A controller 20 transmits a unique ID to a console main unit 10 when starting communication with said console main unit 10. The console main unit 10 determines whether the received unique ID has already been registered in a wired controller No. registration table, and when it has already been registered, sets already registered correspondence for corresponding a virtual controller No., a wired controller No., and the unique ID. Otherwise, if it is not yet registered, a wired controller No. and the unique ID are corresponded, and new registration and correspondence setting for corresponding them to a virtual controller No. is conducted. The virtual controller No. corresponded to the unique ID is associated to predetermined information processing if the already registered correspondence setting or new registration and correspondence setting is completed.
