So JMK , that gate in your Spidey is just a one-way gate correct ? ( ie. the ball can come up through from the bottom , but coming from the top it always goes to the shooter lane ) . If I am thinking correctly from the adjustments in the menus listed by the OP then the original design would've called for a solenoid controlled gate so it can stay shut ( send the ball to shooter lane ) or open ( back to playfield ) .
Still a cool feature nonetheless .
