AM (Applet Manager) provides services for interacting with system applets while abstracting several aspects of power and operation management.

Contains multiple raw images, with at least the following: "NN_OMM_CHARGING_BIN_{begin|end}"(charging icon), low-battery icon, and the Nintendo Switch logo displayed during system boot.

appletAE

This is "nn::am::service::IAllSystemAppletProxiesService".

Cmd Name Notes
100 OpenSystemAppletProxy Returns an #ISystemAppletProxy.
200 OpenLibraryAppletProxyOld ([1.0.0-2.3.0] OpenLibraryAppletProxy) Returns an #ILibraryAppletProxy.
201 [3.0.0+] #OpenLibraryAppletProxy Returns an #ILibraryAppletProxy.
300 OpenOverlayAppletProxy Returns an #IOverlayAppletProxy.
350 OpenSystemApplicationProxy Returns an #IApplicationProxy.
400 #CreateSelfLibraryAppletCreatorForDevelop
410 [6.0.0+] #GetSystemAppletControllerForDebug
1000 [6.0.0+] #GetDebugFunctions

All of these Open*Proxy commands except #OpenLibraryAppletProxy take the same input as #OpenApplicationProxy, with the same user-process retry-loop as #OpenApplicationProxy. These Open*Proxy commands (including appletOE) doesn't seem to usable from processes which aren't actual applets (such as sysmodules), at least for applet-types which aren't already in use.

This service is used by all system non-regular-applications.

The 01000000000010XX system titles use the following applet types(above Open{type}Proxy commands):

  • "qlaunch": SystemApplet
  • "overlay": OverlayApplet
  • "starter": SystemApplication
  • "maintenance": SystemApplet
  • All others: LibraryApplet

OpenLibraryAppletProxy

Returns an #ILibraryAppletProxy.

Takes a reserved input u64(official user-processes use hard-coded value 0), a PID,a process copy-handle(cur-proc handle alias), and an 0x80-byte type-0x15 input buffer AppletAttribute.

Official user-processes use the same retry loop with this as the other Open*Proxy commands.

CreateSelfLibraryAppletCreatorForDevelop

Takes a PID and an input u64 pid_placeholder, returns an #ILibraryAppletCreator.

The cached value loaded from Settings_services#GetDebugModeFlag must be 1, otherwise an error is returned.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, otherwise an error is returned.

GetSystemAppletControllerForDebug

No input, returns an #ISystemAppletControllerForDebug.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, and various state checks must pass, otherwise 0 is returned with no output interface.

GetDebugFunctions

No input, returns an #IDebugFunctions.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, otherwise 0 is returned with no output interface.

The BOTW game uses this GamePlayRecording functionality from the main-nso "nninitStartup" function, with size 0x6000000(96MiB). The official GamePlayRecording-enable code does the following(this will panic on any failure):

This GamePlayRecording functionality presumably enables the video-recording usable starting with 4.0.0.

PopLaunchParameter

Takes an input u32 #LaunchParameterKind, returns an output #IStorage.

Pops a LaunchParameter #IStorage, the storage will be removed from sysmodule state during this.

CreateApplicationAndPushAndRequestToStart

Takes an input u64 titleID and an input #IStorage, no output. titleID=0 can be used to relaunch the current application.

CreateApplicationAndPushAndRequestToStartForQuest

Takes 2 input u32s (loaded from struct #ApplicationAttributeForQuest), an input u64 titleID, and an input #IStorage, no output.

CreateApplicationAndRequestToStart

Takes an input u64 titleID, no output.

Same as #CreateApplicationAndPushAndRequestToStart except without the input storage, official sw uses this when no input storage is specified.

CreateApplicationAndRequestToStartForQuest

Takes 2 input u32s (loaded from struct #ApplicationAttributeForQuest) and an input u64 titleID, no output.

Same as #CreateApplicationAndPushAndRequestToStartForQuest except without the input storage, official sw uses this when no input storage is specified.

