DOSBox-X v0.83.8 (2020/11/31)

DOSBox-X v0.83.8 (2020/11/31) 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 support for scalable TrueType font (TTF)
output for text-mode programs. Set "output=ttf"
and optionally a monospaced TTF font (such as
consola) with config option "ttf.font" to use it.
Lines and columns can be specified with config
options "ttf.lins" and "ttf.cols", and the cursor
can be made blinking with the option "ttf.blinkc".
The config options "ttf.ptsize" and "ttf.winperc"
can be used to set the TTF font size and window
percentage respectively. If you specify a TTF font
size with "ttf.ptsize" then "ttf.winperc" will be
ignored. You can also specify a word processor
(WP=WordPerfect, WS=WordStar, XY=XyWrite) for the
on-screen text-style and 512-character font (WP)
features. When using the TTF output DOSBox-X will
temporarily switch to a different output when a
graphical mode is requested (or when trying to take
a screenshot); the TTF output will be auto-switched
back later), which can be customized via config
option "ttf.outputswitch" (which defaults to auto).
Menu items in the "Text-mode" menu group (under
"Video" menu) have been expanded to support TTF
options such as increasing/decreasing the TTF font
sizes and on-screen text style toggling (including
bold, italics, underline and strikeout). You can
also select a TTF font to use at run-time with the
"Select TrueType font (TTF)" menu option. (Wengier)
Added the "Load mapper file..." menu option (under
"Main") to select and load a DOSBox-X mapper file
at run-time. Be sure to select a SDL1 mapper file
for SDL1 builds, and similar for SDL2. (Wengier)
You can now select a host key from the menu (under
"Main") including Ctrl+Alt, Ctrl+Shift, Alt+Shift,
or use the mapper-defined host key as in previous
versions (which default to F11 on Windows and F12
otherwise). A config option "hostkey" is added so
that you can specify it from config file. (Wengier)
Pasting text from the clipboard on macOS SDL1 build
is now supported like Linux SDL1 build. (Wengier)
Added support for ARM-based Apple M1 MacBook. The
dynamic core now works on ARM-based macOS systems.
SDL1 builds updated to use newer audio APIs on the
macOS platform so that the audio works once again
when compiled and run on macOS 11 (Big Sur). Prior
to the change, ancient versions of the API dating
back to the mid 2000s were used which no longer
work on Big Sur.
DOSBox-X will now look for the config file (i.e.
dosbox-x.conf/dosbox.conf) and the mapper file in
the directory containing the DOSBox-X executable
too if the config or mapper file cannot be found
in the DOSBox-X working directory. (Wengier)
The system menu in Windows SDL1 builds is now also
available for Windows SDL2 builds, and menu items
"Reset font size", "Increase TTF font size" and
"Decrease TTF font size" are added. (Wengier)
Enhanced the mapper editor interface to allow more
keyboard shortcuts to be added, shown in multiple
pages in the mapper, navigable with the "Previous
Page" and "Next Page" buttons. The text in the
grids are now longer and clearer too. The default
shortcuts for a few items are changed to use the
Host key style (e.g. Host+S and Host+L for saving
and loading states respectively). (Wengier)
Added menu item "List network interfaces" under
"Help" menu to list network interfaces in the host
system for the NE2000 feature. (Wengier)
Added menu group "DOS commands" under "Help" menu
to display the help content for the selected DOS
shell command (DIR, CD, etc). (Wengier)
Configuration Tool now provides the option to save
to the primary or user config files. (Wengier)
Certain config options (e.g. doublescan) that were
marked as advanced options are now general config
options and will appear in dosbox-x.reference.conf
apart from dosbox-x.reference.full.conf. (Wengier)
Added config options "saveremark" (default: true)
and "forceloadstate" (default: false) in [dosbox]
section which can be used to control if DOSBox-X
should ask users to enter remarks when saving a
state or show warnings when loading a saved state
if there is a mismatch found. (Wengier)
The config option "pixelshader" is moved from the
section [gui] to [render] so that it will be in the
same section as the option "glshader". (Wengier)
Added menu item "Select OpenGL (GLSL) shader..." to
allow OpenGL shader switch from the menu, just like
the function for Direct3D pixel shaders. (Wengier)
Added menu item "Show IDE disk or CD status" under
"DOS" menu to show the current assignments (disk or
CD image) of the IDE controllers. (Wengier)
Fixed IDE CD assignment may not be reset when soft
reboots are activated from guest systems. (Wengier)
The program 80x43.COM is added into the ZIP package
TEXTUTIL.ZIP on the Z drive. You can also change
current text screen to the 80x43 mode from the menu
group "Text-mode" under "Video" menu. (Wengier)
Enhanced MODE command so that you can change the
number of columns and lines in the screen with the
syntax "MODE CON COLS=c LINES=n" (c=80 or 132, and
n=25, 43, 50, or 60). The command "MODE CON" will
show the current number of columns and lines in the
screen as in a real DOS system. (Wengier)
Added FLAGSAVE command for the save state feature
to flag (mark) one or more files to be saved and
loaded. Type "FLAGSAVE /?" for more information on
this command. (PogoMan361 and Wengier)
Enhanced A20GATE command to show the current status
of the A20 gate when no parameter is given, along
with other small improvements. (Wengier)
INT 21h DOS=HMA emulation, to enable the A20 gate,
and autoa20fix, to disable the A20 gate, now checks
whether the CPU is running in virtual 8086 mode.
If vm86 detected, the code will control the A20
gate by calling the XMS interface instead of direct
reading/writing via port 92h. This consideration
is required for autoa20fix to cooperate with
Microsoft Windows 3.1. Note that Windows 3.1 does
not virtualize port 92h. If it did, this workaround
would not be necessary.
Added -a option to LOADFIX command which will auto
allocate enough memory to fill lowest 64KB memory
instead of using exactly 64KB memory. (Wengier)
Added autofixwarning option (true by default) which
allows user to silence the messages when DOSBox-X
tries to auto-fix "Packed file is corrupt" error
when running a program with this issue. (Wengier)
Added autoa20fix option (enabled by default). This
option when enabled attempts to resolve EXEPACK
"Packed file is corrupt" errors by temporarily
disabling the A20 gate and running the program
again. This may provide better support for affected
DOS applications than the LOADFIX option. If both
autoa20fix and autoloadfix are set, then autoa20fix
will be tried first, and if it did not work then
autoloadfix will be tried next.
The autoloadfix config option changed to allocate
only enough memory to keep the executable above the
64KB boundary, instead of blindly allocating 64KB.
Fixed menu items "Rescan drive" and "Swap disk" in
"Drive" menu being reversed. (Wengier)
Fixed CD audio issue with the game "The Secret of
Monkey Island" when talking to the pirate in Scumm
Bar by adapting the patch that fixes it. Thanks
kcgen for the fix logic. (Wengier)
Added support for MAME CHD CD images. You can now
mount CHD images with IMGMOUNT command, or from the
Drive menu. Based on libchdr library and the work
of the user whocares010. (Wengier)
Updated FLAC/MP3/WAV CD-DA decoder libraries to the
latest versions (versions 0.12.22, 0.6.19, 0.12.14
respectively). Thanks to mackron & kcgen. (Wengier)
