I have a switcher in a JAMMA game from 1987 that is not using this, but I hear that the older games do. Is this game not old enough to be using this? Also why do some switchers have OV on them and some have FG? What do these mean? You have to excuse my Noobness as I am having a switcher issue right now and am trying to learn more about them and how they work.
