Doubling the memory of the N64, the
Expansion Pak allows you to increase the graphics, save games and access certain elements of some games.
Although optional on most N64 titles, there are a few that won't work without the Expansion Pak--the likes of Donkey Kong 64 and Zelda--The Majora's Mask to name but a few.
If you are a hardened N64 Gamer, then this is a must have to take your N64 to the next level, if not however, it might be worth waiting until you get that game that needs it. --Stuart Miles