CreateApplicationWithAttributeAndPushAndRequestToStartForQuest

Takes an input u64 titleID, a type-0x15 input buffer containing an #ApplicationAttribute, an input #IStorage, no output.

Same as #CreateApplicationAndPushAndRequestToStartForQuest except the entire attributes structure is directly specified via the input buffer. This command replaces #CreateApplicationAndPushAndRequestToStartForQuest, official user-processes no longer use #CreateApplicationAndPushAndRequestToStartForQuest.

CreateApplicationWithAttributeAndRequestToStartForQuest

Takes an input u64 titleID and a type-0x15 input buffer containing an #ApplicationAttribute, no output.

Same as #CreateApplicationAndRequestToStartForQuest except the entire attributes structure is directly specified via the input buffer. This command replaces #CreateApplicationAndRequestToStartForQuest, official user-processes no longer use #CreateApplicationAndPushAndRequestToStartForQuest.

GetDesiredLanguage

No input, returns an output LanguageCode.

SetTerminateResult

Takes an input u32 Result, no output.

For example, in some cases official apps use this with error 0x2A2 then uses svcBreak.

GetDisplayVersion

No input, returns an output 0x10-byte struct.

The output struct is "nn::oe::DisplayVersion". This the DisplayVersion string copied from the application control.nacp, this is always NUL-terminated.

GetLaunchStorageInfoForDebug

No input, returns an output u8 StorageId and u8 StorageId.

Just returns two u8s loaded from state.

BeginBlockingHomeButtonShortAndLongPressed

Takes an input s64, no output.

Official user-processes use hard-coded value 0 for the s64.

Starts blocking the Home button.

EndBlockingHomeButtonShortAndLongPressed

No input/output.

Ends the blocking started by #BeginBlockingHomeButtonShortAndLongPressed.

BeginBlockingHomeButton

Takes an input s64 nanoseconds, no output. The input nanoseconds can be zero.

EndBlockingHomeButton

No input/output.

NotifyRunning

Takes no input. Returns an output u8 bool, which is ignored by official user-processes.

GetPseudoDeviceId

No input, returns an output 0x10-byte "nn::util::Uuid" struct.

The 0x20-byte output data from GetSystemSeedForPseudoDeviceId followed by the 8-byte SeedForPseudoDeviceId from the current control.nacp, is hashed with SHA1. Then "nn::util::GenerateUuidVersion5" is called with the final hash, the output from this is then returned for the Uuid.

SetMediaPlaybackStateForApplication

Takes an input u8 bool, no output.

IsGamePlayRecordingSupported

No input, returns an output u8 bool.

InitializeGamePlayRecording

Takes a TransferMemory handle and an u64 for the size of the TransferMemory. The size must match 0x6000000 otherwise an error is returned.

SetGamePlayRecordingState

Takes an input u32. 0 = disable/pause, 1 = enable/restart.

RequestFlushGamePlayingMovieForDebug

No input/output.

RequestToShutdown

No input/output.

RequestToReboot

No input/output.

ExitAndRequestToShowThanksMessage

No input/output.

Used to exit the application and return to the kiosk menu. Official sw uses #UnlockExit immediately before this.

This throws an error when the cached Settings_services#GetQuestFlag value is 0.

EnableApplicationCrashReport

Takes an input u8 bool, no output.

InitializeApplicationCopyrightFrameBuffer

Takes an input TransferMemory handle, an s32 width, an s32 height, an u64 tmem_size, and no output.

tmem_size must be 0x40000-byte aligned. width must be 1-1280, and height must be 1-720.

User-processes create the tmem with an user-specified buffer with permissions=0. width = 1280 and height = 720.

This is used as an overlay for screenshots.

SetApplicationCopyrightImage

Takes a type-0x45 input buffer, an s32 x, an s32 y, an s32 width, an s32 height, an s32 WindowOriginMode, and no output.

