The Commodore Amiga console emulator has been updated - WinUAE

Custom chipset rewrite
- Custom chipset emulation (Agnus/Alice and Denise/Lisa) almost completely rewritten. Almost every part of chipset emulation is now internally cycle accurate
- Custom chipset Denise/Lisa emulation is now running in separate thread for large performance increase in accurate emulation modes compared to previous versions
- VPOSW/VHPOSW tricks are now cycle-accurately emulated without restrictions
- Horizontal and vertical blanking and sync start/end, csync, csync equalization pulses, etc are now fully cycle-accurately emulated, both hardwired and programmed. Mixing of hardwired and programmed is fully supported. Agnus/Alice hardwired PAL/NTSC sync generator is almost logic gate level emulated
- “Display” and Agnus/Alice vertical and horizontal counters are now fully separately emulated, display emulation now works correctly even if Agnus vertical or horizontal is moved backwards or forwards or anywhere (even outside of normal display range), unlimited times per line and/or field
- All screenmodes (including “Fake” NTSC or similar mode) now count total number of “display” lines and uses it to setup display height. These modes now work even if they do multiple V(H)POSW modifications
- Interlace detection now uses vsync timing like real displays
- BPLCON0 ERSY=1 without connected genlock sync stop timing is now accurate. This was faked previously
- Full AGA hires/shres bitplane and sprite horizontal granularity support. Separate subpixel mode does not exist anymore
- ECS Agnus/AGA UHRES bitplane and sprite RGA DMA slots (0x78, 0x7a) emulated. Completely useless feature because UHRES can only do some DMA transfers to nowhere. It needs extra hardware that was never implemented. UHRES needs to be emulated because (possibly accidentally enabled) UHRES DMA can steal cycles from copper, blitter and CPU
- NTSC LOL (long line) state is accurately emulated. Mismatched STRLONG strobe and LOL state now causes correct lores pixel wide horizontal shift. (Mismatched = for example CPU writing to STRLONG when line is not long)
- Blitter channel sequencer should be 100% accurate now, except possibly line to non-line mid operation switch. Blitter “micro-operation” timings are not yet 100%: when exactly it applies A shift, B shift etc. This will be tested and implemented in the future. Only affects blitter result if BLTxDAT/shifts/etc are modified mid-blit. Channel enable/fill mode/desc/minterm/BLTxMOD/BLTxPT mid-blit changes should be already fully accurate
- Collision emulation is now very fast. Collision mode default changed to Full collision
- Ultra extreme debug mode now shows normally hidden bitplane and sprite pixels inside horizontal and vertical blanking periods. Previously only background color was fully visible
- DMA debugger has much more detailed information available

Other new features
- Low level keyboard emulation. Emulates keyboard microcontroller internal ROM code and keyboard matrix, optionally with or without NKRO. All 3 keyboard MCU variants supported. (CSG 6570-036, 68HC05C and D8039HLC. 6500-1 used in A1000 keyboards is same as 6570-036 but with older ROM code. 6500-1 ROM is not yet dumped). Caps lock led state is fully emulated in low level keyboard emulation modes, including demos that flash caps lock led. Chipset panel “Keyboard connected” checkbox replaced with Keyboard mode (“Disconnected”, “UAE high level keyboard” and list of different low level emulated keyboard models)
- PCI Matrox Millennium, Millennium II, Mystique and Mystique 220 emulation from 86box (originally from PCem)
- Merged Voodoo 3 emulation updates from 86box
- Added 512kWOM A1000 512k WOM expansion emulation. Option in Expansions->Built-in expansions
- Added RIPPLE IDE controller emulation

