PURPOSE:To prevent forgery of a soft substrate by storing previously the ID data, etc., that can be optionally changed to the soft substrate as well as to an external device when the soft substrate is loaded. CONSTITUTION:A soft substrate 50 is loaded to an external device 60 and the ID data 70 is stored in the memory parts 51 and 61 respectively when the use is started for attachment of a game. Then these data 70 are read out of the parts 51 and 61 when the system is working and compared 80 with each other. When the coincidence is obtained between both data, the system is started. The data 70 can be optionally changed for input to the system. In addition, the different data can be stored for each attachment of the game to make it difficult to forge the substrate 50. |
