A controllertransmits a unique ID to a console main unitwhen starting communication with said console main unit. The console main unitdetermines 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.
