in addition to the "standard" keys (typically "1" to start game and "5" for coin), I've added "3" as another coin input and "4" for coin and auto-start game (like I recall the dime slots generally were) to simulate 3 coin slots
when game is not in progress, holding down left flipper for about 3-5 seconds will bring up the options menu. left flipper selects item, right flipper changes option.
I've also included shadows for the ball and flippers. If you want to turn them off look for these lines at the beginning of the script:
Const ShadowFlippersOn = true
Const ShadowBallOn = true
change to false if you want either of the shadows not showing on your tables
