Abstract: A set of components is designed for use with proprietary game console controllers. The proprietary controllers include a first hand-held controller having a transmitter for wirelessly transmitting first control signals corresponding to user-input at the first controller to the game console. It also includes a socket. A second hand-held controller has a cable with a plug which would ordinarily be inserted into the socket of the first controller whereupon the first transmitter would hereinbefore relay second control signals corresponding to user-input at the second controller via the cable to the game console. The set of components “unties” the two controllers and includes a wireless receiver having a plug for insertion to the socket; a cradle for receiving the second controller and including a second transmitter having a second socket into which the plug of the cable is received. The second transmitter transmits the second control signals.
