New in This Version

• 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.
