The error applet is used to display an error result by several titles and applets. (AppletId 0xE)

−

~~A dialog is displayed with~~ the error ~~code at the top, and with support text plus a support page link~~ in ~~the dialog~~.

+

Depending on the type, the applet will display the error in several ways.

It takes two input storages: common arguments and a custom storage.

−

== ~~Common arguments~~ ==

+

== Error applet types ==

−

~~Version 0 according to official usage.~~

+

=== Error (common one) ===

+

Takes a CommonArgs storage with version 0.

−

== ~~Error~~ storage ==

+

==== Custom storage ====

−

~~Has~~ size 20.

+

Unknown exact size, using size 20 seems to work fine.

−

~~Apparently, the layout~~ is ~~changed by setting different values to the first byte~~.

+

The type (byte 0 of this storage) is 0.

−

The error code is ~~an u32/~~Result ~~located at offset 16~~.

+

{| class="wikitable" border="1"

+

|-

+

! Offset || Size || Typical Value || Notes

+

|-

+

| 0x10 || 4 (u32) || 0 (2000-0000) || Result code, same Result used everywhere in HOS.

+

|}

+

The error will display error code 2000-0000 if the Result is not set. The text is the default one.

+

=== SystemError ===

+

Takes a CommonArgs storage with version 0.

+

==== Custom storage ====

+

SDK uses size 4120 for this storage.

+

The type (byte 0 of this storage) is 1.

+

{| class="wikitable" border="1"

+

|-

+

! Offset || Size || Typical Value || Notes

+

|-

+

| 0x8 || 8 (u64) || 0 (0000-0000) || ErrorCode (not Result like in normal errors) of the error to use.

+

|-

+

| 0x18 || 0x800 || - || String of the text to be shown as a short description of the error.

+

|-

+

| 0x818 || 0x800 || - || String of the text to be shown as a more detailed description of the error.

+

|}

+

If the first text is not specified but the second one is, the applet will directly load the "Details" display with the second error text.

+

If both texts are set, the applet will load the dialog with "Close" and "Details" options, and will load the display mentiones above after selecting "Details".

+

If no ErrorCode is supplied, the applet will use 0000-0000.

+

=== ApplicationError ===

+

Apparently similar to SystemError, has type (byte 0 of the second storage) 258, with almost same offsets.

+

More info needs to be added about this type.
