  Name:         UpdateFrame

  Description:  Updates the internal state by only one frame in the current mode.

  Arguments:    frame_count      Frame count for the current operation.

                player_count     Current number of players (number of valid input elements)
                own_player_id    This system's player number

  Returns:      Returns FALSE if the current mode ends this frame and TRUE otherwise.
