<P>PROBLEM TO BE SOLVED: To provide a novel game system and a portable game machine. <P>SOLUTION: When power is on, a CPU of the portable game machine executes a startup program and, in step S3, detects a cartridge. When no cartridge is inserted but communication with another game machine is established, according to the startup program, the other game machine in step S11 is requested to transfer a program. In response to the transfer request, the other game machine reads out a program and transfers it to the portable game machine. The portable game machine in step S13 writes the transferred program into a work RAM according to the startup program. After authentication process in step S15, if authentication OK, in step S21 the program written on the work RAM is started and executed. Even if no cartridge is mounted on the portable game machine, a program from another game machine can be downloaded, thereby allowing a network game without increasing the memory capacity of the portable game machine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
