The GameCube, like the PlayStation and Dreamcast before it, gets its game data from unwriteable disc media, so, unlike Nintendos cartridge-based games of yore, youll need this accessory to save your place in the game, store your preferences, and preserve the stats of your sports games etc. The GameCube 59 Slot Memory Card is really small--about the size and weight of a poker chip--and comes with 4 MB of flash memory (divided into 59 blocks, hence the name), which should be enough to get you started. If you want to archive all your games for posterity, though, youre going to need more than one...
The 59 Slot Memory Card is an information storage device used to record information such as game progress, high scores and more. This accessory is required to save game progress on the majority of Nintendo GameCube games. The "59" refers to the number of memory blocks on the card. You can save data from many different games on a single Memory Card; however, some games require more memory blocks than others. Please read the games instruction manual to find out how many memory blocks it uses.
