The VICE v3.9 emulator Commodore 64 has been released.

General
- rewritten joystick mapping and -input system. Both the SDL and GTK versions share common code now, have the same features, and can use the same mapping files. However, unfortunately we ran out of time and could not implement a related UI in the GTK port yet - which means you will have to create and/o install the required mapping file manually like this, if the (very simple) default mapping does not work for you:
 1. find a matching SDL mapping file in DATA/C64. If none of the existing ones matches your controller, you may create one yourself (either manually or using the SDL port)
 2. rename the mapping file to "gtk3-joymap-.vjm" - for example gtk3-joymap-C64SC.vjm
 3. copy the resulting file to the (current) default location:
    Windows: the bin directory (where the .exe resides)
    Linux: $HOME/.config/vice/
- Interrupt logic fix: Only when the first IRQ source becomes active, the CPU sees the IRQ input line go active; on additional ones, no change is visible. So most of the actions that are done should only be done when the first IRQ source becomes active, and not on additional ones
- added an option that allows to skip soundchip emulation in warpmode (to increase performance, at the cost of some accuracy)
- reSID: scale down filtered voices on 6581
- reSID: scale and clip volume by an arbitrary factor, makes 6581/8580 nearly the same volume
- reSID: implement DAC leakage
- reSID: fix uninitialized var in old filter
- reSID: Fixed the 8580 filter voltages, now the values really make sense
- CIA: always toggle AM/PM flag when writing 12 o'clock time, no matter if this is a change to the hours register or not
- cleanup of the userport system, devices that do not (and can not) work are no more available for a particular machine
- Added C64/C128/SCPU64 palette file created by Kim Lemon to allow for consistency in screenshots for lemon64.com
- fixed handling of warp mode while movie recording is active
- improved ZMBV recording, now handles accurate fractional FPS
- fixed recording with external ffmpeg executable
- fixed polling POTX/POTY when no mouse is active
- added Chalkboard PowerPad emulation
- fixed Rushware Keypad
- fixed Cardco Cardkey keypad
- fixed Atari CX21 Keypad
- fixed SNES pad's raw data
- fixed mapping for keypads attached to joyports
- fix: WOJ Adapter bits where inverted
- removed support for right and middle button with Amiga and AtariST mice - These connect POT lines with GND when pressed, and are open if not, which the CBM machines can not detect (since there is no pullup resistor)
- Allow CMD smartmouse time/date to be read and written even if the mouse is not grabbed
- When writing .tap values, add the remainder of the current value to the next, so overall tap length will be correct
- do not automatically 'press play' when attaching a t64 image, we don't do this for taps either
- 'press STOP' when detaching a tap image
- Fix default tape header type (t64) for vic20 and c128 (it should be type 3, ie absolute)
- Fix the 'load to basic start' autostart option for tape
- Reworked the log system. logging to stdout and to an actual file can coexist now, each can be selected separately
- (Optional) support for colors in log messages
- Made ANE/LXA logging options available in all emus, except SCPU
- VICII: init color ram at powerup
- fsdevice: fixed file name pattern matching
- fsdevice: Directory loading of "$:" was loading the full directory but should have matched no files at all. It is actually a degenerate case where you specify an empty pattern and that matches no names
- fsdevice: make the first 'line number' in the directory 1 instead of 0. This is the partition number on cmd devices, and apparently the c64os setup chokes on it being 0
- fixed DigiMAX DAC addresses to make stereo replay work correctly
- RAMLINK: IO1 wouldn't bet setup properly after RAMLINK was turned back on
- fixed RTC core (RTC on CMD FD/HD and RAMLink)
- save 'jammed' status into snapshot for each cpu

Buildsystem
- make configure bail if pkg-config isn't found
- generate linker map files with `--enable-debug`
- configure: barf if `--enable-gtk3ui` is combined with `--without-zlib`
- Added "Game" and "Emulator" categories in the .desktop file template used by the `--enable-desktop-files` configure switch. Should fix issues with desktop environments not showing the icons after a `make install`

C64 fixes
- extended DQBB support, support 16-256k RAM, support C128 mode
- added support for UC1/UC15/UC2 cartridges
- added support for BMP Data Turbo 2000 cartridge

