The structure of [[nand/title]] appears to be exactly the same as [[SD Filesystem|SD]], except savegames are stored under the [[System SaveData|nand/data/<ID>/sysdata]] directory instead.

The structure of [[nand/title]] appears to be exactly the same as [[SD Filesystem|SD]], except savegames are stored under the [[System SaveData|nand/data/<ID0>/sysdata]] directory instead.

The sub-directory name under [[nand/data]] is the same SHA256 hash over the [[nand/private/movable.sed|movable.sed]] keyY used for the "sdmc/Nintendo 3DS" sub-directory. This nand/data/<ID> directory is the NAND equivalent of the "sdmc/Nintendo 3DS/<ID0>/<ID1>" directory. The nand/data/<ID>/extdata directory contains the shared [[extdata]], and is structured/encrypted exactly the same way as SD extdata.

The nand/data/<ID0>/extdata directory contains the shared [[extdata]], and is structured/encrypted exactly the same way as SD extdata. (ID0 is the first 0x10-bytes from a SHA256 [[nand/private/movable.sed|hash]])
