BTW, in games that you want 2-way action on, I wouldn't just restrict control to "left/right" or "up/down" because won't the control go to a dead zone if you hit a diagonal by mistake? You'd want Left = Left, or Up/Left, or Down/Left, and Right = Right, or Up/Right, or Down/Right in the Mame control set-up I think...
