When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.

== SetSdCardEncryptionSeed ==
+
== OpenFileSystem ==
−
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.
+
Takes a type-0x19 input [[#ContentPath]] and a [[#FileSystemProxyType]] as parameters. Returns an [[#IFileSystem]].
   −
[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is (usually/always?) all-zero (however in some cases the byte at offset 0x20 is value 0x1).
+
[2.0.0+] This function was removed.
   −
== OpenAccessFailureDetectionEventNotifier ==
+
== SetCurrentProcess ==
−
Takes 8-bytes of input and returns an [[#IEventNotifier]].
+
Takes a pid-descriptor.
   −
[8.0.0+] Now takes an additional 8-bytes of input.
+
== OpenFileSystemWithPatch ==
 +
Takes an input [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
   −
== SetSaveDataSize ==
+
Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
−
Takes two input u64s "size" and "journal_size", and writes them to fsp-srv object member variables.
     −
These variables are normally initialized with 32 MiB (0x2000000) and 16 MiB (0x1000000), respectively.
+
Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.
   −
These variables don't seem to be actually used anywhere else (?)
+
== OpenFileSystemWithId ==
 +
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
   −
== SetSaveDataRootPath ==
+
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
−
Takes an input path, and does snprintf(<fsp-srv object>->m_save_data_root_path, FS_MAX_PATH-1, "/%s", input_path);
     −
This path is normally all-zero. When this path is non-zero, the internal OpenSaveDataFileSystem function will create a DirectorySaveDataFileSystem if the target save is a user-save + a directory exists, instead of the normal savedata filesystem object.
+
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].
   −
== SetGlobalAccessLogMode ==
+
May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.
−
Takes an input u32.
     −
== SetGlobalAccessLogMode ==
+
The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemProxyType]] '''Package'''.
−
Takes an input u32.
     −
== GetGlobalAccessLogMode ==
+
After the [[#FileSystemProxyType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.
−
Returns an output u32.
     −
GlobalAccessLogMode is normally 0.
+
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.
   −
== OutputAccessLogToSdCard ==
+
== OpenBisFileSystem ==
−
Takes a type-0x5 input buffer.
+
Takes a type-0x19 input buffer string and a [[#BisPartitionId]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].
   −
The input buffer is the string to output to the log. User-processes normally include a newline at the end.
+
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.
   −
User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.
+
== OpenBisStorage ==
 +
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.
   −
When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.
+
== InvalidateBisCache ==
 +
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].
 +
 
 +
== DeleteSaveDataFileSystem ==
 +
Takes an input u64.
 +
 
 +
== CreateSaveDataFileSystem ==
 +
Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct which governs creation of a saveMeta file.
 +
 
 +
Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060 meta file size, +4 u8 = 1 meta index which dictates meta file name.
   −
The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).
+
Creates non-system savedata.
   −
== GetProgramIndexForAccessLog ==
+
== CreateSaveDataFileSystemBySystemSaveDataId ==
−
No input, returns two 32-bit values "version" and "program_index".

+
== OpenGameCardFileSystem ==

Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].

* '''nn::fs::fsa::IFileSystem''': The main IFileSystem implementation. Filesystem classes implement this interface, and FS code usually operates on this interface.
 +
* '''nn::fssrv::sf::IFileSystem''': Used for sending an IFileSystem over IPC. Not used outside of IPC code.
 +
 
 +
There are two adapter classes to convert between these interfaces:
 +
 
 +
* '''nn::fssrv::detail::FileSystemInterfaceAdapter''': Allows access to an nn::fs::fsa::IFileSystem via the nn::fssrv::sf::IFileSystem interface.
 +
* '''nn::fs::detail::FileSystemServiceObjectAdapter''': Allows access to an nn::fssrv::sf::IFileSystem via the nn::fs::fsa::IFileSystem interface.
 +
 
 +
When the FS process returns a filesystem, it will wrap the filesystem object in a FileSystemInterfaceAdapter to return it over IPC.
 +
Then when FS application code receives that filesystem, it will wrap the nn::fssrv::sf::IFileSystem object in a FileSystemServiceObjectAdapter before using it.
