Line 617: Line 621:     
When [[#FileSystemProxyType]] is '''Meta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA [[NCM_services#ProgramId|ProgramId]], then an error is thrown on mismatch.

Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.

These are the 0x300 paths to NCA files for the various filesystems FS can access, beginning with @. They're passed via X descriptors, and returned via various [[Location Resolver services|ncm/lr]] commands.

This is "nn::fssrv::sf::FspPath". This is a 0x301-byte string.
