You must notify the user of the content of errors returned by specific libraries.
The Wii U requires errors to be displayed for the following libraries. The Error Viewer also includes error messages for libraries other than the libraries listed below. Use of the Error Viewer to display error messages for those libraries is optional, but Nintendo recommends it.
File System
FS and SAVE libraries
Communication-Related
Errors in communication-related libraries (such as FP, ACT, AC, NEX, BOSS, OLV, and Pia libraries)
An exception to this rule is if the user would not be disadvantaged if the error is not displayed. Below are some examples.
When the application automatically retries an operation and completes it without any problems.
When the application can resolve the error without displaying it to the user.
During (background) processes that do not involve active user interaction and when there is no adverse effect on game progress.
Furthermore, in order to ensure smooth operation of user support services, independently changing or creating error codes is prohibited. If you wish to create your own error codes, contact Nintendo at support@noa.com in advance.
For details regarding error display, see the Wii U Error Viewer Package and the Function Reference Manuals for the libraries.
