StartFirmwareUpdate

Takes a total of 0x20-bytes of input, 2 handles, and returns an output handle.

[3.0.0+] Now takes a total of 8-bytes of input, and no longer uses any input/output handles.

GetFirmwareVersion

Takes a total of 8-bytes of input, and returns a total of 4-bytes of output.

[3.0.0+] Now returns an additional 0xC-bytes of output.

GetDestinationFirmwareVersion

Takes a total of 8-bytes of input, and returns a total of 4-bytes of output.

[3.0.0+] Now returns an additional 0xC-bytes of output.

DiscardFirmwareInfoCacheForRevert

Takes a total of 8-bytes of input, and returns a total of 5-bytes of output.

[3.0.0+] No input/output.

UpdateControllerColor

Takes two input u32s for the colors, an input u64 UniquePadId, and no output.

A state flag must be clear, otherwise an error is thrown. Afterwards, this flag is set.

Sends the spi-write subcommand to the specified controller, for writing the color data. This writes to offset 0x6050 size 0x6, where the first 3-bytes are from the first u32 and the remaining 3-bytes are from the second u32.

UpdateDesignInfo

Takes 4 input u32s for the colors, an input u8, an input u64 UniquePadId, and no output.

A state flag must be clear (same as #UpdateControllerColor), otherwise an error is thrown. Afterwards, this flag is set.

Sends the spi-write subcommand to the specified controller, for writing to offset 0x6050 size 0xD. The first 3-bytes from each u32 is used for the spi-write-data, with the u8 being copied immediately afterwards the color data.

GetUniquePadDriverState

Takes a total of 8-bytes of input, returns a total of 0x20-bytes of output.

[9.0.0+] Now takes a total of 8-bytes of input, returns a total of 0x18-bytes of output.

GetSixAxisSensorDriverStates

Takes a total of 8-bytes of input and a type-0xA output buffer, returns a total of 8-bytes of output.

[9.0.0+] Now takes a total of 8-bytes of input and a type-0x6 output buffer, returns a total of 8-bytes of output.

ReadSerialFlash

Takes an input TransferMemory handle, an input u32 offset, an input u64 size, and an u64 UniquePadId, no output.

Reads from the specified controller's spi-flash. The input size is the original size without page-alignment. The TransferMemory permissions is RW-.

This doesn't seem to be usable?

GetUniquePadDeviceTypeSetInternal

Takes a total of 8-bytes of input, returns a total of 4-bytes of output.

[9.0.0+] Now takes a total of 8-bytes of input, returns a total of 1-byte of output.

GetAbstractedPadHandles

Takes a type-0xA output buffer containing an array of u64 AbstractedPadHandle and returns an output s32 for total entries.

Returns a handle for each controller detected by the system.

GetAbstractedPadState

Takes an input u64 AbstractedPadHandle, returns an output #AbstractedPadState.

GetAbstractedPadsState

Takes a type-0xA output buffer containing an array of u64 AbstractedPadHandle, a type-0x22 output buffer containing an array of #AbstractedPadState, and returns an output s32 for total entries.

SetAutoPilotVirtualPadState

Takes an input s8 AbstractedVirtualPadId and an input #AbstractedPadState, no output.

UnsetAutoPilotVirtualPadState

Takes an input s8 AbstractedVirtualPadId, no output.

Clears AutoPilot state for the specified pad.

UnsetAllAutoPilotVirtualPadState

No input/output.

Same as #UnsetAutoPilotVirtualPadState except this clears state for every pad.

AttachHdlsWorkBuffer

Takes an input TransferMemory handle and an u64 for the TransferMemory size, no output.

Official user-processes use TransferMemory size=0x1000 and permissions=RW.

This TransferMemory is used as input/output by the other Hdls commands.

Hdls is for virtual HID controllers.

ReleaseHdlsWorkBuffer

No input/output.

DumpHdlsNpadAssignmentState

No input/output.

After using this cmd, the output #HdlsNpadAssignment is located at tmem+0.

DumpHdlsStates

No input/output.

After using this cmd, the output #HdlsStateList struct is located at tmem+0.

ApplyHdlsNpadAssignmentState

Takes an input u8 bool, no output.

Prior to using this cmd, the input #HdlsNpadAssignment is written to tmem+0 by the user-process.

ApplyHdlsStateList

No input/output.

Prior to using this cmd, the input #HdlsStateList is written to tmem+0 by the user-process.

The #HdlsState will be applied for each HdlsHandle. If a HdlsHandle is not found, code similar to #AttachHdlsVirtualDevice will run with the #HdlsDeviceInfo, then it will continue with applying state with the new device.

AttachHdlsVirtualDevice

Takes an #HdlsDeviceInfo, returns a 8-byte HdlsHandle.

DetachHdlsVirtualDevice

Takes an input 8-byte HdlsHandle, no output.

SetHdlsState

Takes an input #HdlsState and an input 8-byte HdlsHandle, no output.

AbstractedPadState

Offset Size Description
0x0 0x4 Type, only 1 bit can be set. Converted to #HdlsDeviceInfo::type internally by #SetAutoPilotVirtualPadState.
0x4 0x1 Flags. #SetAutoPilotVirtualPadState only uses bit0: when clear it will skip using the rest of the input and run #UnsetAutoPilotVirtualPadState internally.
0x5 0x3 Padding
0x8 0x4 RGBA Single Body Color
0xC 0x4 RGBA Single Buttons Color
0x10 0x1 Type2. See #HiddbgHdlsDeviceInfo::type2.
0x11 0x3 Padding
0x14 0x24 #HdlsState. Unknown if the last 4-bytes are included in this struct, #SetAutoPilotVirtualPadState/#hiddbgGetAbstractedPadsState only uses the first 0x20-bytes.
0x38 0x60 Unused with #SetAutoPilotVirtualPadState/#GetAbstractedPadsState.

Normally the input state is merged with an existing controller selected by Type. However in some cases (BIT(2-5) with type2!=0x2 and BIT(31)) it's detected as a dedicated controller.

Type:

GetMaskedSupportedNpadStyleSet

Takes an input u64 AppletResourceUserId, returns an output u32 #NpadStyleTag.

Official sw uses the output from GetAppletResourceUserIdOfCallerApplet with this.

GetUniquePadsFromNpad

Takes an input u32 #NpadIdType, a type-0xA output buffer, and returns an output u64 for total output entries.

The output buffer contains an array of u64 UniquePadId.

SetVibrationMasterVolume

Takes an input 32bit float.

GetUniquePadIds

Takes a type-0xA output buffer, and returns an output u64 for total output entries.

The output buffer contains an array of u64 UniquePadId.

This is "nn::hid::system::NotificationLedPattern".

This is a 0x48-byte struct.

The above descriptions in the table are based on the info from here.

argdata in the subcommand is initialized as follows: ((u8*)cmd_argdata)[pos] = u8_in[pos2] | u8_in[pos3]<<4; Hence, 4bits from pairs of 2-bytes of the input struct are combined to write to the subcommand. Only the low 4bits of each used byte in the struct is used. This is written to stack initially, then copied to the actual cmd_argdata (the data immediately following the subcommandID byte). There's a total of 0x1B-bytes of cmd_argdata initialized from this.

The layout of cmd_argdata is as follows:

Offset Size Description
0x0 0x1B See above.
0x1B 0xB Cleared to zero.
0x26 0x5 Unused
0x2B 0x8 Set to an input value, which is hard-coded 0.
0x33 0x2 Set to value 0.
0x35 0x1 Set to value 1.
