PURPOSE:To provide a game machine system allowing a game using the coded program difficult to recover the original program when decoded. CONSTITUTION:The prescribed data (a) are extracted to form a coded program based on the set information (y) of program data X. The decoding key data A are obtained by the calculation of the function F(Z) using the inherent information Z of a game machine executing the program data X for the prescribed data (a) as a variable. The function F(Z) is reversely calculated to the key data A to generate prescribed data (a), the set information (y) is read out from the inputted coded program, the coded program inputted to which the prescribed data are inputted (a) is inserted based on the set information (y), and the original program data X are recovered and executed. |
