• Allow more than 640KB of conventional memory,
  regardless of "allow more than 640kb" option, for
  Tandy machine type. The setting is capped to 768KB
  to reflect Tandy systems with that upgrade, which
  is said to allow a full 640KB for DOS and 128KB for
  video RAM without any conflict from the MCB chain.
  Adjust Tandy video emulation for 768KB case. This
  fixes "Might and Magic III Isles of Terra" crashes
  in Tandy mode and Tandy graphics because the game
  does not correctly handle the memory configuration
  when less RAM is involved. (joncampbell123).
• Fix code page CPI/CPX loader to allocate 128KB of
  memory instead of 84KB. The code allocates a 64KB
  stack for the executable code within. The 84KB
  allocation permitted the initial stack pointer to
  exist beyond available conventional memory if
  conventional memory size was below about 156KB and
  cause a crash. This is a quick fix, a long term fix
  would be to instead set the initial stack pointer
  to some offset below 0xFFFE based on available memory,
  just as the .COM executable loader was modified to do
  some time back to enable proper execution when
  memsize < 64KB. (joncampbell123)
• Do not load country/font information at startup
  if the code page to load is the same as the default
  code page. (joncampbell123)
• Fix Tab/Shift+Tab in Configuration GUI regarding
  setting text fields that have a ... button to select
  from an enumeration. Those buttons are no longer a
  trap for tab enumeration. (joncampbell123)
• Fix Mac OS SDL1 keyboard support code to properly
  fill in unicode character values in relation to
  IME checks. This fixes a problem where it was
  impossible to type anything in the configuration GUI
  in SDL1 Mac OS builds. (joncampbell123)
• Mark VBE mode 0x212 as "do not list" so that it does
  not appear in normal VBE mode enumeration, while
  keeping it valid for the Windows 3.1 driver which
  assumes the mode is there at that number without
  enumeration. By not listing the mode, drivers like
  VBEMP and DOS application code will not attempt to
  use it. There is already another mode number for
  640x480 24bpp anyway. (joncampbell123)
• Fix VBE mode 0x212, which is 640x480 24bpp packed
  mode but with a per scanline stride of 2048 bytes
  per pixel set aside for the Windows 3.1 driver and
  the "640x480 (1Meg) 16 million colors" setting,
  so that the VBE "Get Mode Info" call reflects the
  proper per-scanline stride instead of the ideal one.
  This should fix complaints about VBEMP and 640x480
  24-bit color mode. Given how minimal the use of the
  mode is by the Windows 3.1 driver, the 2048 byte
  mode does not permit setting scan line length or
  display start i.e. panning is not permitted.
  (joncampbell123).
• Fix Pentium Pro emulation to support microcode
  related MSRs so that Windows 98 does not crash
  on startup when cputype=ppro_slow. (joncampbell123).
• Added SMV debugger command. This is the linear
  (virtual) equivalent of the SM "Set Memory"
  command. (joncampbell123).
  (#3826)
• Fix debugger help command to list both C / D commands
  and the DV/DP commands. (joncampbell123)
• Add VGA FONTDUMP debugger command for those
  who might want to take custom fonts in text
  mode and do something with them outside the
  emulator. "VGA FONTDUMP" followed by a filename
  which must have the extension .BIN (for a raw
  64KB dump of font RAM) or .BMP (for a formatted
  dump as a monochrome bitmap file). (joncampbell123).
• Disabled code to randomly return GDC drawing
  status active. The implementation was causing
  severe performance issues. The code has not
  been removed because it could be optimized and
  fixed and could even follow the state of GDC
  drawing. (joncampbell123)
• VGA 6-bit DAC mode expand to full 8-bit range,
  instead of simple shifting (joncampbell123).
• Fix 8254 PIT emulation (joncampbell123)
• Add dosbox.conf option "cpuid string" to allow
  CPUID to return custom ID strings instead of just
  "GenuineIntel". Have fun! (joncampbell123)
• Fixed build to properly compile against internal
  SDL/SDL2 library even if an external version is
  available (joncampbell123)
• Fixed some violations of the one definition rule.

  (maron2000)
• Adjust Int 11 return value to better match real
  BIOSes. (Allofich)
• Limit the "always return bit 6 of port 61h as set

    cleanup.
  • r4481: Push registers for most DOS function calls;
    prevents a bug in UNLZEXE from causing a crash, and
