An interfacing device for connecting the processing unit of a computer games system to an external data storage medium has a user-operable selection unit for generating a user-selected address and user-selected data. The user-operable selection unit may comprise user-operable switches or electronic latches that are set by a program in response to selections made by the user by means of a joystick, keypad or any other input device. An address comparison unit compares the user-selected address with the addresses from the processing unit, and a data switching device causes the user-selected data to be substituted for data in the storage medium whenever the compared addresses are the same. Instead of a user-operable selection unit, preselected addresses and preselected data may be stored in a ROM, which in one embodiment changes the way the computer interprets external memory and in another changes the computer's internal memory itself.
An interfacing device for connecting a processing unit of a computer games system to an external data storage medium so as to enable the processing unit to address, and receive data from, different storage locations in the external data storage medium, said interfacing device being removably connectable to the processing unit and to the external data storage medium and comprising means responsive to the processing unit for recognition of a selected address and means responsive to said recognition for modification of data processed by the processing unit.
An interfacing device according to clam 3 wherein the modification means comprises user-operable selection means for generating the selected address and user-selected data and means for supplying the user-selected data to the processing unit in substitution for the data in the addressed storage location of the external data storage medium if the compared addresses are the same.
A method or playing a computer game controlled by a computer games system having an internal processing unit and an external data storage medium, comprising the following steps performed outside the internal processing unit:
An interfacing device for interconnecting a processing unit of a computer games system and an external data storage medium of a kind which is directly connectable to the processing unit, the interfacing device being removably connectable to the processing unit and to the external storage data storage medium to enable the processing unit to address, and receive data from, different data storage locations in the external data storage medium, and the interfacing device comprising:
A method of operating a computer games system in which an interfacing device interconnects a processing unit of the computer games system and an external data storage medium of a kind which is directly connectable to the processing unit, the interfacing device being removably connectable to the processing unit and to the external data storage medium to enable the processing unit to address and receive data from different data storage locations in the external data storage medium, the method including the following steps performed in the interfacing device:
