AM services

From Nintendo Switch Brew
Jump to: navigation, search

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 OpenLibraryAppletProxy ( [3.0.0+] OpenLibraryAppletProxyOld) 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.

All of these commands except #OpenLibraryAppletProxy take the same input as #OpenApplicationProxy, with the same user-process retry-loop as #OpenApplicationProxy.

This service seems to be used by all system non-regular-applications.

OpenLibraryAppletProxy

Returns an #IApplicationProxy.

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):

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

NotifyRunning

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

InitializeGamePlayRecording

Takes a TransferMemory handle and an u64 for the size of the TransferMemory.

SetGamePlayRecordingState

Takes an input u32.

appletOE

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

Cmd Name Notes
0 #OpenApplicationProxy

This seems to be used by all(?) regular-applications, even flog.

OpenApplicationProxy

Returns an #IApplicationProxy. See #appletAE.

Takes a reserved input u64(official user-processes use hard-coded value 0), a PID, and a process copy-handle(cur-proc handle alias).

On failure, official user-processes will retry using this command in a loop while the retval is 0x19280, with svcSleepThread(10000000) being called first.
