发明名称 Fremgangsmåte og system for å hindre anvendelse av en uautorisert ytre lagerenhet
摘要 A hand-held electronic game machine includes a computer (22) accommodated in a case and a liquid crystal display (LCD) panel (14). When an external memory (16) is inserted to a receiving port (68), a first character data being set in advance in the computer (22) is compared with a second character data stored in a predetermined area of the external memory (16). Prior to such comparison, the computer displays the characters represented by the second character data on the LCD panel. If the first and second character data are coincident with each other, the computer (22) can access to the external memory (16).
