At least if you're using print-PLIST, which is kind of hard for
this package.

No version bump needed, since the combination would not build a package:
unexpected file share/applications/vice-org-x64.desktop.

Fasten your seatbelts and get ready for MAME 0.230! There are big
changes this month, but before we get to that, let’s highlight some
of the more routine additions. Several TV games featuring adaptations
of popular Hasbro board games are now supported, as well as a couple
of VTech systems featuring Dora the Explorer. Several electronic
toys and handheld LED game from Mattel and Invicta have been emulated
this month. There’s a big update for the Apple II software lists
this month, with clean cracks of lots of educational software from
MECC.
If you’ve been following along with development, you’re no doubt
excited about the new Yamaha OPM/OPN (YM2151, YM2203, YM2608,
YM2610, YM2610B, YM2612, and YM3438) sound emulation core. This
addresses numerous subtle and not-so-subtle issues, particularly
in Sega and Data East games. Windy Fairy and Jennifer Taylor have
continued to improve MAME’s support for Konami rhythm games, making
beatmania IIDX, Beatmania III, Keyboardmania and ParaParaParadise
games playable. Thanks to Happy, a couple more graphics issues with
the Hyper Neo Geo 64 have been fixed.
There’s been a lot of work on the Apple IIgs and 68k Mac drivers
this month. As well as the flood of machines promoted to working,
Apple 3.5" floppy support has been revolutionised, and improvements
to ADB GLU microcontroller simulation make the IIgs control panel
usable. On the console side, save EEPROM support has been fixed
for several Mega Drive games.

Changes since 0.31:
Controller Improvements & Rumble Support
This release focuses on Controller Support & Improvements.
Please replace your old config.xml file when upgrading to this release.
* [Controllers] Basic rumble support can now be enabled from the CONTROLS
menu. The strength can be adjusted. The code that controls the rumble is
identical to that of the upright arcade machine motor shaker. The option
will only show in the menu if your controller is supported.
* [Controllers] Auto-detection and assignment of controller buttons and axis
should be much improved. I will update the manual to call out the default
controls in due course. (Right trigger = accelerate, Left trigger = brake,
Start = Start, Back = Menu, A = Gear Change, X = Change View, Y = Coin).
These can be redefined as desired.
* [Controllers] D-Pad can be used in menus.
* [Menus] Gamepad/Joystick settings has its own menu.
* [Menus] Ensure that 'A' button on controllers can be used to select items.
Analog accelerate is now only used when run via original arcade cabs as
it's not optimal.
* [Rom Loader] Sped up CRC32 based loading by using a Hashmap. It was
reportedly slow when used over a network.
* [Rom Loader] It is possible to switch back to the old filename loading
system via a setting in config.xml
* [Config] It is now possible to change and configure the location of the
'res' directory.

Changes since 0.3.2019102:
Maintenance Release
This release focuses on upgrading the libraries and compilation tools CannonBall
uses, as I hadn't maintained the codebase in a number of years. Most of these
changes will be invisible to most users. Right now, I'm trying to get the house
in order as opposed to add lots of wild new features! :)
* [audio] Audio updates at the correct rate and resolves the longstanding
issue with music and sound being very slightly 'off'
* [roms] ROMs are now read by CRC 32 value. Filenames no longer matter - so
long as they are present they can be renamed to anything.
* [roms] Fixed expected Z80 rom file length
* [controls] Start Button behaviour less 'sticky' and buggy
* [controls] Analog axis for accelerate and brake can now be configured via
the in-built menu system
* [menu] Reduced delay when scrolling through menu with analog controls
* [config] ROMs and save data can be relocated to separate locations
* [bug fix] Time Trial mode no longer crashes if used as the first mode played
* [timing] Code tries to use V-Sync for timing OR internal timing, as opposed
to both at once
* [source] SDL 2 used by default. SDL 1 removed from codebase. This appears to
have fixed compatibility bugs for some people
* [source] Added compatibility for upcoming SmartyPi hardware (Pi 4 based) to
run on original arcade hardware
* [source] A general clean-up in many areas

would select the nvmm library when it wasn't disabled that later was not
found.
While here, also fix a curses issue introduced in version 5.2.0nb2; it would
not find the appropriate library.