Fixes
- Prometheus FireStorm PCI bridge PCI IO mapping fixed
- Fixed Mediator 1200TX second PCI window mapping logic
- Fixed TekMagic onboard RAM config type
- Do not reject (reject = not hardware accelerated, lets Picasso96 software fallback to handle it) uaegfx Picasso96 blit operation if RenderInfo BytesPerRow field is zero. Zero BPR is allowed
- GDI mode didn’t free all resources when switching between native and RTG mode
- If selected graphics API is not supported, test all other options. Previously failing D3D9 switched to GDI, even if D3D11 was available
- Fast/non-accurate emulation mode and writing to CIA high timer register didn’t load timer from latch immediately in oneshot mode if timer was already running (Introduced in 4.9.x)
- uaegfx RTG vertical blank interrupt might have been duplicated or lost in some situations (very old bug), depending on RTG panel refresh rate setting
- Passthrough printing mode fix for v4+ Windows printer drivers
- Fixed FDI disk image support
- JIT FPU mode FPU registers lost some accuracy when FPU registers were read/written to/from memory with FMOVEM
- Removing last sound device on the fly (for example USB sound card without enabled on-board sound device) crashed in WASAPI mode
- Added A1000 EHB Denise and non-EHB Denise models to Chipset panel. Also renamed existing entries
- Fixed strange window movement when clicking on title bar and keeping it pressed and “Automatically capture mouse when window is activated” was enabled
- Expansion panel SCSI controller ID selection enable/disable/selection fixed. (For example A4091)

Updates
- Default configuration is now cycle-exact A500. Previously default was approximate A500
- Query PC drive/network drive/removable drive status only after confirming drive type first. For example if “Add PC drives at startup” or “CDFS automount” is only ticked, don’t query status of possible network drives that might not be mapped or available, causing boot delays
- CD32 CD reads should be more real optical drive friendly, when CD32 is reading data sequentially (playing CD streaming animation or video), host side CD sector reads are now also sequential, without periodically re-reading part of previously read sectors
- Disabled annoying CD audio playback aOSD led flicker
- When exiting debugger, restore focus back to previously active window
- If real HD/memory card has Windows supported partition table and partition metadata can be queried without administrator privileges but administrator privileges are needed to read/write partition data, list partition(s) in Add Harddrive dialog with “ACCESS DENIED” text. Previously partition(s) were not listed
- Added Amiga GPT partition type support. Works the same as 0x76 partition type with MBR partitioned drives
- Add harddrive Lock option didn’t lock all partitions if drive had MBR partition table + one or more Windows supported partition types
- GUI Configurations file list’s expanded tree nodes are now stored in registry/ini and are loaded and expanded automatically in following sessions
- Hide expansion device “autoboot disabled” checkbox when device does not have any autoboot jumpers. (or have nothing to do with storage devices)
- Integer scale horizontal/vertical resolution aspect ratio correction should now work more sanely (for example if superhires + vertical doubling, output will be always vertically doubled first, after doubling, integer scaling ratio is selected). Supports also programmed doublescan modes
- TV Overscan options now work when combined with most filter modes
- Added (config file only currently, “rtg_noautomodes=true”) option that disables uaegfx automatically generated screen modes. With Picasso96 v3.4+ and P96Prefs new modes can be created manually, just like when using real hardware. Note: Older Picasso96 versions and PicassoMode utility don’t support manual uaegfx modes
- Added 3840×1080 to known uaegfx automatically generated resolution list (“known” = gets static mode id)
- Fixed crash when doubleclicking config tree view root node
- Subpixel emulation option removed. Emulation is now always subpixel accurate in accurate emulation modes
- On the fly chipset type switching improved (For example AGA colors are now preserved, not all registers were preserved fully previously)
- Added line count and type to bottom border status line (for example 313p or 625i), fully supports all weird modes
- Obsolete 16-bit host color depth support removed
- All software filters removed. Removal of 16-bit host screen depth support and always-enabled temporary graphics buffer (new chipset emulation does not need it anymore) makes software filter support unnecessarily complex and they are obsolete anyway. In the future better shader filter support will be implemented
- Serial port TCP/IP mode uses now TCP_NODELAY flag to reduce latency
- If selected WASAPI sound channel mode is not supported, try all possible channel modes until supported mode is found, or until all combinations have been tested. Also if channel count needs changing from stereo to higher channel count (for example sound device only supports 6 or 8 CH modes internally), use 6/8 channel cloned stereo variant because user might only have stereo speakers
- Limit initial Windows to Amiga clipboard copy to max 30k (initial = when Amiga is booted and Windows clipboard is not empty) if clipboard sharing is enabled. This prevent slow startup if clipboard sharing is enabled and configuration is not fast and Windows clipboard has some random large image
- Added address and length to sample ripper file names

The x86 emulator has been updated - MartyPC.

