Takes a storageID, a pid, a [[NCM_services#ProgramId|ProgramId]], a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]

Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.

Takes a type-0x19 input buffer string and a u32 [[Flash_Filesystem|Bis partitionID]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].

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.

This is accessed using the same commands for SaveData with the same input u8. The [[#SaveDataAttribute]] is the same as DeviceSaveData, except that the [[NCM_services#ProgramId|ProgramId]] field is set to <input ProgramId>. See above regarding [[#SaveDataCreationInfo]].

The 0x10-byte struct passed to [[#CreateSaveDataFileSystem]] has the first 0x5-bytes set to all-zero.
