 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.
