A thought just occurred to me.
When I was putting the Pokey code into Pac-Man 320 / Ms. Pac-Man 320, there was a bug which occurred when the Pokey was not activated; The 'Random' address would always return the same number.
Could this be a quick / easy way to check for the existence of a Pokey at a specific address? I.E. read the Random address, say 5 times, and if the same value comes out all 5 times Pokey is not there.
Is this reliable?
