.65. (Wengier)
- Integrated SVN commits (Allofich)
- r4386: Correct MPU-401 clock-to-host function to
operate independently of playing. Fixes hang at
exit when playing Roland music in demos by The
Phoney Coders. Clamp tempo to valid range.
- r4384: ICW1 on the PIC clears the Interrupt Mask
Register. Fixes Antagony and quite a few demos that
expect IRQs to be unmasked.
- r4382: Refine adlib timers a bit more and make
reading the Adlib take a bit more time.
- r4378: Prevent some possible deadlocks with sti
in dynrec core.
- r4375: Improve compatibility with older Intel
chipsets
- r4374: Add a bit of hack so cycles=max/auto 90%

the file close function.
- r4368: Improve error codes for some DOS file functions.
- r4367: Change FPU_FBST to only write 18 decimals
instead of the wrongly 19, this makes it possible
to switch 64 integers which in turn fixes some
rounding issues. (jmarsh)
- r4282,r4283: Switch to a different way to calculate
DBOPL table offsets.
- r4280: Prevent GenerateDMASound from running with
input of 0.

- r4264: Pick some lowhanging fruit. (some memory
leaks and unused variables)
- r4262: missed one
- r4261: These actually use float as input.
- r4258: Rename bios tester to biostest and make it
debug only to avoid people trying to load real
bioses.

into a bios image for running cpu tester bios.
0.83.6
- Improved internal Voodoo card hardware emulation,
such as fixing the font issue with the 3dfx version
of Tomb Raider when using non-Glide mode. Portions
of the code are ported from DOSBox ECE. (Wengier)
- Added OpenGL shader support by porting the feature
from DOSBox SVN. GLSL shaders are now supported in
both SDL1 and SDL2 builds, and this also allows
pixel-perfect scaling to be enabled for the OpenGL
outputs. The config option "glshader" (in [render]
section) can be used to specify a GLSL shader file
or a built-in shader when the output is set to
"opengl" or "openglnb". For example, you can use
the setting "glshader=sharp" (built-in shader) or
"glshader=pixel_perfect" (with GLSL shader file)
for the pixel-perfect scaling mode. The Windows
installer will also copy several GLSL shader files
to the "glshaders" subdirectory of the DOSBox-X
install directory to be used directly. (Wengier)
- Support for FluidSynth MIDI Synthesizer is now
included in the Windows Visual Studio builds by
default. Set "mididevice=fluidsynth" and a sound
font (e.g. GeneralUser_GS.sf2) to use it. (Wengier)
- Updated the MUNT MT32 emulation library to its
latest version 2.4.0. A few new MT32 config options
(starting with "mt32.") are added to [midi] section
of the DOSBox-X configuration. (Wengier)
- The DOSMID and MPXPLAY programs have been built
into DOSBox-X, both can be found on the Z drive and
feature full-screen user interfaces with support
for command-line usages (use /? option for help).
