db6dac32c7 - PKE simulation almost finished. Needed enhancements: 
* trace file generation
  * FIFO pruning

- PKE functions still missing due to external dependencies:
  * interrupt to 5900 (igen?)
  * VU busy checking (sky-vu / coprocessor registers)
  * PATH3 masking (sky-gpuif / covert control interface)

43a6998b41 - PKE simulation code almost complete. Still missing: 
* handling of super duper packed UNPACK arguments
  * skipping of in-progress instruction on break/stop
  * interrupt generation to 5900
  * PATH2/PATH3 status checking & masking
  * ability to write to FIFO one word (instead of quadword) at a time
