This is simply a list of things I need to figure out.
- The precise timing of a video frame. <- Hmm, how precise?
-
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 behaviorDone
.. to be continued ..
