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.

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.

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.

OpenLibraryAppletProxyOld eventually calls the same func as #OpenLibraryAppletProxy, except that the #AppletAttribute is all-zero.

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 a type-0x15 input buffer containing an #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.

No input/output.

GetCurrentLibraryApplet

No input, returns an output #IAppletAccessor.

GetApplicationId

No input, returns an output ApplicationId.

PushLaunchParameter

Takes an input u32 #LaunchParameterKind and an input #IStorage, no output.

GetApplicationControlProperty

No input, takes a type-0x6 output buffer.

The output buffer must be at least 0x4000-bytes. Returns an error when the #AppletId is 0x04, aka when the IApplicationAccessor is for a SystemApplication.

This gets the application control.nacp.

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.

GetFriendInvitationStorageChannelEvent

No input, returns an output Event handle with EventClearMode=0.

This is exposed by sdknso under nn::friends::. This returns a ptr to the cached Event in global state, with the Event being loaded if not previously initialized.

TryPopFromFriendInvitationStorageChannel

No input, returns an output #IStorage.

This uses the same StorageChannel as #PushToFriendInvitationStorageChannel.

This is exposed by sdknso under nn::friends::. When the storage_size is <0x10, this returns false. data_size = storage_size-0x10; Then the first 0x10-bytes from storage are read to stack, which is later copied to the output Uid on success prior to returning. Then the storage is read into the specified output buffer with storage-offset 0x10, where the size is size = data_size > buf_size ? buf_size : data_size. Reading is skipped if size is zero. Afterwards the used size is written to an output param. On success, true is returned.

GetNotificationStorageChannelEvent

No input, returns an output Event handle with EventClearMode=0.

This is exposed by sdknso under nn::notification::. This returns a ptr to the cached Event in global state, with the Event being loaded if not previously initialized.

TryPopFromNotificationStorageChannel

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.

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 #AppletMessage).

[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.

Takes an input #IStorage, no output.

This is not usable under an Application, however it is usable under a LibraryApplet.

Used for sending requests to qlaunch. sdk-nso creates a 0x10-byte storage which is sent to this. The following are the functions which use this, with the data written to the storage:

• RequestHomeMenu 5341 4d53 0100 0000 0200 0000 0100 0000 Returns to the main Home Menu, equivalent to pressing the HOME button.
• RequestJumpToSystemUpdate 5341 4d53 0100 0000 0b00 0000 0100 0000 Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.

GetHomeButtonReaderLockAccessor

No input, returns an output #ILockAccessor.

Similar to using #GetReaderLockAccessorEx with inval=0.

Exit

No input/output.

Exits the current applet. On success, official sw will enter an infinite loop with sleep-thread value 86400000000000.

LockExit

No input/output.

Locks exit process of pressing X to close in HOME Menu for an application or HOME button for an applet. When locked, it will show the "waiting for software to be closed dialog" until UnlockExit is called or a 15 seconds timeout (when the latter occurs, the process is force-terminated).

UnlockExit

No input/output.

Unlocks exit process, if LockExit was previously used.

EnterFatalSection

No input/output.

LeaveFatalSection

No input/output.

#EnterFatalSection must be executed at least once before executing this command, otherwise error code 0x40080 will be returned. EnterFatalSection and LeaveFatalSection work in pairs, that is, N calls to EnterFatalSection must be performed first in order to perform N executions of LeaveFatalSection. Essentially, these two functions operate like how one would lock and unlock a recursive mutex.

GetLibraryAppletLaunchableEvent

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

SetScreenShotPermission

Takes an input s32. No output.

Controls whether screenshot-capture is allowed.

Value	Description

See #AppletMessage.

SetScreenShotAppletIdentityInfo

Takes an input #AppletIdentityInfo, no output.

SetOutOfFocusSuspendingEnabled

Takes an input u8 bool flag. No output.

SetControllerFirmwareUpdateSection

Takes an input u8 bool flag, no output.

This throws error 0x40280 when the internal state flag already matches the input value.

The input value must not be >3.

SetDesirableKeyboardLayout

Takes an input u32, no output.

The input u32 is "nn::settings::KeyboardLayout".

Returns an output u64 LayerId which is then used by the user-process with Display_services#OpenLayer.

IsSystemBufferSharingEnabled

No input/output.

Not available when the current applet is an Application (#AppletId == 0x01).

Checks whether SystemBufferSharing is enabled, throwing an error otherwise.

GetSystemSharedLayerHandle

No input, returns two output u64s "nn::vi::fbshare::SharedBufferHandle" and "nn::vi::fbshare::SharedLayerHandle".

Runs code similar to #IsSystemBufferSharingEnabled first.

GetSystemSharedBufferHandle

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
