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

An information processing system comprising a main unit and a controller configured to be removably attached to the main unit, wherein:

• the main unit includes a display;
• communication between the main unit and the controller when the controller is attached to the main unit uses a first communication scheme, and communication between the main unit and the controller when the controller is detached from the main unit uses a second communication scheme different from the first communication scheme;
• and
• detachment of the controller from the main unit causes the main unit to be paired to the controller for the second communication scheme.

An information processing device configured to be removably attached to a controller, the information processing device comprising:

• a first communication unit for communicating with the controller using a first communication scheme when the controller is attached to the main unit;
• and
• a second communication unit for communicating with the controller using a second communication scheme different from the first communication scheme the controller is detached from the main unit, wherein
• detachment of the controller from the information processing device causes the information processing device to be paired to the controller for the second communication scheme.

A game system comprising a main unit, a first controller and a second controller, wherein:

• the main unit includes a display;
• the first controller is configured to be removably attached to the main unit;
• the second controller is configured to be removably attached to the main unit;
• at least when the first controller and the second controller are detached from the main unit, each of the first controller and the second controller transmits, to the main unit, via wireless communication, operation data representing an operation performed thereon;
• detachment of the first controller from the main unit causes the main unit to be paired to the first controller for wireless communication;
• and
• detachment of the second controller from the main unit causes the main unit to be paired to the second controller for wireless communication.
