Abstract

Linked game controllers coupled to a single input port of a computer game are configured such that all controllers may be active at the same time. One controller is coupled to an input port on the computer game which has both a parallel-bit interface and a bit-serial interface. This controller provides information on its own control function via the parallel interface and information derived from each of the linked controllers via the serial interface. Each of the controllers includes a flag bit, in the provided information, that indicates whether the controller is the last controller in the sequence of linked controllers. The computer game stores data values provided by the parallel interface and then shifts values provided by the serial interface into an internal register until one of the flag bits, indicating the last controller in the sequence, has been shifted. The shifted data is then separated into different control functions which are then provided to the computer game apparatus.

Claims

1. Controller apparatus suitable for use with an electronic game device comprising:

a first controller, configured to be coupled directly to the electronic game device, the first controller including;

first actuator means, configured to be manipulated, for producing a control signal related to the manipulation;

first memory means including means for storing the output signal and means for storing a flag signal;

output means for providing the signal from the memory means to the electronic game device;

a second controller, removably coupled to the first memory means, the second controller including;

second actuator means, configured to be manipulated, for producing an output signal related to the manipulation;

second memory means including means for storing the output signal of the second actuator means; and

means for coupling the second memory means to the first memory means to provide the signal stored in the second memory means to the electronic game device;

wherein the flag signal stored in the first memory means has a first value when the second controller is coupled to the first memory means and a second value, different from the first value when the second controller is not coupled to the first memory means.

2. Controller apparatus according to claim 1, further comprising:

a third controller, removably coupled to the second memory means, the third controller including;

third actuator means, configured to be manipulated, for producing an output signal related to the manipulation;

third memory means for storing the output signal of the third actuator means; and

means for removably coupling the third memory means to the second memory means to provide the signal stored in the third memory means to the electronic game device through the first and second memory means;

wherein the second memory means further includes, means for storing a further flag signal said further flag signal having the first value when the third memory means is coupled to the second memory means and the second value when the third memory means is not coupled to the second memory means.

3. Controller apparatus according to claim 1, wherein:

the first actuator means includes a pointing device which may be manipulated to point in one of a plurality of directions and which produces, as the control signal, a plural bit value indicating one of the plurality of directions in which the pointing device is pointed; and

the output means includes a parallel interface for providing the plural bit value from the pointing device to the electronic game device and a serial interface for providing the flag signal and the signal from the second actuator means to the electronic game device.

4. Controller apparatus according to claim 3, wherein:

the first actuator means further includes switch means which may be manipulated to be in first and second positions for producing a signal indicating one of the first and second positions; and

the serial interface is coupled to the switch means to convey the signal produced by the switch means to the electronic game device.

5. Control apparatus for a computer game device having a processor which accesses data in a memory to execute a game program, the control apparatus comprising:

control input port means for receiving control signals;

register means for storing control signals received from the control input port means and for providing the stored control signals to the memory;

a first controller, having an output port through which control signals are provided to the control input port means and having an input port;

a second controller, having an output port through which control signals generated by the second controller are provided to the input port of the first controller to be provided, through the first controller, to the control input port, the second controller providing, as one of the control signals, a flag signal having a value to indicate that the second controller provides a final control signal to the control input port.

6. Control apparatus according to claim 5, wherein:

the second controller includes an input port and means, coupled to the input port of the second controller for changing the value of the flag signal to an alternate value which indicates that the second controller does not provide the final control signal to the control input port; and

the control apparatus further includes, a third controller, having an output port through which control signals, generated by the third controller, are provided to the input port of the second controller to be appended to the control signals generated by the second controller and which provides a further flag signal as one of the control signals generated by the third controller, said further flag signal having a value to indicate that the third controller provides a final control signal to the control input port.

7. Control apparatus according to claim 6, wherein the first controller includes a parallel interface for providing control signals generated by the first controller to the control input port and a serial interface for providing the control signals generated by the second and third controllers to the control input port.
