Nintendo 64 N64 Memory Card

The Controller Pak is a memory card that fits inside the controller and allows the player to save their game. While most games allow you to save directly to the cartridge, some require this memory card.

Nintendo's Controller Pak has 256 kilobits (32KB) of SRAM memory, divided into 123 "pages" and limited to 16 save files.

A save file manager can be accessed by pressing the start button when launching a Controller Pak-compatible game.
