This is the applet presented when a title displays an error message. See 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.

ErrorContext

This is "nn::err::ErrorContext". This is a 0x200-byte struct.

Offset Size Description
0x0 0x1 Type
0x1 0x7 Padding
0x8 0x1F4 Data
0x1FC 0x4 Result

This is used to set specific error contexts for erpt:c.

Depending on Type, different error report fields will be attached and sent:

ErrorViewerStartupParamCommon

This is "nn::err::ErrorViewerStartupParamCommon". This is a 0x4-byte struct.

Offset Size Description
0x0 0x1 ErrorType
0x1 0x1 IsJumpEnabled
0x2 0x2 Reserved

ErrorViewerStartupParamForApplicationError

This is "nn::err::ErrorViewerStartupParamForApplicationError". This is a 0x1014-byte struct.

Offset Size Description
0x0 0x4 Common
0x4 0x1 Version
0x5 0x3 Reserved
0x8 0x4 ApplicationErrorCodeNumber
0xC 0x8 LanguageCode
0x14 0x800 DialogMessage (UTF-8 string)
0x814 0x800 FullScreenMessage (UTF-8 string, displayed when the user clicks on "Details" and when not set this disables displaying "Details")

[10.0.0+] GetMainAppletApplicationControlProperty is now used internally by the applet, on failure the applet will throw a fatalerr. Hence, ApplicationError can't be used from non-Applications (such as LibraryApplet) anymore.

ErrorViewerStartupParamForEula

This is "nn::err::ErrorViewerStartupParamForEula". This is a 0xC-byte struct.

Offset Size Description
0x0 0x4 Common
0x4 0x1 Version
0x5 0x3 Reserved
0x8 0x4 RegionCode
  • ErrorType = 3. Displays the EULA.

ErrorViewerStartupParamForParentalControl

This is "nn::err::ErrorViewerStartupParamForParentalControl". This is a 0xC-byte struct.

Offset Size Description
0x0 0x4 Common
0x4 0x1 Version
0x5 0x3 Reserved
0x8 0x4 PctlResultRestricted

Used where a Result error would have been displayed with ErrorType=0, for module=PCTL errors with desc 100-119. For this the applet will display the following dialog (without report logging): "This software is restricted by Parental Controls".

ErrorViewerStartupParamForRecordedApplicationError

This is "nn::err::ErrorViewerStartupParamForRecordedApplicationError". This is a 0x820-byte struct.

Offset Size Description
0x0 0x4 Common
0x4 0x1 Version
0x5 0x3 Reserved
0x8 0x4 ApplicationErrorCodeNumber
0xC 0x4 Reserved
0x10 0x8 TimeOfOccurrence (u64 PosixTime)
0x18 0x8 ApplicationErrorCodeCategory
0x20 0x800 Message (UTF-8 string)

ErrorViewerStartupParamForRecordedSystemData

This is "nn::err::ErrorViewerStartupParamForRecordedSystemData". This is a 0x18-byte struct.

Offset Size Description
0x0 0x4 Common
0x4 0x1 Version
0x5 0x3 Reserved
0x8 0x8 ErrorCode
0x10 0x8 TimeOfOccurrence (u64 PosixTime)

The applet does not log an error report for this. Used by qlaunch for viewing previously logged errors via the "View the Error" button.

ErrorViewerStartupParamForRecordedSystemError

This is "nn::err::ErrorViewerStartupParamForRecordedSystemError". This is a 0x818-byte struct.

Offset Size Description
0x0 0x4 Common
0x4 0x1 Version
0x5 0x3 Reserved
0x8 0x8 ErrorCode
0x10 0x8 TimeOfOccurrence (u64 PosixTime)
0x18 0x800 Message (UTF-8 string)

ErrorViewerStartupParamForSystemData
