The Expansion Pak (拡張パック) consists of 4 MB (megabytes) of random access memory (RAM) — which is RDRAM, the same type of memory used inside the console itself — increasing the Nintendo 64 console's RAM from 4 MB to 8 MB of contiguous main memory. Originally designed to accompany the 64DD disk drive expansion peripheral for its larger multimedia workstation applications, the Expansion Pak was launched separately in Q4 1998 and then bundled with the 64DD's delayed 1999 launch package. The Expansion Pak is installed in a port on top of the console and replaces the pre-installed Jumper Pak, which is simply a RAMBUS terminator. It was bundled with an "ejector tool" (NUS-012) for helping remove the original Jumper Pak.
Game developers can take advantage of the increased memory in several ways, including greater visual appeal. The Expansion Pak is required in order to run three cartridge games, Donkey Kong 64, Perfect Dark, and The Legend of Zelda: Majora's Mask, and all 64DD software. Capcom's Resident Evil 2 uses the Expansion Pak for increasing visual details of environments and monsters, and Perfect Dark has limited gameplay options when the Expansion Pak is not present. Supporting games usually offer higher video resolutions or higher textures and/or higher color depth. For example, the Nintendo 64 all-remade version of Quake II features higher color depth but not a higher resolution when using the Expansion Pak. It is used in StarCraft 64 to unlock levels from the popular Brood War add-on for the PC version of the game. Many games such as Castlevania: Legacy of Darkness and Indiana Jones and the Infernal Machine optionally use the Expansion Pak to add a high resolution 640x480 display mode for games, while other games see the benefit of a smoother frame rate. Certain games, such as Duke Nukem: Zero Hour, offer the user the choice between increased resolution or increased frame rate. The Expansion Pak is available separately as well as bundled with Donkey Kong 64. In Japan, the Expansion Pak is additionally bundled with Zelda: Majora's Mask and Perfect Dark, though the games have been also available separately in other regions. Space Station Silicon Valley is known to potentially crash on startup if the Expansion Pak is present.
IGN celebrated the Nintendo 64 industry's methods in launching and supporting the Expansion Pak, for making a high impact accessory with "immediate and noticeable" effects but which is nonetheless mostly optional.Source: Wikipedia
