Information processing system, information processing device, controller device and accessory

A game system comprising:

• a main unit;
• at least one processor;
• and
• a first controller configured for removable attachment to the main unit, wherein
• the first controller is configured to communicate with the main unit via wireless communication when the first controller is detached from the main unit,
• one or more of the at least one processor is configured to process inputs to the first controller for controlling a game, and
• one or more of the at least one processor is configured to process a first input to the first controller according to a first interpretation to produce a first in-game effect when the first controller is attached to the main unit and to process a second input to the first controller, different from the first input, according to a second interpretation different from the first interpretation to produce a same first in-game effect when the first controller is detached from the main unit.

A game system comprising:

• a main unit;
• at least one processor;
• and
• a first controller configured for removable attachment to the main unit and including a directional input device, wherein
• the first controller is configured to communicate with the main unit via wireless communication when the first controller is detached from the main unit,
• the first controller is usable in a single style when the first controller is attached to the main unit such that a certain input direction of an input to the directional input device is directed in a predetermined direction relative to the main unit,
• the first controller is usable in a plurality of different styles when the first controller is detached from the main unit including a first style in which the first controller is oriented so that the certain input direction is a first direction and a second style in which the first controller is oriented so that the certain input direction is a second direction different from the first direction, and
• one or more of the at least one processor is configured to identify use of the first controller in the first style and use of the first controller in the second style and process inputs to the directional input device according to the identified style.

A game system comprising:

• a main unit;
• at least one processor;
• and
• a controller configured for removable attachment to the main unit and including a directional input device, wherein
• the controller is configured to communicate with the main unit via wireless communication when the first controller is detached from the main unit,
• one or more of the at least one processor is configured to process inputs to the controller for controlling a game, and
• one or more of the at least one processor is configured to process an input to the directional input device in a direction corresponding to a first dimension of the controller as an input indicating a first direction when the controller is attached to the main unit, and to process the input to the directional input device in the direction corresponding to the first dimension of the controller as an input indicating a second direction perpendicular to the first direction when the controller is detached from the main unit.

A game system comprising:

• a main unit;
• at least one processor;
• and
• a first controller configured for removable attachment to the main unit, wherein
• the first controller is configured to communicate with the main unit via wireless communication when the first controller is detached from the main unit,
• one or more of the at least one processor is configured to process inputs to the first controller for controlling a game, and
• one or more of the at least one processor is configured to process a same first input to the first controller as inputs corresponding to different directions according to whether the first controller is attached to or detached from the main unit.

A game system comprising:

• a main unit;
• at least one processor;
• and
• a first controller configured for removable attachment to the main unit, wherein
• the first controller is configured to communicate with the main unit via wireless communication when the first controller is detached from the main unit,
• one or more of the at least one processor is configured to process inputs to the first controller for controlling a game, and
• one or more of the at least one processor is configured to process a first input to the first controller by a player according to a first interpretation when the first controller is attached to the main unit and to process the same first input to the first controller by the same player according to a different second interpretation when the first controller is detached from the main unit.

A method for a game system comprising a main unit, at least one processor, and a first controller configured for removable attachment to the main unit and including a directional input device, wherein the first controller is configured to communicate with the main unit via wireless communication when the first controller is detached from the main unit, the method comprising:

• processing, by one or more of the at least one processor, a first input to the first controller according to a first interpretation when the first controller is attached to the main unit, wherein the first input comprises an input to the directional input device in a predetermined direction;
• and
• processing, by one or more of the at least one processor, the same first input to the first controller according to a different second interpretation when the first controller is detached from the main unit,
• wherein the first input to the directional input device is processed as an input indicating a first direction when the first controller is attached to the main unit, and processed as an input indicating a second direction different from the first direction when the first controller is detached from the main unit.
