<p>An information processing system and apparatus (P1, P2, ...) and an information recording medium (66) wherein the compatibility of a program between preceding (P1) and succeeding models (P2) is assured without requiring a high cost are disclosed. In such a case wherein different models such as first (P1), second (P2) and third apparatus (P3) are developed successively in time, matching programs (PIEX 1, PIEX 2, ...) for the different models are stored in advance in program ROMs (86) of the respective models. A difference in processing between the different models is cancelled by one of the matching programs (PIEX 1, PIEX 2, ...) to establish matching between the operations of them. Before an application program is executed on any one of the apparatus, the matching program is started up in prior <IMAGE></p> |
