Smash TV, Total Carnage, Robotron, and a handful of others used two sticks. The controls for player one will be labeled as LEFT/UP, LEFT/DOWN, LEFT/LEFT, LEFT/RIGHT, RIGHT/UP, RIGHT/DOWN, RIGHT/LEFT, and RIGHT/RIGHT. The first part of each of these directions indicates the stick to be used. LEFT/UP means LEFT stick (player 1 side), direction UP. Make sense?