This update brings a massive list of new features, so here's a quick summary:
 - New sound system and sound devices including Adlib, Disney Sound Source, and SN76489 3-voice sound
 - New floppy disk image library enabling a ton of new floppy disk image types and support for several copy protections
 - New frontend supporting both native and WASM, support for native file dialogs
 - ATA device emulation, supported by XT-IDE and jr-IDE devices for larger hard disk support
 - VGA support and improved PCjr and TGA video emulation
 - Memory and register editing

New eframe Frontend
- Some dependency API changes prompted me to switch window frameworks. The active Desktop frontend for MartyPC is now based on a customized fork of eframe

Native File Dialogs
- The RFD crate provides access to native file dialogs for your particular OS, including File Open and Save dialogs
- Startup errors are now reported via a system MessageBox. You should no longer have to rely on the command line output to tell why MartyPC didn't start

New Devices
- VGA
 - The IBM VGA card is emulated at last. MartyPC's VGA is based off its EGA implementation, with appropriate changes and additions. Clocked up to 28Mhz, the VGA is an expensive device to run at a character-clock accurate rate, so you may need a fast computer. Mode 13h and ModeX/Y are supported (Wolfenstein 3D's 'ModeY' works!)
 - The Video Card debugger window will show you the VGA's register state, including the current palette in realtime
 
- XTIDE Hard Disk Controller
 - An XTIDE Rev 2 device can now be emulated. Since this BIOS is open-source, a machine configuration that includes hard drive support is now the default: ibm5160_xtide
 - If you want the 'authentic retro' experience, the IBM/Xebec controller is still available as ibm5160_hdd as usual
 - The VHD creator has been updated to support the wide selection of common hard drive geometries that the XTIDE can support. You'll need to be running a machine with the XTIDE configured to see them
 - It is now possible to take a VHD file from 86Box (assuming you created it as a 'fixed' VHD) and use it in MartyPC (and vice versa!)
 
- jr-IDE Hard Disk Controller
 - To go along with the XTIDE, you can now emulate the jr-IDE. This gives you LBA-enabled ATA hard disk support and 736k of conventional memory backfill for your PCjr
 
- Adlib Music Card
 - The first audio device in MartyPC besides the PC speaker is the Adlib Music Card. OPL2 emulation is provided by the highly-accurate nuked-opl3 library
 
- SN76489
 - The 3-voice sound chip found in the IBM PCjr and Tandy 1000 will be automatically installed on these machines
 
- Disney Sound Source
 - If you have a parallel adapter specified, you can attach a Disney Sound Source, and enjoy various squawky digitized sounds in games that support it (Mostly Disney titles, Wolf 3d, Prince of Persia, and a few others. See Mobygames for a list of supported titles)
 
- Memory Expansion Cards
 - Conventional memory expansion cards can now be specified, at any address and with any capacity. It is possible to have non-contiguous memory regions if you decide to do so, but caveat emptor
 - An overlay for the IBM PCjr called 'pcjr_memory_sidecar' will provide an extra 512k to bring your PCjr up to 640k
 
Bitstream-level Disk Image Emulation
 The inclusion of the fluxfox disk image library has greatly expanded MartyPC's floppy disk image support, and enabled support for several copy protection schemes.
 
- Disk Image Support
Fluxfox supports reading a wide array of disk image formats:
 - TD0 (TeleDisk)
 - IMD (ImageDisk)
 - PSI (PCE Sector Image)
 - TC (TransCopy Image)
 - PRI (PCE Bitstream Image)
 - MFM (HxC/MFM Bitstream Image)
 - HFE (v1) (HxC Bitstream Image)
 - 86f (86Box Disk Image)
 - MFI (Mame Floppy Image)
 - SCP (SuperCardPro Image)
 - RAW (Kryoflux stream file set)
 
Disk image loading is multithreaded so large disk images can be loaded without pausing the emulator.

