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.
Returns an #IStorage that gives raw access to nand sectors containing the BCT.
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 | ? | |
| 3 | ? | |
| 4 | GetStorageSize | 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.
