Version 1.34

Version 1.34 changes:

• Improved MCGA compatibility.
  This involved intercepting every access to video memory, so some changes to the CPU emulation were required.
  However, this is a useful stepping stone on the way to VGA support.
  Microsoft Word 5.5 now works correctly in mode 11.
  

• Support for CGA palette modification via MCGA palette registers added.

• Various BIOS bug fixes

• Added implementation of the INS and OUTS instructions.
• Improved CGA emulation to support CRTC page offset in 320x200 graphics modes.
• Improved BIOS compatibility.
• Improved PIT 8253 support - added mode 0 support for timer 0.
• Implemented dummy port 0x0201 to make the system behave correctly for no joystick present.
• Fixed SDL debug break on interrupt entry point handling.
