DOSBox-X 0.83.12 (2021-04-01)

 DOS模擬器 DOSBox-X 發布新版，更新如下 :

• Tandy graphics emulation fixed to accept 8 bits
  for vertical total and vertical display CRTC
  registers, which is needed for the tweaked
  graphics mode used by Math Rabbit to display
  correctly.
• INT 10h will no longer fill in three fields in
  the BIOS data area (video CTL, char height, and
  video switches) unless the machine type is
  EGA or VGA. Those fields do not exist otherwise.
  Certain games like Mindscape's "Road Runner" game
  require those fields to be zero as part of it's
  Tandy detection routine.
• PCjr mode will omit the reserved graphics RAM
  MCB block, and will subtract 16KB from the top
  at the BIOS level, if emulating 128KB system
  memory or less.
• You can now run PCjr mode with as little as
  128KB of RAM. Removed 256KB minimum check from
  DOS kernel. Certain games (Mickey's Space
  Adventure) require memsizekb=128 and memsize=0
  in PCjr mode or else it will not work correctly
  due to how the game locates video system memory.
• Fixed Tandy mode to place video memory at the
  top of conventional memory and allow running
  Tandy mode with a memsizekb setting as low as
  64KB, though 256KB or higher is recommended.
• Added Tandy "real memory size" field in the
  BIOS data area.
• Tandy emulation updated to subtract 16KB from
  top of conventional memory, which fixes some
  games and follows DOSBox SVN behavior and real
  hardware according to others on the Vogons forums.
• Fixed bug that limited Tandy mode to 624KB of
  conventional memory. 32KB of video RAM is taken
  from top of memory, losing half of the 32KB
  breaks games that write to the system RAM instead
  of B800:0000 segment and causes half the graphics
  to not render.
• CD-ROM image emulation now supports ISO images
  that are 2GB or larger, 32-bit integer size limit
  has been lifted.
• Increased upper limit of "prebuffer" config option
  (in [mixer] section) from 100 to 250. It is still
  recommended to set a value less than 100. (Wengier)
• Added scrollbar buttons to the Configuration Tool,
  so that the scrollbars better resemble the style of
  the Windows 3.1 scrollbars.
• The help window for the Configuration Tool will now
  display possible and default values for the config
  options in addition to the descriptions. (Wengier)
• Updated the MMX patch code by kekko. (Wengier)
• MIXER command now supports the /GUI option to show
  a popup window to display the mixer information.
  Also improved its /LISTMIDI option which will show
  the name of the current MIDI handler and you can
  optionally specify a MIDI handler name (win32/alsa)
  to show the information for this handler. (Wengier)
• Improved the compatibility of AUTOTYPE command with
  games like Asterix & Obelix. (Wengier)
• The config options ttf.wpbg, ttf.bold, ttf.italic,
  ttf.underline, ttf.strikeout, and ttf.char512 can
  now be modified dynamically with CONFIG -SET ...
  commands, e.g. CONFIG -SET ttf.wpbg=2. (Wengier)
• The minimal value for the ttf.ptsize config option
  has been decreased from 10 to 9. (Wengier)
• Added menu item "Save logging as..." (under "Help"
  -> "Debugging options") to save the current logging
  content to the specified file. (Wengier)
• Added slirp backend support for the NE2000 network
  feature (in addition to the existing pcap backend).
  There are config sections named [ethernet, slirp]
  and [ethernet, pcap] now to set the options for the
  slirp and pcap backends respectively. Please refer
  to the networking guide in the DOSBox-X Wiki for
  more information about the backends. (Jookia)
• FAT driver can now support PC-98 HDI images with
  partitions that start at any physical sector even
  if the start is not a multiple of the ratio of
  logical to physical sector size. This allows the
  HDI image of Dragon Knight 4 to mount.
• Control character 7 (BEEP) is now allowed while
  executing batch files without warnings. (Wengier)
• With the setting "core=auto" DOSBox-X now updates
  the menu in the "CPU core" menu group automatically
  between "Normal core" and "Dynamic core" to reflect
  the CPU core which is currently in use. (Wengier)
• Fixed Windows 95/98 installation failures caused by
  FAT driver and DOS API changes in previous version.
• Fixed well-intended but erroneous fall through case
  in the INT15 handler that prevented 3rd party mouse
  drivers from detecting the PS/2 mouse.
• Fixed the color issue with the Configuration Tool
  in the macOS SDL1 build. (ant_222)
• Fixed switching ttf.cols, ttf.lins, and ttf.font
  options dynamically in full-screen mode. (Wengier)
• Fixed menu options "Increase TTF font size" and
  "Decrease TTF font size" (both under "Video" =>
  "TTF options") not working (but keyboard shortcuts
  and those in the system menu work). (Wengier)
• Fixed setting option "ttf.wp=xy3" or "ttf.wp=xy4"
  not working (but "ttf.wp=xy" did work). (Wengier)
• Fixed preview function in WordStar not working for
  TrueType font output in previous version. (Wengier)
• Fixed the issue that caused Windows 3.x group file
  corruption on hard disk image files. (SnikoLoft)
• Integrated SVN commits (Allofich)
  • r4416: Added ability to start and stop avi
    recording, and to start keymapper, from config.
  • r4405: Smarter clearing of the dynrec cache.
