Which sound board each game uses
World Cup through Pokerino share the first sound board (sounds only on scoring). Flash through Algar share a board with continuous background sound. Gorgar to the end of System 7 use a board with a speech board connector; Gorgar, Firepower, Blackout, Alien Poker, Black Knight (later units), Jungle Lord and Pharaoh add a speech board, while Solar Fire and later have no speech and no speech connector. Sound ROMs are game-specific.
