Checks During Game Start
• Game Start
Required A game must be started from a peripheral that is connected
Compliance Item to the 6Player’s port with the lowest port number out of the
valid ports.
This port must be a input peripheral connected to
Control Port 1 or a input peripheral connected to a 6Player
port with the lowest port number. The 6Player in this case is
connected to Control Port 1.
Recommended Note that in a multiplayer game, a game can be started by a
Compliance Item player other than player 1. This only applies when a 6Player
Tap is plugged into Port 1 of the Saturn.
• Detecting Active Ports
When a 6Player is used, there may be cases where active
ports must be chosen out of multiple valid ports. Detect the
active port as follows:
Required • From the valid port, assign player numbers in an
Compliance Item ascending order of port numbers to the active ports.
However, only the peripherals that have had their
START buttons pressed at a specific point in the
application are recognized (e.g., in the title screen).
Required Player numbers may be assigned to inactive ports using the
Compliance Item method above. Therefore, the user peripheral interface must
be designed so that the player number assignment is in
sequence with the port numbers. (For example, when a
START button is pressed during the game, a screen is shown
immediately that indicates which player joined the game at
that point.)
