CA 2384594

An entertainment device includes a detachable portable memory capable of communicating with a data processor without using any special mechanical components or increasing processing load on the entertainment device. When a file management system (141) is loaded into a main storage device (232), a register (121) is set at a specific value. Before accessing a flash ROM (140) based on the loaded content, a CPU (231) determines whether the content of the register (121) agrees with a specific value. If they agree, the flash ROM (140) is accessed; if not, the file management system (141) is loaded again.

Le dispositif récréatif de cette invention comprend une mémoire portable amovible capable de communiquer avec un processeur de données sans utiliser de composants mécaniques spécifiques ou augmenter la charge de traitement du dispositif. Lorsqu'un système (141) de gestion de fichiers est chargé dans une mémoire (232) principale, un registre (141) est défini à une valeur spécifique. Avant d'accéder à une mémoire ROM flash (140) sur la base du contenu chargé, une unité centrale (231) détermine si le contenu du registre (121) concorde avec une valeur spécifique. Si oui, on accède à la mémoire ROM (140) flash; si non, le système (141) de gestion de fichiers est à nouveau chargé.
