That is useful, but does not cover what I want to do.
Oh dear. What you wish to accomplish is
really fricking hard. From prior experience editing *
_LZ.bin for
Nintendo splash logos, this shit induces high blood pressure.
So the file you want to edit is:
- 0004003000008F02.cia (USA HOME Menu, or the specific title that houses the icons)
When GM9 encrypted and extracted with HackingToolkit9DS, you get:
- ExtractedRomFS/launcher_LZ.bin
To edit this file and break it down more, you'll need
DarcTool3DS.
You should get a parent folder
launcher_LZ with three subfolders:
Your icons will be found somewhere in
timg. To view these *.bclim images, you'll need
Every File Explorer.
(I haven't clue which exactly are those for systems applets you see on the top row).
To edit and replace the icons, you'll need
png2bclim; you must not exceed dimensions and resolution when replacing these.
If you use colorized images, you have to edit their corresponding *.bclyt files to remove the color filter that'll mask them.
***
Here's where it's the worse: DarcTool3DS might not be enough to repack and compress the edited
launcher_LZ.bin.
If this file requires HMAC encryption, you will have to figure out what its secret key... I'm assuming that guide by Dungeonfire will not require encryption if he was able to hex edit the BCLYT files.

The rest is standard affair rebuild the CIA, blah blah sign NCCH header & version number, GodMode9 *.app encryption.
