The Nintendo 64 Expansion Pak was an add-on for the Nintendo 64 that doubled the amount of RAM the N64 had to 8MB. This allowed for greater resolution, longer draw-distance, and more detailed graphics. It was bundled with Donkey Kong 64, one of the first games to utilize the hardware. Nintendo published titles that either required or used the Expansion Pak included Donkey Kong 64, The Legend of Zelda: Majora's Mask and Perfect Dark.
