- Note that the alternate "Potentiometer" controls (which set 2 has as the default) must first be calibrated by holding 1P Button 2 + Start on the "I/O Check" screen.

- The alternate "Optical Sensor" controls are not currently emulated.
-
- there may still be some problems with the 156 co-processor, but it seems to be mostly correct