- Fix: Z80 can not see charrom in c128 mode, but it can in c64 mode
- added WZ reg for improved bit 3 and 5 status register results. x128 Z80 now passes ZEXALL
- RAMlink: also exposes open-circuit when internal function roms are off
- VDC memory is now properly accessed when memory configs differ; vdcdump runs in 16KB mode

VIC20 fixes
- tweak ram init pattern, this makes some known cases that rely on it work (AE, Jelly Monsters)
- make the 'exp' command work in the monitor
- added support for 'rabbit tape' cartridge
- added support for 'Super Expander' cartridge
- added support for 'Mikro Assembler' cartridge
- added missing 'bin save', 'crt save', 'flush image' for Final Expansion, Megacart, Ultimem, VIC Flash Plugin

The DOS - DOSBox Staging emulator has been updated.

Summary
- Pentium MMX emulation
- ESS Enhanced FM Audio
- numerous audio-related enhancements
- a large number of game compatibility fixes
- improved Windows 3.1x compatibility
- supercharged 3dfx Voodoo emulation performance
- experimental Windows ARM64 support

Game compatibility fixes
- Fix regression in Command & Conquer: Red Alert where the emulator crashed after playing the game for a while
- Fix regression in The Magic Candle 2: The Four and Forty where the second MIDI sequence did not play
- Fix regression in Soltys where the Gravis UltraSound was not starting up after the game auto-detected it
- Fix regression that prevented audio playing in HELL: A Cyberpunk Thriller on the Gravis Ultrasound
- Fix Dunkle Schatten 2 freezing after startup
- Fix distorted HUD issue in the 3dfx Voodoo version of Archimedean Dynasty
- Fix the odd horizontal black lines appearing in the following Synthetic Dimensions games:
 - Chronicles of the Sword
 - Druid: Daemons of the Mind
 - Perfect Assassin
- 1942: The Pacific Air War can now be played with sound when using the JEMM memory manager
- Generically fix all Windows 3.1x games that complain about enabling file sharing, asking the user to run SHARE.EXE. This fixes at least the following games:
 - Comix Zone
 - Garfield Caught in the Act
 - Microsoft Flight Simulator (v5.0, ATC Workshop)
 - Monopoly
 - Ultimate Yahtzee
- Fix the intro tune in Bumpy’s Arcade Fantasy using the wrong instruments on the MT-32
- Fix the AdLib intro jingle not playing in Silmarlis games (e.g., Crystals of Arborea, Ishar 1 & 2, Storm Master, Transantartica, etc.)
- Fix flipped Sound Blaster Pro 2 output filter behaviour in Doom and all games that toggle the filter programmatically

Graphics
- Remove the ‘openglnb’ output mode
- New xBR upscaler shaders
- 3dfx Voodoo improvements
 - 16-bit memory writes have been fixed in our Voodoo emulation; this resolves the distorted HUD issue in the 3dfx Voodoo version of Archimedean Dynasty
 - The voodoo_multithreading confing setting (which previously toggled three extra worker threads) has been replaced with voodoo_threads, which uses up to eight threads based on the number of available physical CPU cores. This is enabled by default (auto setting), but you can override it by setting the number of threads manually from 1 to 16
- The multithreading performance of the Voodoo emulation has been generally improved—at the cost of higher overall CPU usage. Set voodoo_threads to 3 or less to conserve battery power on a laptop
- Fixed a bug where the wrong shader could be picked when starting a Voodoo game with the adaptive CRT shaders enabled

Other graphics improvements
- Fixed the hardware cursor handling on the S3 Trio64 card; this fixes the display corruption on exit issue in the Teddybear’s Revenge demo by Eclipse
- Now we use linear 128 KB video memory pages for all VESA modes. Some games exploit this low-level detail of some SVGA cards to access the video memory as a single contiguous 128 KB memory block instead of manually flipping between two 64 KB pages. This enhancement gets rid of the odd horizontal black lines in the following Synthetic Dimensions games and possibly in other games and demoscene productions too that use the same hack:
 - Chronicles of the Sword
 - Druid — Daemons of the Mind
 - Perfect Assassin
- Fixed a regression where video captures resulted in slightly larger file sizes than previously 

Sound
- Multi-threaded audio processing
- ESS Enhanced FM Audio (ESFM) emulation
- Here’s a non-exhaustive list of games that support ESFM Enhanced FM music
 - 11th Hour, The
 - Advanced Civilization
 - Callahan’s Crosstime Saloon
