• television window shows CPU Cycle information for the scanline, in addition to Clock (issue #55)
• ports window includes Latch and Grounded toggle (issue #56)
• added SCREENSHOT command
  • screenshotting has been available for a long time when in playmode
  • this command gives the ability to screenshot from the debugger
  • command is also usable from HEADLESS mode

• ARM

• corrected behaviour of MAM (ARM7TDMI)
  • the size of the MAM latch was too large in previous version
  • the real size is 128 bits (or 4 instructions). I had set it to 128 bytes (32 instructions)
  • the practical effect is that timing constraints should now be more like real hardware

  • including when the peripheral port is left empty (issue #56)
