Chrono Trigger: Multiplayer

This hack enables local cooperative play for up to 3 players to enjoy with family and friends.

This does not necessarily mean that a group of 3 people is required to play. If only controller 1 is connected, it fully controls the game. If there are more controllers connected, these will control the character corresponding to the slot in combat. If a player wants to withdraw, simply disconnect their controller and control of their character will transfer to controller 1.