# 1.9.0
- AUTOCONFIG: Ensure correct directory is used when saving autoconfig profiles
- BLUETOOTH: Add a Bluetooth driver (Lakka-only for now)
- CHEATS: Fix for wrong number of remaining cheat search matches on some machines
- CHEEVOS: Option to play sound on achievement unlock.
- CHEEVOS: Upgrade to rcheevos 9.1
- CHEEVOS: Restore display of unlocked achievements across hardcore modes
- CHEEVOS: Hash buffered data when available
- CHEEVOS: Fix 'Auto Save State freezes RetroArch while Cheevos is enabled'
- CORE OPTIONS: Pressing OK (or clicking/tapping) on a 'boolean toggle' core option no longer opens a drop-down list. The value now toggles directly, just like boolean options everywhere else in the menu
- CORE OPTIONS: Toggling an option that changes the number of core options being displayed (i.e. things like `Show Advanced Audio/Video Settings) no longer resets the navigation pointer to the start of the list
- CORE OPTIONS: Before, RetroArch would identify core option values as being 'boolean' if they had labels matching the specific strings enabled or disabled. Most core devs would abide by this, but not always... As a result, we sometimes would end up with misidentified values, with all kinds of Enabled, Off, True, etc. strings littering the menu, in place of proper toggle switches. All boolean-type value labels are now detected, and replaced with standard ON/OFF strings.
- CLI: A new command line option --load-menu-on-error has been added
- CRT: On the fly CRT porch adjuments - these changes allow a user to adjust how the porch algorithm generates the 15khz/31khz output. Giving the ability to change over/under scan.
- CONFIG FILE: Optimise parsing of configuration files
- DRIVERS: Implemented protection to avoid setting critical drivers to nothing thus preventing the user from locking him/herself out of the program
- EMSCRIPTEN: Fix input code to ignore unknown keys
- FFMPEG CORE: Prevent seeking past the end of files (hang fix)
- FILE I/O: VFS and NBIO interfaces will now use 64-bit fseek/ftell where possible, should allow for reading/writing to files bigger than 2GB
- INPUT MAPPING/REMAPPING: Add input remap drop-down lists
- IOS: Fixed iOS 6 version
- IOS: Hide the home indicator as it obscures the content too frequently
- IOS/METAL: Metal video driver now works on RetroArch iOS
- IOS/METAL: Support getting video metrics to support proper touchscreen interactions
- LOCALIZATION: Updates for several languages (synchronized from Crowdin)
- MEMORY/LINUX/ANDROID: Fix reporting of free memory
- MENU: Enlarged INT/UINT selection limit from 999 to 9999
- MENU: Fix cursor forced to first entry after displaying lists
- MENU: Make Notification Font option visible when Graphics Widgets are enabled
- MENU/RGUI: Add optional 'toggle switch' icons
- MENU/WIDGETS: Add optional widget-based 'load content' launch feedback animation
- MENU/WIDGETS: Make notification font size option visible when graphics widgets are enabled
- ODROID GO ADVANCE: Video driver - fix race condition with RGUI callback
- PLAYLISTS: Change playlists to use dynamic arrays. Instead of a fixed initial 12MB memory allocation (99999 * 128 byte (on 64bit arch)), use a dynamically growing array
- PLAYLISTS: Playlist base content directory paths - portable playlists
- PLAYLISTS/SEARCH: Enhanced playlist search functionality
- PLAYLISTS/DATABASE: Add 'Explore' view
- PLAYLISTS/DATABASE/EXPLORE: Show system icons in explore view
- PS2: Improve FPS Limiter
- RUNAHEAD: Prevent runahead from being disabled *permanently* when an error occurs
- SHADERS/SLANG: Increased Slang max Parameters, Textures & Passes
- VIDEO FILTERS/BLARGG: Make Blargg_snes filter customizable

