Some games like forgotten worlds and GnG don't have free play. My solution was just to run a coin up button in my cab with 4x CPS1 boards with a jamma switcher, which sounds like what i'll have to do with the multi.All OFF is what works better. You can try to then activate the FREE PLAY for one game and see. I can't remember if FREE PLAY was the same dip for all games.
