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
 - Gene Machine, The
 - Heaven’s Dawn
 - Heroes of Might and Magic II

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
