RequestSharedFontLoad

Takes a #SharedFontType (uint32), no output.

GetSharedFontLoadState

Takes a #SharedFontType (uint32), returns the #LoadState (uint32).

LoadState

Value	Description
0x00	Loading
0x01	Loaded

GetSharedFontSize

Takes a #SharedFontType (uint32), returns the Font Size (uint32).

GetSharedFontAddress

Takes a #SharedFontType (uint32), returns the offset (uint32) to the Font Address.

GetSharedFontSharedMemoryHandle

No input, returns an output SharedMemory handle.

User-processes map this SharedMemory with size=0x1100000 and permissions=R--.

Font data is TTF, located at the offset returned by #GetSharedFontAddress.

GetSharedFontInOrderOfPriority

Takes an input u64 LanguageCode and 3 type-0x6 output buffers, returns an output u8 and u32. The u8 is a bool to specify if the fonts are loaded or not and the u32 is the font count. The first buffer contains a list of Shared font types, the second buffer contains the font offsets and the final buffer contains the font sizes. The buffers are an array of u32s which specify information about a specific font. Buffer1[n] is related to Buffer2[n] and Buffer3[n]. Example: Font index 0s offset is at Buffer2[0], size is at Buffer3[0]. The fonts are relative to the shared memory created by #GetSharedFontSharedMemoryHandle

SharedFontType

NotifyAppletEvent

Takes an input u8 event_xF, an u8 event_xC, an u8 event_xD, an u8 event_xE, an u32 event_x8, and an u64 titleID. Returns no output.

When event_xE is 2 this will immediately return 0.

Logs a new #PlayEvent with the following data:

• Clears the 0x10-bytes at +0x10.
• u8 +0xF = event_xF.
• Sets the 3 timestamps.
• Converts titleID and writes it to +0x0.
• u32 +0x8 = event_x8.
• u8 +0xC = event_xC, u8 +0xD = event_xD, and u8 +0xE = event_xE.

After the initial logging, additional code runs with some of the above input params.

NotifyOperationModeChangeEvent

Takes an input u8 inval, no output.

Logs a new #PlayEvent with the following data: clears the 0x20-bytes at +0x0, u8 +0x1C = 0x3, u8 +0x0 = inval, and sets the 3 timestamps.

NotifyPowerStateChangeEvent

Takes an input u8 inval, no output.

Logs a new #PlayEvent with the following data: clears the 0x20-bytes at +0x0, u8 +0x1C = 0x2, u8 +0x0 = inval, and sets the 3 timestamps.

After the initial logging, additional code runs which uses inval.

NotifyClearAllEvent

No input/output.

NotifyEventForDebug

Takes an input type-0x5 buffer containing an array of #PlayEvent, no output.

Gets the system-setting pdm!is_production, the size must be 1 and the value must be 0, otherwise an error is returned.

Each #PlayEvent entry is validated, throwing an error on failure. After an entry is successfully validated, it is written to the log.

Cmd8

Takes an input u8 event_xF, an u8 event_x9, an u8 event_xC, an u8 event_xD, an u8 event_xE, and an u64 titleID. Returns no output.

This is similar to #NotifyAppletEvent.

When event_xE is 2 this will immediately return 0.

Logs a new #PlayEvent with the following data:

• Clears the 0x20-bytes at +0x0.
• u8 +0xF = event_xF.
• Sets the 3 timestamps.
• Converts titleID and writes it to +0x0.
• u8 +0x9 = event_x9.
• u8 +0x8 = 1.
• u8 +0xC = event_xC, u8 +0xD = event_xD, and u8 +0xE = event_xE.

After the initial logging, additional code runs with some of the above input params. This is handled the same as #NotifyAppletEvent, except that the value passed for event_x8 is value 0 here.

Cmd9

Takes an input u8 event_xF, an u8 event_xC, an u8 event_xD, an 0x20-byte struct, an u8 bool flag, an u8 event_xE, an u32 event_x8, and an u64 titleID. Returns no output.

This is identical to #NotifyAppletEvent except for the additional struct/flag params.

When event_xE is 2 this will immediately return 0.

Logs a new #PlayEvent with the following data:

• Clears the 0x10-bytes at +0x10.
• u8 +0xF = event_xF
• Sets the 3 timestamps.
• Converts titleID and writes it to +0x0.
• u32 +0x8 = event_x8
• u8 +0xC = event_xC, u8 +0xD = event_xD, and u8 +0xE = event_xE.

After the initial logging, additional code runs with some of the above input params. This is handled the same as #NotifyAppletEvent, except that when the u8 bool flag is set the input struct is used with this.

QueryApplicationPlayStatisticsForSystem

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.

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

This is signaled when logging a new #PlayEvent which would be available via #QueryAccountEvent, where #PlayEvent +0x18 is 0.

Cmd16

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.

• #QueryPlayStatisticsByApplicationId: PlayEvent +0x1C must be 0, +0xC must be 1, and the titleID must match.
• #QueryAccountEvent: PlayEvent +0x1C must be 1 and PlayEvent +0x18 must be <=1.

The structure of the first 0x1C-bytes are determined by #PlayEventType. For titleIDs/userIDs, the low/high u32 in each u64 is swapped.
