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.
5.0.0:
Incompatible changes
The bluetooth code has been removed without replacement. It was quite neglected over the years and likely not usable anymore. You can passthrough a dedicated USB bluetooth dongle to guests on most machines instead if you still need bluetooth in your guest.
The pc-0.12, pc-0.13, pc-0.14, pc-0.15 machines have been removed. Newer versions of the machine type should be used instead.
The "prep" ppc machine has been removed. The "40p" machine should be used now instead.
The "-virtfs_synth" option has been removed. You can use "-fsdev synth" together with "-device virtio-9p-..." instead.
The "-accel" and "-machine accel=" options are now incompatible with each other.
The deprecated "[hub_id name]" parameter tuple of 'hostfwd_add' / 'hostfwd_remove' has been removed. Use a "netdev_id" instead.
New deprecated options and features
The "-tb-size N" option has been deprecated. It is replaced by "-accel tcg,tb-size=N".
The virtio-blk SCSI passthrough feature (" -device virtio-blk,scsi=on") is deprecated. Use virtio-scsi instead.
The "r4k" mips machine has been deprecated. The "malta" machine should be used nowadays instead.
Support for using an AArch32 host system to run KVM guests has been deprecated (because the Linux kernel has dropped its support for this) and will be removed in a future version of QEMU. AArch32 guests on an AArch64 host are still supported.
Arm
Support for using an AArch32 host system to run KVM guests is now deprecated (because the Linux kernel has dropped its support for this) and will be removed in a future version of QEMU. AArch32 guests on an AArch64 host are still supported.

- Can now run KVM guests under a TCG emulated powernv machine
- Basic POWER10 support
Removed num-chips machine property, use -smp sockets=NN instead
Deprecated the compat= property on CPUs (it's been obsolete for a while with a pseries specific machine property)
Fixed a longstanding bug if using big-endian ABIv2 binaries with linux-user
Implemented new forms of the slbia instruction present in POWER9
RISC-V
The virt and sifive_u boards now have syscon device tree nodes, which allows the generic syscon drivers in Linux to control power/reboot.
The GDB stub now allows for D on rv32 and non-D on rv64.
The virt board now contains a Goldfish RTC.
Experimental support for version 0.5 of the draft hypervisor extension has been added.

- enable by specifying the cpu feature "ais=on"
QEMU now warns when it fixes up odd memory sizes for compatibility on compat machines
- Only done on compat machines to avoid breaking incoming migrations. If you can, fix up the memory size on old machines or switch to a machine type >= 5.0, which supports 1M increments
- The automatic fixup may be removed in a future version.
In a world of uncertainty, perhaps you can derive a little comfort
from MAME 0.220, our delayed release for the March development
cycle. This month has seen fixes for some old bugs in Final Star
Force, Ribbit! and Night Slashers, emulation of Crab Grab (the
other Game & Watch title with a colour overlay), the acquisition
of Solite Spirits (an early version of what became 1945k III), and
preliminary work on the Naruto TV game running on the XaviX 2
platform. There are some big software list updates this month,
including a lot of Apple II software aimed at North Dakota schools,
and the latest VGM music packs. Speaking of which, the VGM player
can now show pretty visualisations while you listen.
Newly supported peripherals include the Baby Blue II CPU Plus card
for PC compatibles, serial and CP/M modules for the HP 85 and HP
86, more sound and disk expansions for the TI-99 family, the CoCo
PSG cartridge, and a variety of 8-bit Acorn expansions. We’ve added
ROM dumps for a lot of synthesisers in this release, and while most
of them are not working yet, they’re there to tinker with if you’re
interested.
These are existing binaries, no way to fix them and not all of them are.

