DOSBox-X v0.83.19 (2021/11/01)

DOSBox-X v0.83.19 (2021/11/01) 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:
Reorganized the "List network interfaces" and "List
printer devices" dialogs (under the "Help" menu) to
allow the use of scroll bars. (Wengier)
Added menu option "Reset TTF color scheme" to reset
the current color scheme for TTF output. (Wengier)
Added config option "righttoleft" in [TTF] section
which when set to "true" will cause DOSBox-X to
display text from right to left (instead of left to
right) for the TTF output. It can also be toggled
from the menu ("Video" => "TTF options" => "Display
text from right to left"). (Wengier)
Added config option "vga fill active memory" which
when set to "true" will fill inactive video memory
regions with RAM rather than mapping them as empty.
This allows the ETen Chinese DOS system (倚天中文系統)
3.5/2000 (e.g. ET16V and ET24VA) to run. (Wengier)
Added config option "middle_unlock" ([sdl] section)
to control whether to unlock the mouse with middle
mouse button click. (Wengier)
Added config option "dosvfunc" in [ttf] section to
support DOS/V applications when country information
is set to Japan in TTF output. (nanshiki)
Added "VTEXT" command to view or change the current
V-text mode for the DOS/V emulation. Also improved
the font support for 24-pixel font DOS/V mode, such
as supporting HZK24? fonts for Simplified Chinese
DOS/V mode and STDFONT.24 from ETen Chinese system
for Traditional Chinese DOS/V mode. If a Chinese
font is specified via "fontxdbcs", "fontxdbcs14" or
"fontxdbcs24" options, it will be loaded before
system font even with "getsysfont=true". (Wengier)
Commands like 80x25, 80x43, ... now use internal
function for better compatibility with the TrueType
font (TTF) output. (Wengier)
MODE command without a parameter will now print the
current lines/columns instead of usage. (Wengier)
INTVEC debugger command now correctly outputs
addresses when in protected mode. (Allofich)
Fix horizontal lines in the debugger window being
rendered as unrelated characters in some code
pages. (Allofich)
INT 21 AX=4B03 now sets AX to 0000 like MS-DOS
does. Fixes missing music in "聊齋誌異之幽谷傳奇"
(Liáozhāi zhì yì zhī yōugǔ chuánqí) (Allofich)
Use 0x1E to 0x3E for the keyboard buffer of the CGA
machine, which fixes the controls locking up in the
PC booter version of Apple Panic. (Allofich)
Allowed machine types "pcjr_composite" and
"pcjr_composite2", similar to "cga_composite" and
"cga_composite2", instead of having to switch the
composite type manually. (Wengier)
If machine is PCjr, place PC BIOS reset code at
F000:0043 to match that of the real BIOS.
Fix PCjr NMI handler to load DS with segment 0x0040.
Fixes crashes in SHAMUS. (Allofich)
Fix PCjr NMI handler to use 8086-level instructions
when loading DS with segment 0x0040 so that it
works properly with cputype=8086.
Remove useless check for signed divide quotient
of 0x80/0x8000/etc. (the result was -0x80/0x8000/etc
anyway. Add code to check specifically for these
values after signed divide if cputype=8086 and
trigger divide overflow exception, to match behavior
described for the 8086 processor.
Modify exception handling so that for cputype=8086
the return address for an exception handler points
at instruction after fault location.
Fix IDIV instruction incorrectly raising a divide
error exception for some borderline values. Fixes
Microsoft Flight Simulator. (Allofich)
IBM PC BIOS emulation fixed to place key pieces of
code and entry points at fixed legacy locations
required by some older DOS games, instead of
by dynamic allocation. Added code to BIOS allocation
to reserve F000:E000 or higher for fixed allocation
and force dynamic allocation below that address to
prevent further conflicts should others submit
pull requests for additional fixed locations. This
fixes some games like "聊齋誌異之幽谷傳奇" (Liáozhāi
zhì yì zhī yōugǔ chuánqí) which appear to assume
some of these fixed BIOS addresses and will
crash if they are wrong.
Added tool EMSMAGIC.COM as alternative EMS manager,
which can be dynamically installed or uninstalled
with the setting ems=false. (Wengier)
If a program is provided in the command-line when
launching DOSBox-X, it will now be executed after
any commands in the [autoexec] section by default.
A command-line option "-prerun" is added to force
the program run before any commands in [autoexec]
section like before. (Wengier)
Added auto-detection for single-wide DBCS-encoded
characters for the TTF output (non-PC98). (Wengier)
Improved the menu option "Restart DOSBox-X with
language file..." (under "Main") for switching
between DBCS languages. (Wengier)
Disabled the Alt+F4 key for closing the DOSBox-X
window in MinGW SDL2 builds. (Wengier)
Fixed program or config file containing Unicode
characters passed from command-line when launching
DOSBox-X in Windows SDL2 builds. (Wengier)
Fixed issue with DELETE key in PC-98 mode. (Wengier)
Fixed COLORS config option (in [ttf] section) not
working in the previous version. (Wengier)
Fixed issues after resetting the virtual machine
when using DBCS language files. (Wengier)
Fixed some issues related to system IME support for
CJK (Chinese/Japanese/Korean) languages, for both
Windows SDL1 and SDL2 builds. (nanshiki & Wengier)
Fixed bugs in the region memory allocator C++ class
that claimed the entire free block even if the
size wanted was smaller. Added field to remember if
the allocated block was allocated for fixed or
dynamically allocated memory. Cleaned up allocator
code and removed redundancy.
Fix SELINFO command not showing output correctly
in the debugger window. (Allofich)
Better CMOS register B and C emulation. (Allofich)
Integrated commits from mainline (Allofich)
Support for DMF floppy disk images.
Zero-out DX in EXEC overlay command.
Improve stack check for wrap-around cases.
Change to misc_output for SVGA_S3Trio.
