I'd recommend moving your emulation/admin controls off of the CP.
In my case, I've got some extra space between my CP and the end of the UAII cab, so I'm bumping my CP back and adding a keylock cover over admin functions.
Long story short:
I keep my ESC and Pause keys on the CP and move coin1, coin2, tab, reset, cpu power, etc. all under that little keylock space.
Also in my case, it means that Daddy, who is also the keyholder, can play the game with his friends for free, yet any kids that come around have to be very, very good to me in order to get some of the delicious tokens that magically provide credits.
Just some thoughts.
