3DS:Error screens

There are multiple kinds of errors that can appear on the 3DS.

Nintendo error screen
The stock error screen. This occurs on stock firmware or old Luma3DS versions without the custom ErrDisp.

See 3DS:Error_screens/Nintendo_error_screen for known fixes to some of these.

Luma3DS ErrDisp
Luma3DS replaces the stock ErrDisp to show more information about an error.

See 3DS:Error_screens/Luma3DS_ErrDisp for known fixes to some of these.

Luma3DS exception screen
See 3DS:Error_screens/Luma3DS_exception_screen for known fixes to some of these.
