Abstract
An information processing system and apparatus and an information recording medium wherein the compatibility of a program between preceding and succeeding models is assured without requiring a high cost are disclosed. In such a case wherein different models such as first, second and third apparatus are developed successively in time, emulation programs for the different models are stored in advance in program ROMs of the respective models. A difference in processing between the different models is accommodated by one of the emulation programs to establish compatibility between the operations of them. Before an application program is executed on any one of the apparatus, the emulation program is first started up.