DOSMID can play MIDI/RMI/MUS audio files, whereas
MPXPLAY is a powerful and flexible audio player
with support for a variety of formats including
AAC/AC3/APE/FLAC/MP2/MP3/MPC/OGG/WAV and more with
playlist support. (Wengier)
- The mounting options "Mount as Hard Disk", "Mount
as CD-ROM", "Mount as Floppy", "Mount disk image"
and "Boot from disk image" (previously only for
Windows) in the "Drive" menu and the "Quick launch
program..." in the "DOS" menu are now available
for non-Windows platforms as well. (Wengier)
- Added "Shared Windows clipboard functions" menu
group under "Main", which allows you to enable
or disable the different ways for DOSBox-X to
communicate with the Windows clipboard. (Wengier)
- Added config option "dos clipboard api" in [dos]
section to control whether to enable the DOS APIs
for communications with the Windows clipboard for
DOS applications. (Wengier)
- Added config option "clip_mouse_button" to select
a mouse button (middle, right, or none; with right
mouse button being the default) for copying to and
pasting from the Windows clipboard. (Wengier)
- The mouse wheel movements will be automatically
converted into up/down arrows by default for the
intergrated DOS now. You can also enable it for
the guest system from the "Main" menu ("mouse wheel
movements" -> "Enable for guest systems also") or
from the config file. (Wengier)
- Added "Emulate CPU speed" menu group (under "CPU")
to emulate the speed of a specific CPU class. The
cycles to emulate are approximations of the actual
CPU hardware, and they are available thanks to data
provided by the user maximum105. Also added config
option "cycle emulation percentage adjust" in [cpu]
section for users who would like to make relative
percentage adjustments (between -25% and 25%) in
case it is necessary. (Wengier)
- Added SORT command from FreeDOS. It can be used to
sort input, e.g. "TYPE FILE.TXT | SORT". (Wengier)
- Added DELTREE command to delete a directory and all
the subdirectories and files in it as in a real DOS
system. Please use it with caution. (Wengier)
- The command for starting the Configuration Tool has
been renamed from "SHOWGUI" to "CFGTOOL". A new
command-line option -gui is added to CONFIG command
to start the Configuration Tool as well. (Wengier)
- DOSBox-X now includes ZIP.EXE and UNZIP.EXE from
InfoZip for zipping and unzipping files in DOS.
Both programs will appear on the Z drive. (Wengier)
- The powerful DOS CD player called SJGPLAY has been
built into DOSBox-X. You can now find the program
CDPLAY.EXE in the Z drive for playing Audio CDs in
DOS, which supports both graphical and command-line
usage, and you will also find a text file named
CDPLAY.TXT in the Z drive for a quick usage guide.
A zip package including full documentation and some
extras will additionally appear as SJGPLAY.ZIP in
the Z drive. This freeware program was written by
Steve Gray and is now included in DOSBox-X with
explicit permission of the author. (Wengier)
- DOSBox-X will now by default show a quit warning
if a DOS program or game, or a guest system is
running. The previous behavior can be set with
"quit warning=autofile". (Wengier)
- The welcome banner when DOSBox-X starts has been
improved for a better looking and should provide
more helpful instructions for users. (Wengier)
- Add new "Help" menu which includes menu items
"Introduction", "DOSBox-X homepage", "DOSBox-X Wiki
guide", "DOSBox-X support" and "About". (Wengier)
- Improved the message when automatically re-running
the executable which failed with the "Packed file
is corrupt" error. Also added the "autoloadfix"
config option which when set to "false" will not
automatically re-run such programs. (Wengier)
- The display for several section names in DOSBox-X's
graphical configuration tool has been capitalized
or modified otherwise to look better. A default
shortcut key HOST(F11/F12)+C is added for starting
the graphical configuration tool. (Wengier)
- Added the "Show advanced options" checkbox in the
main screen of the Configuration GUI to toggle
whether to display all config options for the
sections. If unchecked (default), it will show
common config options instead of all of them. A
new config option "show advanced options" is added
which when set to "true" will make the checkbox
checked by default. (Wengier)
- Added code to cap the scan line length given to
the VESA BIOS given the video mode. This prevents
VBETEST.EXE from doing test patterns smaller than
the actual display, which can happen with 32bpp
320x200 modes and 1MB or less video RAM.
- VESA BIOS Set Scan Line Length fixed to properly
report and handle scan line length for 16-color
SVGA planar modes. VBETEST 16-color modes now
display correctly.
- Added option to control whether VESA BIOS panning
(the original VBE call) waits for vsync.
- Moved video related config options from [dosbox]
section to its own [video] section. These options
in existing config files will be automatically
redirected to the [video] section from the [dosbox]
section when DOSBox-X starts. Windows installer can
also move such config options from existing config
files automatically. (Wengier)
- Cleared modem phone book before parsing it. Thank
NicknineTheEagle for the improvement.
