PURPOSE: To enable a user to select or preset and enhance an ability to be played for a game by recognizing an address selected responding to a processing unit, and changing data to be processed by the processing unit responding to the recognition. CONSTITUTION: An interfacing device has a casing 1, the one end 2 of the casing is connected to the receiving port of the console of a computer game, and the other end 3 of the casing receives a cartridge having an external data storing medium. A printed circuit board 4 having an interfacing circuit is housed in the casing 1. An adjustable switch 5 installed on the upper wall 6 of the casing 1 can be usable for changing the how to play of the game stored in a memory. When a compared data is identical, an action signal is dispatched on a line (L) by an address comparison circuit 15, and then the switching state of a data switching device 17 is changed, thus a combination with the main data bus 12 of a data (Du) for a direct transmission to a main processing unit, and a data transmission from an external memory are prevented. |
