MountContent7

Takes an input u32 (NCA-type) and an u64 title-id. Web-applet loads the u32 from u32_table[inparam]. Only type4 is usable with this?

Returns an #IFileSystem.

Note: web-applet strings refer to both this cmd and the below "MountContent" as "MountContent".

MountContent

Takes a type-0x19 input buffer, an in32, and an input title-id.

The in32 must be 5 if the NCA type is 0 (control).

The input buffer is the output string path from nsam GetContentNcaPath.

Returns an #IFileSystem.

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.

OpenBisPartition

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.

MountContentStorage

Takes a #ContentStorageId. Invalid values return 0x2EE202.

Returns an #IFileSystem with NCA files. The read data from these files is identical to the data read by Content_Manager_services#ReadEntryRaw.

OpenDeviceOperator

This command returns a session to a port implementing the #IDeviceOperator interface.

OpenSdCardDetectionEventNotifier

This command returns a session to a port implementing the #IEventNotifier interface.

OpenGameCardDetectionEventNotifier

This command returns a session to a port implementing the #IEventNotifier interface.

IStorage

This is the interface for a raw device, usually a block device.

Cmd	Name	Arguments
0	Read	Takes a type-0x46 buffer, an offset and length
1	Write
2	Flush
3	SetSize
4	GetSize	None

IFileSystem

There are two main implementations of this interface:

RomFS: Filesystem implementation statically linked in the binary. Uses an #IStorage interface as underlying raw device.
IPC proxy: Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.

GetGameCardUpdatePartitionInfo

Returns a titleID and the title-version for it.

Output u32 with ARMS-gamecard: title-version v131162. This is the title-version for 2.1.0, which is the sysupdate included with this gamecard. Launch-day gamecards return title-version v450.
Output u64 with ARMS-gamecard: titleID 0100000000000816.

NS appears to only use this with Content_Manager_services#GetTitleIdInfo and Content_Manager_services#GetUpdateTitleList with storageid=nandsys, for checking whether a sysupdate is required.

BisPartitionID

0: This gives raw access to nand sectors containing the BCT.
