Nintendo 64 Game Pak is the brand name of the ROM cartridges that store game data for the Nintendo 64. As with Nintendo's previous consoles, the Game Pak's design strategy was intended to achieve maximal read speed and lower console manufacturing costs through not integrating a mechanical drive, with a drawback of lower per dollar storage capacity compared to a disk. From the console's first year from late 1996 through 1997, Game Pak sizes were 4 to 12 megabytes with a typical third party retail price of US$75.99, then available in 32 megabytes in 1998, and finally 64 megabytes from 1999 onwards.
