Abstract: A game system is provided in which a plurality of pairs, each consisting of: a first input device provided with a first operation section; and a second input device provided with a second operation section, are wirelessly connected to a game apparatus, and in which a game process is executed based on operation data obtained from the first input device and the second input device. As an example, each of the first input device and the second input device includes a display section, wireless communication means for performing communication for the operation data and information regarding each pair, and a display control section for controlling a display form of the display section. The display control section controls the display form of the display section so as to be a display form corresponding to each pair. The game apparatus executes the game process based on the operation data for each pair.

Abstract: A second game controller includes both of a first detection section provided in a first game controller, and a second detection section provided in an extended controller that is detachably connected to the first game controller. An operation to the second game controller is detectable by the both detection sections, but the result of the detection by the first detection section is not included in transmission data to be transmitted to a game apparatus.

Abstract: A first game controller that can be used by both a first game apparatus and a second game apparatus transmits its operation data by using a data format having a first data region including a header, a second data region including key data, and a third data region including data of an extended controller. A second game controller that can be used by the first game apparatus also uses a data format having similar three data regions, but the second data region is merely secured as a region, while all operation information is included in the third data region and transmitted.
