A Memory Card is a small device used to save data for games played on the Nintendo GameCube.
One needs a memory card in order to save the things they've accomplished or collected in Super Smash Bros. Melee. In addition, saving data from the game Pikmin on the same card as the player's Super Smash Bros. Melee data will award them the Captain Olimar trophy.
Super Smash Bros. Melee save data takes up 11 blocks on the memory card, while snapshots can vary from three to ten blocks each. Pikmin takes up 27 blocks.