It’s been an eventful month, culminating in the release of MAME
0.229 today. One change that you’ll notice straight away is that
the “64” suffix is no longer added to the file name for 64-bit
versions of MAME. If you’re unsure, you can see the data model at
the end of the window title.
One very elusive Argentinian title has finally made it into MAME
this month. We’re very proud to present Ms PacMan Twin, an extensive
hack of Ms. Pac-Man with simultaneous two-player cooperative
gameplay. Another rarity you can now experience is Midway’s unreleased
Power Up Baseball – the NBA Jam of baseball. On the topic of
prototypes, Wayne Gretzky’s 3D Hockey Fatality Edition is now
supported.
Several TV games for preschool age children from JAKKS Pacific’s
Sharp Cookie line have been dumped and emulated, featuring popular
characters like Dora the Explorer, Scooby-Doo, Spider-Man and Thomas
the Tank Engine. Travelling back a little, Mattel’s representations
of Basketball, Hockey, Soccer, and Tag as electronic toys are now
supported. Elektronika Autoslalom has arrived from Russia (with
love). Another batch of JPM IMPACT fruit machines have been promoted
to working this month, making use of new artwork engine features
for their internal layouts.
Updates to the Win32 and Qt debuggers add a context menu to debugger
views with an option to copy visible text to the clipboard, improve
behaviour when views are scrolled to the bottom, and fix a crash
when right-clicking some memory views. We’re lucky enough to have
received another shader update from cgwg, improving the appearance
of the popular crt-geom and crt-geom-deluxe effects. We’ve added
support for the NEC/Renesas V850 family to unidasm.
That’s all we’ve got time for here, but there are lots of software
list updates, newly dumped bootlegs, bug fixes, and other enhancements.

Changelog:
IMPORTANT NOTE: in this release we have switched our build system to internally use Meson. Building should be broadly unchanged for most users, but please see the [[#Build Information|Build Information]] section of the changelog for details and for '''the list of new [[#Build Dependencies |build dependencies]] you now need to install'''.
== System emulation ==
=== Incompatible changes ===
=== New deprecated options and features ===
Consult the [https://www.qemu.org/docs/master/system/deprecated.html "Deprecated Features"] chapter of the QEMU System Emulation User's Guide for the full list of historically deprecated features/options.
In particular, note that the Unicore32 and lm32 guest support have been deprecated and will be removed in a future version. They are now only built if explicitly enabled in --target-list.
=== 68k ===
=== Alpha ===
=== Arm ===
* ARMv8.2 FEAT_FP16 (half-precision floating point) is now implemented for AArch32 emulation (AArch64 already supported this)
* AArch64 BTI is now supported in linux-user emulation mode (it was already implemented for system emulation)
* The SMMUv3 model now supports SMMUv3.2 range invalidation
* The sbsa-ref board now has an embedded controller model for guest powerdown and reboot requests
* The sbsa-ref board now has an SBSA-compatible generic watchdog device
* The Raspberry Pi boards now emulate the CPRMAN clock manager device
* Support for KVM on 32-bit host CPUs (deprecated in 5.0) has now been removed. (32-bit KVM guests on 64-bit hosts remain supported.)
* Two new board models in the mps2 family: mps2-an386 (Cortex-M4 based) and mps2-an500 (Cortex-M7 based)
* New board models in the raspi family: raspi3ap (the Pi 3 model A+), raspi0 (the Pi Zero) and raspi1ap (the Pi A+)
* New Nuvoton iBMC board models: npcm750-evb, quanta-gsj
* The 'max' CPU now implements a 48-bit physical address size when using TCG emulation.
* The 'virt' board supports kvm-steal-time (enabled by default for virt-5.2 and on) so that a guest OS can account for time when its CPUs were not running due to the host not scheduling the corresponding vCPU threads.
=== AVR ===
=== HPPA ===
* Added power button emulation
* Boots NetBSD
* Boots old Linux CDs, e.g debian-0.5 and debian-0.6.1
* Artist framebuffer fixes when running dtwm on HP-UX

=== Microblaze ===
=== MIPS ===
=== Nios2 ===
=== OpenRISC ===
=== PowerPC ===
* The pseries machine now respects the nvdimm= machine option (previously NVDIMMs could be attached even with nvdimm=off)
* The pseries machine now does a better job of reflecting the user specified NUMA distances in the guest (PAPR limitations mean it's still a pretty poor approximation, though)
* We now fail more gracefully if attempting to run an HPT guest as a nested KVM guest (which isn't supported in the kernel for now)
* spapr_vscsi should now properly report that it does not support hotplug
* The pnv machine now allows firmware images up to 16MiB, instead of just 4 MiB (this matches the limit on physical FSP machines)
=== Renesas RX ===
=== Renesas SH ===
=== RISC-V ===
* Improvements to the Ibex (OpenTitan) PLIC
* OpenSBI v0.8 included by default

