MountContent7
Takes an input u32(NCA-type) and an u64 titleID. Web-applet loads the u32 from u32_table[inparam].
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 input u32(same as MountContent7), and an input u64 titleID.
The input buffer is the output string path from nsam GetContentNcaPath.
Returns an #IFileSystem.
OpenBisPartition
Takes an unknown u32 that must be 0 otherwise 0x2EE202.
Returns an #IStorage that gives raw access to nand sectors containing the BCT.
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.
