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.

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.

IApplicationFunctions
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.

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

Calls sdk func nn::fs::EnsureApplicationSaveData. qlaunch also calls this same sdk func directly.
Creates the various savedata as specified by the application control.nacp when the savedata doesn't exist.
Official user-processes launch the dataErase LibraryApplet depending on the Result, the above output size is used with this.
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.

Takes an input s64 "nn::TimeSpan", no output.
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.

Takes an input u64 size and a TransferMemory handle, returns an #IMovieMaker.
Official sw retries using the cmd in a loop on error 0x8D4 with svcSleepThread(100000000) being used first.
Official sw uses permissions=None for the TransferMemory, with an user-specified buffer. The size of the buffer used by official sw is 0x6000000.
PrepareForJit
Takes no input. Launches the jit-sysmodule if it has not already been launched for the current application, storing a std::shared_ptr<> for jit-sysmodule process tracking object as an IApplicationFunctions member.
~IApplicationFunctions() includes:
if (this->jit_process) {
Terminate(this->jit_process);
this->jit_process = nullptr;
}
Thus the lifetime of the jit sysmodule is tied to the application which uses it, and each application gets its own fresh copy of the jit sysmodule.

ICommonStateGetter
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.

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 |
