Title Entry

Total size is 0x300-bytes.

Offset	Size	Description
0x0	0x200	Application name strings
0x200	0x100	Application publisher strings

Entry index for each language:

Entry-index	Icon language filename

Official apps tend to have the title entries' strings set only to English. Some apps don't have certain title entries set at all. In addition, official apps usually (?) don't have the following title entries set: Korean, Taiwanese, and Chinese.

VideoCaptureMode

This is the enum used to determine how gameplay recording can occur, if at all.

Value	Meaning
0	Disabled
1	Enabled
2	Automatic

When this value is 0, gameplay cannot be recorded. When this value is 1, the game must manually sacrifice some of its heap as transfer memory for AM's IApplicationProxy->InitializeGamePlayRecording(). When this value is 2, AM will call NS->BoostSystemMemoryResourceSize(), and allocate the required memory for recording automatically without the usermode process having to do anything.

PlayLogPolicy

AM passes this to pdm:ntfy cmd9.

PlayLogQueryCapability

This is used with AM commands QueryApplicationPlayStatistics and QueryApplicationPlayStatisticsByUid, to verify whether querying the specified titleIDs are allowed. When not allowed, error 0x3E880 is returned.

Value	Meaning	Description
0	None	The specified titleIDs must match the user-process titleID.
1	WhiteList	The specified titleIDs must match the user-process titleID, or one of the titleIDs from PlayLogQueryableApplicationId.
2	All	All titleIDs are allowed.
