This is simply a list of things I need to figure out.

  • The precise timing of a video frame.
  • The number of cycles each value of PRC_CNT takes
  • Which\if timers sleep while the system is suspended
  • Check to see which IRQs are masked by the IRQ Enable and IRQ Branch flags
  • Determine the approximate amount of time sprite draw, map draw, and frame copy take (maybe min \ max \ avg)
  • Determine when the PRC stages fire (relative to PRC_CNT)
  • Check undocument Minx instruction behavior Done
