Which games have lane change and how

Firepower introduced lane change. Firepower, Blackout, Scorpion, Alien Poker and Algar have a lane change switch on the right flipper only. Black Knight, Jungle Lord, Pharaoh and Solar Fire have none. Barracora, Cosmic Gunfight and Varkon use two matrix switches, one per flipper, moving the lamps left or right. Warlok has a single matrix switch fitted on both flippers, moving the lamps one way only.
