I posted a week or so back with the whole list of problems this game was giving me. After going over the schematics and the manuel for space mission I fixed most of them, except one. I cant get the thing to grant me a dang extra ball. Can activate it. Same player shoots again. Extra ball relay energized, but then ball drains, light goes off, moves on to next ball. Been trying different things for three days, connecting some switches on the bonus unit manually will grant it. But cant figure it out for the life of me.
