This is the applet presented when a title displays an error message. See AM_services#Library_Applets.
All errors displayed by this applet get logged and can be viewed under 'Settings' > 'Support' > 'Error History'.
On pre-5.0.0 the specified LanguageCode has to be valid, otherwise a fatal-error is thrown. With [5.0.0+] it will use en-US when the LanguageCode is invalid.

This struct is 0xC-bytes.
- Eula: ErrorCommonHeader.type = 3. Displays the EULA.
- SystemUpdateEula: ErrorCommonHeader.type = 8. Displays the system-update EULA. Uses an additional IStorage containing #ErrorEulaData, from Applet_Manager_services#CreateTransferMemoryStorage with flag=false.

| 0x18 | 0x800 | UTF-8 string dialogMessage |
| 0x818 | 0x800 | UTF-8 string fullscreenMessage, displayed when the user clicks on "Details". When not set this disables displaying Details. |
This struct is 0x1018-bytes.
ApplicationErrorArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader. type=2 and unk_x1=1. |
| 0x8 | 0x4 | u32 errorNumber. Raw decimal error number which is displayed in the dialog. |
| 0xC | 0x8 | LanguageCode |
| 0x14 | 0x800 | UTF-8 string dialogMessage |
| 0x814 | 0x800 | UTF-8 string fullscreenMessage, displayed when the user clicks on "Details". When not set this disables displaying Details. |
This struct is 0x1014-bytes.
ErrorCode
This is an u64 containing the error-code: the low u32 is the module portion which is normally set to module + 2000, and the high u32 is the error description.
ResultBacktrace
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x4 | s32 total entries |
| 0x4 | 0x4*total_entries | Array of Result |
Usage
User-processes should push a common arguments struct (version=0) as well as the Arg struct. Once the applet finishes running successfully, it may return an output storage in some cases. An u8 status value is located at +1, where non-zero indicates error.