Update instructions for Fedora compilation
6.0.2 to 6.1: (March 22, 2020)
* IMPORTANT NOTES:
- Because of major event remapping changes, all remappings will be reset
to defaults; if you had custom mappings, they will need to be
re-entered again.
- Because of major internal changes, all state files are now invalid.
- Support for Windows XP has been discontinued as of this version. WinXP
is now completely out of support from Microsoft, so we are doing the
same.
* Major improvements to display mode handling in NTSC vs. PAL. The window
is now the same size for both modes, and scaling is applied to simulate
the height of scanlines (in PAL mode, there are more scanlines and hence
each is narrower). This more properly emulates how the display would look
on a real TV.
* Removed the 'Display_Height' property, changing it to 'Display_VCenter'.
This new feature, along with the display mode changes above, almost
completely eliminate having to manually tweak each ROM so that it will
not have part of the image cut off.
* Removed the 'Display_YStart' property and all automatic detection of
ystart. It caused problems on some ROMs, and was not the way a real
console would work anyway. Related to this, ROMs now load much faster.
* Major improvements to event remapping:
- Allow mapping of modifier-key and button-direction combinations
- Physical controllers can map the same action to different events on
different virtual controllers
- Many more events can be remapped
- Events can be filtered by type in UI
* Paths have been simplified:
- The following file/directory locations are no longer configurable
(statedir, nvramdir, cheatfile, palettefile, propsfile); they are
now all under the base directory
- Removed cfgdir; Distella config files are now placed with their
associated ROMs
- Added 'basedir' commandline argument, which allows to change the
base directory where almost all config-related items are stored;
related to this, discontinued the 'basedir.txt' functionality
- Added 'baseinappdir' commandline argument, which sets the base
directory to the application folder (Windows only for now); this
replaces the functionality of 'basedir.txt'
* Added automatic controller detection.
* Controllers can be changed during emulation (no ROM reload required
anymore).
* Added support for Light Gun controller.
* Added limited KidVid support (8, 9 and 0 start the games).
* Removed superfluous controller option 'PADDLES_IDIR'.
* Added configurable paddle dejittering.
* Key-repeat mode improved; entering Time Machine by holding down a key
combo continues to send events (previously, you had to release and then
press the combo again).
* Certain buttons in the UI can now be activated repeatedly by holding
down the mouse button (Time Machine, debugger step/trace/frame advance,
etc.)
* Added option to configure mouse double click speed.
* Added option to configure controller input repeat speed.
* Added high quality scaling.
* Made scanlines better aligned to scaling.
* Added 'HiDPI' mode, which scales the UI by 2x when enabled. This is
meant for 4k and above monitors, but can actually be used at any
lower resolution that is large enough to display the scaled UI.
* Fixed TIA 'Center' option, Stella now remembers the last windowed position.
* Added fractional (25% increments) TIA zooms.
* Removed 'tia.fsfill' option, replacing it with 'tia.fs_stretch'. This
new option allows to preserve TIA image aspect ratio in fullscreen
mode, or stretch to fill the entire screen.
* Added configurable 'Overscan' option for fullscreen modes.
* Fullscreen TIA modes no longer assume that desktop taskbars, etc
are present, hence they are scaled to the proper fullscreen size.
* Added option to display dialogs in screen corners.
* Added hotkey for sound on/off.
* Enhanced 'Command' menu to display current state and more commands.
* Added option to save and load all TimeMachine states at once.
* Added option to automatically load/save states when entering/exiting
emulation.
* Added option to change pitch of Pitfall II music.
* ROM Info Viewer size is not limited to fixed zoom steps anymore.
* ROM Info Viewer can now display multiple lines per property and the
bank switching type.

(thanks go to RomHunter for his tireless research in this area).
Related to this, updated the snapshot collection.
* Fixed 'Dancing Plate (Unknown) (PAL)' to use joystick.
* Fixed cheatcode handling in 2K and 4K ROMs.
* Fixed bug where ROMs smaller than 64 bytes were not recognized.
* Fixed bug where frying one ROM was continued with the next ROM.

more human-readable formats (not restricted to DOS 3-char length).
See the documentation for the new names.
* Fixed bug in DPC+ scheme; 'fast fetch mode' was enabled at startup,
when it should be disabled by default.
* Some more work on DPC+ playfield 'jitter' effect for certain older DPC+
driver versions; more ROMs are now detected properly. Special thanks
to SpiceWare for his research in this area.
* Added proper Retron77 port.
* Added proper libretro port, and fixed display for OpenGLES renderers.
* PNG/ZIP image support is now conditionally compiled into Stella.
All major ports (Linux/macOS/Windows) have it enabled by default.
