Firmware Diagnostics
The adapter always performs a few simple diagnostic checks at power up and if any
problems are detected it will print the result to the console’s screen.
If the console is reset (or switched on) with the joypad START button held down
then the adapter firmware will print to the screen to report on it's current
configuration and the results of some more extensive self-tests.
