I figured it was finally time for a new build, so here’s what’s new:

• Switched to .NET framework 4
  
• Implemented x86 protected mode task switching support (Quake, CWSDPMI, C&C)
  
• Fixed bug with 80-bit operand floating point instruction decoding (XCOM)
  
• Added a few missing floating point instructions
  
• Tweaked DOS emulation to get programs compiled with DJGPP working (Quake)
  
• PIC now allows its base interrupt vector to be reprogrammed
  
• Rewrote address decoder to improve emulation performance
  
• Finally fixed issue preventing Borland’s RTM extender from working (Jazz Jackrabbit)
  
• Improved Sound Blaster DSP audio, should hopefully eliminate most of the playback glitches
  
• VGA LineCompare register is now properly emulated (Jazz Jackrabbit, Incredible Machine 2)
  
• Implemented instruction tracing for CPU trap flag (Second Reality – at least the menu loads now)
  
• Fixed bug in DOS EXE loader where maximum memory field was not respected
  
• Added support for ADPCM compressed playback on Sound Blaster (Traffic Department 2192)

This is pretty much a compatibility and performance update with no new application features. There’s still a lot of open issues I’m looking into, but this should be faster and more stable than 0.60.
