Layouts editing

This page is for advanced users

If you are new, try to edit texts, images or animations before following this

You need hexadecimal knownledge and a hex editor like HxD
Switch toolbox, it will be used as a preview and comparison, modifications will be done with hex edit
All values are in little endian
Animations can override the layout and make the modifications unseen
If you don't understand something (like little endian for example), go search up online, you can learn more stuff like that!
You are really unlikely to get it to work like you want the first try, keep trying! The more you fail, the more you learn! (This is how I learn all that stuff btw :p)

Open any LZ file you want to look/edit with Switch Toolbox (the entire LZ file, not the layout only!)
Search for bclyt files and open any so you can see what they are (or get a idea at least)
Now you can view the layout, you can move some elements, to select them and edit atributes, you can see them in the hiearchy tab
As I mentioned before, you can't save with switch toolbox because it will completely breaks on the console, on Wii U, it works, but not 3DS (sometimes it can work but it's kinda rare)
Once you know which file to edit, open the LZ file with Karameru, and extract the bclyt file you want to edit
Now, here come the care part, open the same layout in switch toolbox, do NOT move/change anything and directly go to File, Save As and save it in the same directory as the original one but give it a other name (like add "toolbox" at the end of the name for example)
Make your modifications on switch toolbox then, again, go to File, Save As, and again, put a different name (add toolbox edited for example)
Copy/paste the original file to make a backup of it
It should look like something like this:

Now open all of them in a hex editor (except the backup file) and start by comparing the toolbox and toolbox edited file except the headers
Go to the original file and edit it manually using the differences seen in toolbox and toolbox edited file (I will make this part better I promise)
Now you can replace the layout you edited with a hex editor on Karameru and save the archive (Need to put more details here I guess)
