Applet Manager services

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.

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	Returns an #ILibraryAppletCreator.
410	[6.0.0+] GetSystemAppletControllerForDebug	Returns an #ISystemAppletControllerForDebug.
1000	[6.0.0+] GetDebugFunctions	Returns an #IDebugFunctions.

All of these 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.

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):

• Creates TransferMemory using the input buffer and size, with permissions=0.
• Uses #InitializeGamePlayRecording with the TransferMemory.
• Closes the TransferMemory handle, + TransferMemory cleanup.
• Uses #SetGamePlayRecordingState with value 0x1.

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.

BeginBlockingHomeButtonShortAndLongPressed

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

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 set.

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.

GetEventHandle

No input. Returns an output event handle. This is signalled when a message is available with #ReceiveMessage.

ReceiveMessage

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