- Improved the help message of MOUNT command. Also
added option -examples to show its usage examples,
similar to IMGMOUNT and IMGMAKE commands. (Wengier)
- Fixed freeze when trying to reboot the internal
DOS when using a different code page and it is in
CGA or EGA emulation modes. (Wengier)
- DOSBox-X will now try to use the internal DOS date
and time (instead of always using the host date and
date) for file modication timestamps. (Wengier)
- Added menu item "Expanded memory (EMS)" under "DOS"
menu to dynamically enable or disable EMS memory
at run-time. You can now also modify EMS memory
with CONFIG command from command-line. (Wengier)
- Added config option "drive z hide files" (in [dos]
section) to hide or remove files listed (separated
by spaces) from the Z drive. If a file has a "/"
prefix (e.g. "/INTRO.COM"), then the specified file
will have the hidden attribute ("DIR /A" will list
all such files) instead of completely disappearing
from the Z drive. (Wengier)
- You can now add your own programs or files to the
Z drive! Put your programs or files in the drivez
directory located in the DOSBox-X program folder
or the DOSBox-X configuration directory, and they
will automatically appear on the Z drive. If any of
the files have the same names as the built-in ones,
they will replace the built-in files. For example,
you can replace the built-in EDIT.COM and XCOPY.EXE
programs (from FreeDOS) with MS-DOS counterparts.
Windows installer will now automatically create a
drivez directory with a README.TXT file in it too.
For subdirectories support please use MOUNT command
to mount local directory instead. (Wengier).
0.83.1
- Sound Blaster emulation fixed to better handle Goldplay
mode detection false positive in 1994 demoscene demo
myth_dw.zip when using Sound Blaster Pro setting in
the demo. The initial state before music starts is
like Goldplay mode, but when music actually starts the
DMA programmed to normal state without restarting
DMA playback.
- dosbox-x.conf is now recognized as the default config
file name in addition to dosbox.conf. The sample config
file "dosbox.reference.conf" has been renamed to
"dosbox-x.reference.conf" as well (Wengier)
- Tandy DAC output fixed to slowly ramp last sample to
zero DC sample (128) when switched off. This fixes
loud popping (DC offset) problems with Tandy DAC
sound effects in Prince of Persia. This new behavior
also seems to match real Tandy 1000 hardware according
to video captures of it's audio/video outputs while
playing Prince of Persia on it.
- Tandy/PCjr 3-voice fixed to respond to I/O port 0xC0
regardless of 8-bit or 16-bit I/O (fixes Prince of
Persia).
- Write-protecting a disk image in IMGMOUNT and BOOT
commands now supported by putting a leading colon (:)
before the image file name. Works with disk swapping;
e.g. "BOOT :C:\DISK1.IMG C:\DISK2.IMG" only write-
protects C:\DISK1.IMG but not C:\DISK2.IMG. The new
config option "leading colon write protect image" can
be used to disable or enable this behavior (Wengier)
- Support for changing DOSBox-X internal time (Wengier)
- Support for pipes (|), e.g. "DIR | MORE" should now
work as expected; it is recommended to set the %TEMP%
(or %TMP%) environment variable to a writable directory
inside DOSBox-X before using pipes (Wengier)
- Improved redirections using "<" or ">" (Wengier)
- Improved Ctrl+C handling in some commands (Wengier)
- Improved Tab completion in the command shell (Wengier)
- Improved -get & -set options for the CONFIG command,
e.g. support for config options with spaces (Wengier)
- Improved REN (or RENAME) command to support wildcards
(* and ?) in the source and/or target files (Wengier)
- Some improvements to commands like MORE & VER (Wengier)
- Added BREAK, VERIFY and TRUENAME commands as in a real
DOS system. Type "[command] /?" for help info (Wengier)
- Implemented FOR command to run a specified command for
each file in a set of files. Also added LFNFOR command
to control whether to use long filenames in the FOR
command as in MS-DOS 7+ (Wengier)
- Implemented ATTRIB command to view and set attributes
of files or directories (Wengier)
- Added emulation of R (readonly) attribute bit for
Linux and Unix systems through the user-writable
file mode bits of the filesystem.
- Fixed PC DOS 2000 crash during installation.
- PC speaker: Mode 3 (square wave) and a counter value
of 1 produces a low frequency square wave. Ulrasonic
frequencies do not begin until count == 2. This fixes
helicopter noises in Paratrooper.