The last s32 is "nn::oe::WindowOriginMode". This should be at least 1.

x and y must not have the negative bit set. width and height must not be <1.

Sets the RGBA8 image for use with #InitializeApplicationCopyrightFrameBuffer. Overrides the current image, if this was already used previously.

SetApplicationCopyrightVisibility

Takes an input u8 bool, no output.

Sets the visibility for the image set by #SetApplicationCopyrightImage, in screenshots. By default it's visible.

QueryApplicationPlayStatistics

Takes a type-0x6 output buffer containing an array of ApplicationPlayStatistics and a type-0x5 input buffer containing an array of u64 titleIDs. Returns an output s32 for actual total output entries.

The number of entries in each array is the same.

See also PlayLogQueryCapability.

This uses pdm:qry QueryApplicationPlayStatisticsForSystem.

QueryApplicationPlayStatisticsByUid

Takes a u128 userID, a type-0x6 output buffer containing an array of ApplicationPlayStatistics and a type-0x5 input buffer containing an array of u64 titleIDs. Returns an output s32 for actual total output entries.

Same as #QueryApplicationPlayStatistics except this uses pdm:qry cmd16, to get playstats specific to userIDs.

ExecuteProgram

Takes an input u32 #ProgramSpecifyKind and an input u64, no output.

ClearUserChannel

No input/output.

Clears the UserChannel used by #UnpopToUserChannel.

UnpopToUserChannel

Takes an input #IStorage, no output.

The input storage is pushed to the UserChannel. This is the same channel used by #LaunchParameterKind value 1.

User-processes create a storage using data specified by the user (written to offset=0 size=inputsize), with max size 0x1000. This storage is then used with this cmd.

GetPreviousProgramIndex

No input, returns an output s32.

EnableApplicationAllThreadDumpOnCrash

Takes an input u8 bool, no output.

GetGpuErrorDetectedSystemEvent

No input, returns an output Event handle with autoclear=false.

This is used by sdknso during applet-application initialization. A seperate thread is setup where event-waiting is handled. When the Event is signaled, official sw will assert.

CreateMovieMaker

Takes an input u64 and handle, returns an #IMovieMaker.

PrepareForJit

Takes no input. Launches title 010000000000003B (currently not present on retail systems) if some context variable is not set, with that context variable being initialized afterwards.

IMovieMaker

Cmd Name
0 #GetGrcMovieMaker
1 #GetLayerHandle

GetGrcMovieMaker

No input, returns a GRC IMovieMaker.

GetLayerHandle

No input, returns an output u64.

0 #CreateLibraryApplet
1 #TerminateAllLibraryApplets
2 #AreAnyLibraryAppletsLeft
10 #CreateStorage
11 #CreateTransferMemoryStorage
12 [2.0.0+] #CreateHandleStorage

CreateLibraryApplet

Takes 2 input u32s #AppletId and #LibraryAppletMode, returns an #ILibraryAppletAccessor.

TerminateAllLibraryApplets

No input/output.

AreAnyLibraryAppletsLeft

No input, returns an output u8 bool.

CreateStorage

Takes an input s64 for the storage size, returns an #IStorage.

This allocates a buffer with the specified size which can then be accessed via #IStorageAccessor.

CreateTransferMemoryStorage

Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an #IStorage.

The user-process creates the TransferMemory with permissions=0.

The TransferMemory is mapped, which can then be accessed via #IStorageAccessor. The input bool controls whether writing to the storage is allowed: #Write will throw an error if this flag is not set.

CreateHandleStorage

Takes an input copy-handle and an input s64, returns an #IStorage. In some cases the s64 must not have the negative bit set.

The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).

Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from #GetEventHandle to check whether a message is available, then if so it uses #ReceiveMessage. The actual handling for message IDs is done in the app itself(see #NotificationMessage).

