SFFS
SFFS is the name of the filesystem stored on the Wii's NAND, and on both banks of the Wii U's NAND (although the Wii U one has a very slightly revised format). It has a plaintext block of metadata (a superblock), pointing to, through FAT, encrypted (via AES) clusters of data.
Compatibility
[edit | edit source]While NPLL supports reading files from SFFS, neither Wii-Linux, nor linux-wiiu, nor NetBSD can do so.