* Fix for crash seen when running 'poweroff' command on virt machine
* virt and sifive_u machines allow a custom dtb argument
* Support for migrating machines
=== s390 ===
* KVM: The diagnose 0x318 instruction is now supported.
* TCG: More instructions that were introduced with the z14 are now emulated.
* zPCI: vfio-pci devices now report real hardware features for functions, instead of emulated values (needs host kernel support.)
* virtiofs is now also supported on s390x via ccw
=== SPARC ===
* sun4m: fix panic when booting NetBSD with the TCX framebuffer
* sun4u: fix for sabre PCI IRQs being lost due to memory overflow
=== TileGX ===
=== Tricore ===
=== x86 ===
* A new KVM feature which improves the handling of asynchronous page faults is available with ''-cpu ...,kvm-async-pf-int''. This requires Linux 5.8.
=== Xtensa ===
* DFPU coprocessor with single and double precision floating point opcodes is now supported
* NMI is now supported
=== Device emulation and assignment ===

==== NVDIMM ====
==== NVMe ====
* Add support for mandatory features of version 1.3 of the NVM Express specification
* Add support for the Abort, Asynchronous Event Request and Get Log Page commands
* Add support for Scatter Gather Lists (supported descriptors: Data Block, Bit Bucket, Segment and Last Segment)
* Allow the device to be configured with the "Admin Only" command set
* Support multiple namespaces through the new nvme-ns device