[7.0.0+] User-processes now use BeginVrModeEx/EndVrModeEx instead of #SetVrModeEnabled. Prior to using using BeginVrModeEx, pctl IsStereoVisionPermitted is used and error 0xD08E is thrown if not allowed by pctl.

caps:su

This is "nn::capsrv::sf::IScreenShotApplicationService".

This was added with 6.0.0.

This can be used by applications to save screenshots.

Cmd Name Notes
32 [7.0.0+] SetShimLibraryVersion Takes a total of 0x10-bytes of input and a PID, no output.
201 SaveScreenShot
203 SaveScreenShotEx0
205 [8.0.0+] SaveScreenShotEx1
210 SaveScreenShotEx2 Takes a total of 0x50-bytes of input, a type-0x15 input buffer, and a type-0x45 input buffer. Returns a total of 0x20-bytes of output.

SetShimLibraryVersion is a wrapper for caps:c cmd33. Commands SaveScreenShot, SaveScreenShotEx0, SaveScreenShotEx1 and SaveScreenShotEx2 are wrappers for caps:sc cmd210.

SaveScreenShot

Takes two input u32s, an u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct ApplicationAlbumEntry.

Official user-processes doesn't use this, instead #SaveScreenShotEx0 is used: ScreenShotAttributeEx0 is all-zero except +0 is set to an input u32.

SaveScreenShotEx0

Takes an input 0x40-byte struct ScreenShotAttributeEx0, an input u32, an input u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct ApplicationAlbumEntry.

Library Applets

This section documents library applet launching.

Before starting the applet, #IStorages are created and written, then passed to #ILibraryAppletAccessor PushInData. The #IStorage session is closed afterwards. The first #IStorage is #CommonArguments, followed by any applet-specific #IStorages.

Once the applet finishes running successfully, #ILibraryAppletAccessor PopOutData can be used to get the applet-specific #IStorage containing the applet output data.

CommonArguments

The first IStorage passed to applets should contain the common library applet arguments. This is populated by nn::la::CommonArgumentsWriter and has the following format.

This struct is 0x20-bytes.

Official sw handles the first 8-bytes separately, which is a header. With CommonArguments version 0x0, the header is 4-bytes, while starting with version 0x1 it's 8-bytes.

Offset Size Typical Value Notes
0x0 4 1 Common Arguments version
0x4 4 0x20 Common Arguments size
0x8 4 Library applet version (API version)
0xC 4 0 Theme color
0x10 1 0 Play startup sound
0x18 8 N/A System tick (see svcGetSystemTick)

ApplicationAttributeForQuest

Offset Size Description
0x0 0x4 See #ApplicationAttribute.
0x4 0x4 See #ApplicationAttribute.
0x8 0x4 [7.0.0+] See #ApplicationAttribute.

This struct is "nn::applet::ApplicationAttributeForQuest".

User-processes copy the first 0x8-bytes (0xC-bytes with #CreateApplicationWithAttributeAndPushAndRequestToStartForQuest/#CreateApplicationWithAttributeAndRequestToStartForQuest) to a #ApplicationAttribute with the rest of the struct being cleared, which is then passed to the actual cmd (CreateApplication*ToStartForQuest).

ApplicationAttribute

Offset Size Description
0x0 0x4 Default is 0 for non-Quest. Only used when non-zero: unknown value in seconds.
0x4 0x4 Default is 0 for non-Quest. Only used when non-zero: unknown value in seconds.
0x8 0x4 float audio volume. Must be in the range of 0.0f-1.0f. The default is 1.0f.
0xC 0x14 Unused. Default is 0.

This struct is "nn::am::ApplicationAttribute". This struct is 0x20-bytes.

Internally AM only uses the first 0xC-bytes from ApplicationAttribute, regardless of the cmd.

Notes

AM-sysmodule will only initialize pdm:ntfy / use pdm:ntfy service commands when the value from pm:bm GetBootMode is not 0x1.
