Abstract:
A game cassette unit configured to be connected to a game machine having a CPU for a game execution by a user, comprising:a memory which stores a program group including a game selection program and a plurality of game machine programs, and a plurality of decode data defining address conversion rules for said CPU to execute respective of said game selection program and said game machine programs; and a decode controller configured to execute address conversion based on a selected decode data from said plurality of decode data so that address signals outputted by said CPU are converted and thereafter transmitted to address inputs of said memory; wherein: each program belonging to said program group is capable of being executed by said CPU upon a connection of said unit to said game machine; said game selection program is configured to make said user select one program of said plurality of game machine programs; said decode controller selects from said plurality of decode data a game selection decode data corresponding to said game selection program upon said connection of said unit to said game machine in order to execute address conversion based on the selected game selection decode data thereby enabling said CPU to execute said game selection program; and said decode controller further selects from said plurality of decode data a game decode data corresponding to a respective game machine program selected by said user when said user selects said one of said plurality of game machine programs during execution of said game selection program in order to execute address conversion on the basis of said game decode data thereby allowing an execution of said selected game machine program.