==== 9pfs ====
* Significant [https://lists.gnu.org/archive/html/qemu-devel/2020-01/msg05539.html performance improvement of Treaddir] requests.
* A performance warning is now logged on host side if 'msize' is set to a very small value, which especially includes Linux 9P clients not having any user specified 'msize' parameter at all. Simply setting 'msize' (on client/guest side) to any value larger than 8192 will cause the warning to disappear. See [https://wiki.qemu.org/Documentation/9psetup#msize msize documentation] for details.
==== virtiofs ====
* virtiofsd xattrmap option to allow the host to see different xattr names to the guest
* virtiofsd alternate sandbox option for environments where pivot_root isn't available
* virtiofsd 'submount' mechanism (requiring newer guest kernel) allows different host mounts to be seen as separate submounts in the guest, avoiding inode clashes.
==== Semihosting ====
=== Audio ===
=== Character devices ===
* Inverted logic in QAPI handling the "tight" option for abstract UNIX sockets was fixed.
* The QAPI schema now only reports support for abstract UNIX sockets on platforms where it is available (Linux).
=== Crypto subsystem ===
==== experimental qmp interface ====
=== GUI ===
* Spice: add support for SIDE and EXTRA mouse buttons. Improve HiDPI, set physical dimensions of client monitors.
* Build spice and opengl as modules
=== GDBStub ===
=== Host support ===
=== Memory backends ===
=== Migration ===
* A new 'block-bitmap-mapping' migration parameter is added, allowing finer control of which bitmaps to migrate, even when node names differ between source and destination.
* Migration over 'vsock' is now allowed, for nested environments or hosts with hardware that looks like a vsock.
* A new 'calc-dirty-rate'/'query-dirty-rate' call gathers an approximation of the rate at which the guest is dirtying RAM and thus gives an idea about whether precopy migration is likely to proceed.
* The default migration bandwidth has been increased to 1Gbps; users are still encouraged to tune it to their own hardware.
* TLS+multifd is now supported for higher bandwidth encrypted migration.
* Migration with dirty bitmaps has several bugs fixed.
=== Monitor ===
==== QMP ====
* Command block_resize no longer blocks the main loop.
==== HMP ====
* Command block_resize no longer blocks the main loop.
=== Network ===
=== Block device backends and tools ===
* qcow2 files now support extended L2 entries that allow subcluster-based allocation (enable with <code>extended_l2=on</code> when creating the image).
* Using qemu as an NBD client has fewer scenarios where network timeouts stall guest execution
* More explicit errors are reported when use of O_DIRECT fails
* The 'block-export-add' QMP command has been introduced to support qemu-storage-daemon, and replaces the now-deprecated 'nbd-server-add' command.
* The 'vhost-user-blk' export type has been added, allowing qemu-storage-daemon to act as a vhost-user-blk device backend.
* qemu-nbd now supports multiple '-B name' options for exposing multiple dirty bitmaps at once; it also supports a new '-A' option for exposing the new "qemu:allocation-depth" metadata context over NBD.
=== Tracing ===
* Add support of dtrace backend on macOS
=== Miscellaneous ===
* The roms/edk2 submodule and the bundled edk2 binaries have been updated to [https://bugs.launchpad.net/qemu/+bug/1852196 edk2-stable202008].
== User-mode emulation ==
* ppc64abi32-linux-user is deprecated and only built when explicitly enabled in--target-list
* tilegx-linux-user is deprecated and only built when explicitly enabled in--target-list
* better reporting when we can't mmap the guest_base we want on systems without MAP_FIXED_NOREPLACE
== TCG ==
== Guest agent ==
* New commands: <code>guest-get-devices</code>, <code>guest-get-disks</code> & <code>guest-ssh-{get,add,remove}-authorized-keys</code>
* Support <code>guest-get-fsinfo</code> for non-PCI virtio devices, too
== Build Information ==
* The build system is now partly based on Meson. However, building is still done with ''configure'' and ''make'' as in previous versions of QEMU.
* Binaries for emulators are placed in the root build directory, for example as ''qemu-system-ppc'' instead of ''ppc-softmmu/qemu-system-ppc''. Symbolic links from the old binary are preserved to simplify the transition.
* In-tree builds are not supported anymore. The build system will try to cater for ''./configure && make && make install'' by building QEMU in a directory named ''build'', but you are encouraged to switch to out-of-tree builds instead.
* ivshmem-client and ivshmem-server are not installed anymore. They are merely examples, and not to be used in production.
* QEMU installations are now relocatable. For example, if QEMU is configured with ''bindir=/usr/local/bin'' and ''datadir=/usr/local/share'', when QEMU is launched as ''/opt/local/qemu-5.2/bin/qemu-system-x86_64'' it will look automatically for data files in ''/opt/local/qemu-5.2/share''. Note that directories configured outside the prefix (as is often the case for ''/etc'' and ''/var'') will not be relocated! Previously this was done only under Windows and only for emulators.
=== Python ===
* Python 3.6 or newer is now required to build QEMU.
=== GIT submodules ===
=== Container Based Builds ===
* All Debian 9 based cross-compiler containers have been updated to Debian 10
=== Build Dependencies ===
* Ninja 1.7 or newer is now required to build QEMU:
* '''$ apt-get install ninja-build''' (Debian/Ubuntu and derivative distros)
* '''$ dnf/yum install ninja-build''' (RHEL/Fedora/CentOS and derivative distros)
* '''$ brew install ninja''' (macOS with HomeBrew)
* '''$ pkg install ninja''' (FreeBSD)
=== Windows ===
* qemu-nbd is now built on mingw, and works for simple cases even if it can't duplicate the full functionality available on Unix systems
=== Testing and CI ===
* a new script can wait on gitlab to finish with a pass/fail status (scripts/ci/gitlab-status)

QEMU is a FAST! processor emulator using dynamic translation to achieve
good emulation speed, QEMU has two operating modes:
* Full system emulation. In this mode, QEMU emulates a full system
(for example a PC), including a processor and various peripherals.
It can be used to launch different Operating Systems without rebooting
the PC or to debug system code.
* User mode emulation (Linux host only). In this mode, QEMU can launch
Linux processes compiled for one CPU on another CPU. It can be used
to launch the Wine Windows API emulator or to ease cross-compilation
and cross-debugging.
This package contains Qemu 5.1.0 with NetBSD NVMM support.

* All pkgsrc patches are included by upstream.
Changelog:
OpenBSD/luna88k can now run in the emulator (with root-on-nfs), and there
is now tap device support for networking contributed by Jason Thorpe.
