Finally a large and reliable memory card for the Gamecube. The Nintendo 251 memory card will last for ages, having the capacity to fit loads of saved games onto it, as opposed to the other official card from Nintendo that has a mere 59 blocks and could only store about 5-6 saved games. The 251 card is excellent value for money by comparison. It is not as big as some of the other 3rd party cards on offer, but as it is an official card from Nintendo, so you know its will never fail, and you will not lose any of your precious saved games. This new official card renders the old Nintendo 59 memory card almost useless, offering over four time as much storage space at an almost identical price. My only criticism is that this was not the card originally released with the Gamecube. An essential purchase for the Nintendo Gamecube.