- Fixed PC speaker emulation to allow higher PC speaker
frequencies (10x the value of pcrate) to reduce
hiss/noise/aliasing noise that occurs when games
program ultrasonic frequencies into the counter to
"silence" the speaker. "Titus the Fox Marrakech and
Back" should no longer have audible hissing noises
between beeps when the game is using the PC speaker.
- Increased DOS device limit, to avoid E_Exit() crash
if all LPT and COM devices are enabled along with
the new CLIP$ device.
- Minimum MCB free default changed to better reflect
a typical MS-DOS setup with minimal to no drivers.
This should result in a report of 600K-ish memory
free, which is equivalent to Windows 95 without
anything loaded except COMMAND.COM.
- DIR command now supports /S (search all directories)
as well as /A, /AS, /A-S, /AH, /A-H, /AR, /A-R, /AA,
/A-A options for file attribute support; Note that
DIR /A shows all files and directories whereas DIR
alone (without /A) shows all except system/hidden
ones as in a real DOS system (Wengier)
- DIR command now shows the real free disk space on
local drives. It is possible to limit this free space
for certain programs with the -freesize option of
MOUNT command. A new config option "freesizecap" is
added to change the behavior of this option (Wengier)
- DIR command fixed to show the volume label of the
drive you are listing, instead of always the current
drive (rderooy)
- Various improvements to DEL and COPY commands, e.g.
fixed the DEL /P option having no effect, and "DEL ."
deleted all files in the current directory silently;
the COPY command now asks for confirmation before
overwriting files, and it now supports /Y and /-Y
options to change this behavior, which can also be
set from the COPYCMD environment variable. (Wengier)
- Added or fixed help information and/or error messages
for some commands. (Wengier)
- Added support for DOS programs to communicate
with the clipboard in Windows builds. If the
"dos clipboard device enable" setting in
dosbox-x.conf is set to "true" or "full", a DOS
device (default name: CLIP$) will be added to
allow bidirectional communications with the
clipboard (e.g. "DIR >CLIP$" will write the
output to the clipboard, and "TYPE CLIP$" will
show the clipboard contents). Alternatively,
you can set it to "read" or "write" to allow
only read or write access for security reasons.
The DOS device name can also be changed with
the "dos clipboard device name" setting in
dosbox-x.conf. (Wengier)
- Added support for using the right mouse button
to copy and paste from the Windows clipboard; the
config option "clip_key_modifier" can be used to
change the keyboard modifier such as none, alt, ctrl,
shift, or disable this feature (default). (Wengier)
- Updated the PasteClipboard feature in SDL1 build
to support Unicode text translations; also fixed this
feature not working in SDL2 build. The config option
"clip_paste_speed" is added to speed up or slow down
the pasting speed for different DOS programs (Wengier)
- Support for DOSLIB2's w95sysrg/w95sysrs utils to
get/set system registry location in DOS 7+. (Wengier)
- Long filename support added, adapted from
the vDosPlus project. It will be enabled with
an initial DOS version of 7.0 or higher. (Wengier)
- Corrected return value when using option to
fake the installation of SHARE. (Allofich)
- Added code to EMS emulation to print specific
debug information when a PC-98 specific call is
made to remap segment B000h to either system
memory or video memory. I do not have enough
test cases or a setup to test what really happens,
so it will remain a debug message for now.
- Added dosbox-x.conf option to allow emulation of a
DOS environment that lacks ANSI.SYS. NOTE: The
option has no effect in PC-98 mode.
- INT 2Fh now responds to AX=1A00h which is an installation
check to report whether ANSI.SYS is resident.
- Added INT 21h debug logging for file I/O and general
INT 21h usage [patch by ognjenmi]. Added enables for
the logging which are off by default since the INT 21h
and file I/O logging are fairly noisy under normal
usage.
As a fork of DOSBox, DOSBox-X retains compatibility with the wide base of
DOS games DOSBox was designed for.
It also goes further, with a focus on accurate emulation of the hardware,
and many more ways to tweak and configure the DOS virtual machine.
