<P>PROBLEM TO BE SOLVED: To provide a game machine that protects more reliably data to be used for a performance which can be executed at predetermined timing after installation of the game machine in a hall. <P>SOLUTION: When a fixed-term performance is selected as a variable performance pattern (Yes in S3101), a VDP and a sound DSP read and decrypt image data and sound data for performing the applicable fixed-term performance (S3102). When the fixed-term performance is not selected (No in S3101), the image data and sound data (not encrypted) for performing the applicable performance are read. The VDP and the sound DSP acquire performance data to perform the fixed-term performance or performance data to perform a performance other than the fixed-term performance (S3103). When the performance is subsequently executed (S3104), the decrypted performance data are discarded (S3105). <P>COPYRIGHT: (C)2013,JPO&INPIT |
