Controller Pak/Filesystem

Save data management on the Controller Pak is facilitated through a simple proprietary filesystem. Most games that support this Pak have a menu that can be accessed by holding START while turning on the N64. There is 32,768 bytes of SRAM available, which is split into 256-byte sectors referred to as "pages". This allows for a maximum capacity of 128 pages, 5 of which are reserved for the filesystem, and the remaining 123 for user software. A software can created one or more save files, up to a total of 16 files, referred to as "notes".
