Holding P1 start and P2 start are commonly used to skip quickly through the
games test mode, so I don't think this is a good idea (coming from a guy whose
had to go through test mode +1000 times and couldn't live without this
feature...). I vote for reset (or can't this be done?)

Totally agree; it's a pain to switch these wires when I play Star Trek on my
enhanced Tac/Scan control panel.

Optional right? (So you can use an encoder wheel if you have one)
