sequences.
Checks During Game Start
• Game Start
Required Always use player 1 controls (the compatible peripheral
Compliance Item connected to Control Port 1) to start a game .
Recommended During a game, player 1 controls should be used for
Compliance Item mode/option setting purposes.
Required In multiplayer games where players can have different

other than that of player 1.
In a multiplayer game, all players should be allowed to
set up their own user options and modes independently.
• Detecting Active Ports

Compliance Item start (e.g., prompt the player to press the START button to
activate the peripheral).

Item selected for a game is equal to the maximum number of
players supported by the game.
Checks During the Main Game
• Peripheral (Dis)connect Check
Required When a peripheral is disconnected (or connected) during the
Compliance Item main title loop game sequence for any reason, make sure
that the application can support those operations without
any problems.
• When a Peripheral is Disconnected
Required If an active peripheral is disconnected during the course of
Compliance Item an action or time-oriented game, detect the disconnect as a
“null input” state, followed by a system pause or a warning
display. In either case, the game must not continue while the
peripheral is disconnected. The affected port becomes an
unused active port.
