When starting a new game, saved translation dictionary data is selected and
compared with other translation dictionary data. Based on the comparison result,
translation dictionary parts differing from the saved translation dictionary parts
are determined as un-obtained parts. Data corresponding to the un-obtained parts
are then retrieved from the other translation dictionary data and stored in a predetermined
area of a RAM as new translation dictionary data. Further, at a game start, translation
dictionary data of saved data loaded at the beginning of a game and each of translation
dictionary data in a memory card are compared. Based on the comparison result,
translation dictionary parts differing from the saved translation dictionary parts
are determined to be un-obtained parts. Data corresponding to the un-obtained parts
are obtained from each of the translation dictionary data in the memory card and
stored in a predetermined area of the RAM as new translation dictionary data.
