0.83.13

• DOSBox-X can now resolve file paths in its config
  options that include environment variables on non-
  Windows platforms (e.g. ${HOME}..) as well. A new
  config option "resolve config path" (in [dosbox]
  section) is added to control path resolving in the
  config file (e.g. to resolve tildes only by setting
  to "tilde", or disable all path resolving). (Wengier)
• System menu text in Windows builds now match the text
  in the drop-down menus to be translatable by language
  files and is compatible with Unicode. (Wengier)
• The error "Access Denied" is returned instead of
  "File not found" for files opened exclusively in
  another program on mounted local drives. (Wengier)
• S386C928 hardware cursor fixed to divide X coordinate
  by bytes per pixel indicated in the control register
  to match apparent Windows 3.1/95 behavior. Cursor
  now tracks host properly even in highcolor/truecolor
  modes.
• Added support for the RetroWave OPL3 hardware player.
  Set "oplemu=retrowave_opl3" in [sblaster] section of
  the config file to use it. Config options including
  "retrowave_bus", "retrowave_spi_cs", "retrowave_port"
  are added to adjust its settings. (ClassicOldSong)
• Added support for S386C928 hardware cursor color
  selection in 256-color mode, which is different
  from later cards.
• S3 XGA "BYTE SWP" fixed only to byte swap if the
  transfer is 16-bit wide. This fixes the dither
  pattern drawn by Windows 95/98 when you select
  "Shutdown" from the Start menu.
• IMGMAKE command is now disabled in the secure mode,
  similar to commands like IMGMOUNT. (Wengier)
• Added config options "working directory option" and
  "working directory default" in [dosbox] section of
  the config file to provide various options for the
  users to control DOSBox-X's working directory. For
  example, DOSBox-X can use the primary config file
  directory or the DOSBox-X program directory as its
  working directory. You can view the DOSBox-X'safe
  working directory with CONFIG -L command. DOSBox-X
  is also able to save the working directory that a
  user selects to global config files. (Wengier)
• DOSBox-X will now also try to read the config file
  named dosbox-x.conf in the user config directory
  when searching for config files at start.
• Added new command-line options -promptfolder and
  -nopromptfolder which will cause the folder prompt
  dialogs to show or not to show at startup.
• Mac OS X builds will prompt the user to select a
  folder at startup if run from the Finder (or from
  the root directory). The folder selected will then
  become the current working directory of DOSBox-X.
  This makes it possible to start DOSBox-X with a
  config file of your choice and to control where
  the capture, save states and other files go.
• Fixed Tseng ET4000 640x480 256-color SVGA mode
  when using the ET4000.BIN VGA BIOS, or Windows 98.
• Added segment limit checks in Normal core for
  MOVSB/MOVSW/MOVSD and STOSB/STOSW/STOSD, which is
  needed for DOSBox-X to work with the Windows 3.1
  S3 86C928 display drivers that use segment limit
  exceptions to fake a linear framebuffer.
• Added S3 XGA "byte swap" emulation, needed for
  correct menu/titlebar display in Windows 3.1 when
  using the S3 86C928 driver.
• Added YUV (YUY2) overlay to S3 Trio64V+ card
  emulation. Tested with XingMPEG under Windows 3.1
  and ActiveMovie under Windows 98.
• Added machine types for 5 different variations of
  S3 chipset: Vision864, Vision868, Trio32, Trio64,
  and (experimental) Trio64V+, ViRGE, ViRGE/VX, and
  S3 86C928.
• Removed second PCI BAR for S3 MMIO register space.
  S3 datasheets do not show a second BAR. Windows 95
  is perfectly happy without it.
• S3 SVGA XGA emulation BlitRect now supports
  COLOR_CMP. DirectX-based Windows 95 games are now
  able to blit in 256-color mode with a transparent
  color key value.
• ANSI.SYS emulaion now supports the "Device Status
  Report" escape when asked through code 6 (report
  cursor position)
• Fixed RAM mapping bugs related to MDA/CGA/Hercules
  emulation and the "allow more than 640kb" option,
  that failed to map RAM as expected, and because of
  that, easily triggered a "corrupt MCB chain" error
  message.
• Worked around the mounting issue for disk or CD
  image files with LaunchBox, by allowing a mounting
  command-line with single quotes like IMGMOUNT D
  'X:\FILES\DOS.IMG' on Windows systems. (Wengier)
• Restored Pentium MMX emulation code for the dynamic
  x86 core to that of version 0.83.11 for better
  compatibility with some Windows 9x games. (Wengier)
• Added "compresssaveparts" config option (in the
  [dosbox] section) which when set to false will not
  compress the components in saved states. (Wengier)
• When the current reported DOS version is less than
  7.x and the user tries to mount a LBA or FAT32 disk
  image, DOSBox-X will now show a message to ask if
  the user wants it to set the required DOS version
  automatically and proceed. (Wengier)
• DOSBox-X will now show the folder mounted after
  mounting to a drive from the menu. (Wengier)
• Fixed MOUNT and IMGMOUNT commands unable to mount
  directories or image files that contain non-ASCII
  characters in the code page on Windows. (Wengier)
• Fixed CapsLock may not work properly in Windows
  SDL1 builds when -fs option is used. (Wengier)
• Fixed the cycle information on the title bar when
  the Turbo mode is enabled. (Wengier)
• Fixed that some games using the DOS4GW Extender
  may not work due to swap file issue. (Wengier)
• Fixed that the clipboard copy and paste may not
  work when the current code page is 808 or 872
  and you are using Windows. (Wengier)
• Fixed the handling of the "Save & Restart" button
  in Configuration Tool when using Direct3D output
  in Windows SDL2 builds. (Wengier)
• Fixed incorrect display issue when using TrueType
  font (TTF) output with customized screen dimension
  when fastbioslogo=true is set. (Wengier)
• Fixed CD audio not looping for individual tracks
  in games like Alien Trilogy. (kcgen)
• The command "MIXER /LISTMIDI" now lists the ROM
  directory/files and sound fonts for MT32, Synth
  and FluidSynth MIDI device when active. (Wengier)
• Debugger "DOS XMS" command will only list handles
  that are allocated, or with nonzero address or
  nonzero size, to avoid showing irrelevant
  information. (joncampbell123)
• Added LOADFIX -EMS option to allocate/free
  EMS (expanded memory). (joncampbell123)
• LOADFIX -D -XMS will free all XMS blocks
  allocated by LOADFIX -XMS. (joncampbell123)
• LOADFIX -A will not allocate memory unless there
  is memory below 64KB to fill. (joncampbell123)
• INT 15h PS/2 mouse functions now clear pending
  PS/2 mouse interrupt as part of the BIOS call.
  This should resolve unresponsive mouse issues
  with Windows 3.1. (joncampbell123)
• Add config option "mt32.model" in the [midi]
  section to force a MT-32 model to use. (Wengier)
• Updated the MUNT MT-32 library to the latest
  version 2.5.0. (Wengier)
• Updated FLAC decoder library to the latest version
  (0.12.29 by David Reid). (Wengier)
• Integrated SVN commits (Allofich)
  • r4436, r4437: Rewrite store integer instructions
    to check if the result fits.(vogons 78127)
  • r4447: Attribute Controller port alias on EGA
    machine. Fixes EGA display of older Super Pac-Man
    release.