- Bitstream Image Writing
 Fluxfox can write bitstream images to 86f and PRI formats.
 
- Disk Image Visualization
 fluxfox also enables a new Floppy Image info window, including a Disk View that shows a graphical visualization of the disk surface.

- Zip Floppy Mounting
 - Thanks to rust-fatfs, we can now dynamically build FAT12 images. This enables mounting ZIP archives as floppy images. Of course the contents must fit! By default, an image of the largest supported size for the applicable drive will be created. There are a few options as well to enable creation of bootable diskettes
  - See the Wiki for more information
  
Memory Visualizer
- Using the new Memory Visualizer window, you can now view the contents of memory graphically, interpreting raw bytes as rendered text mode, or 1,2,4 or 8bpp pixels. This is a good way to explore the contents of memory, and when investigating a running game one can find things like the game's back buffer as well as sprites loaded into memory

New Debugger Features
- A floppy controller debug window shows operational state and command logs
- A debug window for the SN76489 shows channel state with optional UV meters and oscilloscope displays
- The memory viewer will now resolve memory-mapped addresses, although what is shown in those regions is device-specific
- The memory viewer now supports memory editing
- The CPU state viewer now supports editing registers and flags when the CPU is paused
- The Disassembly viewer will now disassemble instructions in memory-mapped regions, such as PCjr cartridges
- Display interrupt numbers as hex in the IVT viewer
- Show both source and return address in the Call Stack

Frontend Bug Fixes / Improvements
- Mouse capture is even easier, with double-click to capture and middle-click to release implemented by default

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

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

 - Heaven’s Dawn
 - Heroes of Might and Magic II
 - Magic Carpet 2
 - Settlers II, The
 - Shannara
 - Theme Hospital
 - WarCraft II

The Atari 2600 emulator is written in Go

Bug Fixes
- Rewinding of ELF binaries caused visual artefacts on screen
- Changes to screen rendering prevented the VideoChess bot from starting
 - Bug introduced in v0.31.0
- Added ELF to list of valid ROM extensions
 - A file with the .elf extension would not be shown by the ROM selector
- Mouse wheel events could crash the emulator
 - This affected MacOS builds on machines where mouse-wheel style scrolling is done with a touch-pad
- Replay button in tracker window could crash the emulator 

Changes
- TIA audio sampled every colour clock
 - This fixes problems with ROMs where the channel volume is update more than twice per scanline
- Added option to enable warning for "undefined symbols" when loading ELF ROMs
 - It is possible to compile an ELF binary with undefined symbols. Rather than reject the file when it is loaded, I have chosen to allow the ROM to execute and to continue until the symbol is referenced (which may never happen)
 - It is possible to compile an ELF binary with undefined symbols. Rather than reject the file when it is loaded, I have chosen to allow the ROM to execute and to continue until the symbol is referenced (which may never happen)
- Added CARTRIDGE SETBANK command
 - It wasn't possible previously to set the current bank of a cartridge. I had originally chosen to avoid the problem because of the high variety of ways a mapper might implement banking (if at all)
 - The options to the SETBANK command vary depending on the specific mapper but generally, a mapper will expect a numeric value
  - Segmented mappers can take multiple numeric values. Separate values with a colon
  - In some instances, segments can be mapped to cartridge RAM. add an 'R' after the segment number to indicate the use of RAM. For example, the 3e mapper allows very flexible mapping of RAM
     CARTRIDGE SETBANK 1R:2
  - Some segmented mappers only allow a predefined 'pattern' of segments. In these cases the numeric value to the SETBANK command will be a pattern number. The two mappers affected by this are Supercharger and Wickstead Design
  
Other Changes
- Added ELF support for REL32 and PREL31 relocation
- Improved DWARF support for typedefs
- Better decision making over whether variables are in global scope
- Prevent possibility of infinite recursion in DWARF builder
