This is normal. If you look under settings for that game, you will see just one player set of inputs. Most arcade games that are not multiplayer at the same time are like this. Your easiest option is mapping multiple controllers to the same inputs, and trusting them not to mess with you during your turn. Later, dabone This reply was modified 1 year ago by dabone.
