Create your own app logo (logo.bin)
The logo.bin file is the splash screen shown by home menu after launching an app, in this tutorial I'll show you how to customize it. Sorry if it isn't elaborated, I don't have much time.
Requirements.
- Linux (pls don't complain about this, the tools are made for linux, and it's not that difficult to create a Linux boot DVD)
- EveryFileExplorer
- Homemenu secret 20 byte HMAC key (found at 0x206465 decompressed code.bin of EUR homemenu) SHA256: 001ECEFBF56F3614A21532391A7E303CC62A054F5C7BBBF92A97F9C62443AD15

1. Extracting the logo.
The logo.bin file is a lz11 compressed darc, so you can use EveryFileExplorer to extract its contents, save them to a folder. Inside that folder you must see "anim", "blyt", "timg" folders.
2. Creating your own images.
The image files are bclim files, I recommend using files not bigger than 256x256 pixels, because the final compressed logo can't be greater than 8KB. You can use again EveryFileExplorer to create them. Go to "File -> New from file -> Nintendo 3ds plugin -> CTR Layout Images". Tip: There is no need to use transparency on your image, you can set a black background, that will save space.
3. Building the custom logo.
Once you have your bottom and top screen bclim, go to the extracted logo folder, delete everything there and place your files. Name them hblogo_bottom.bclim and hblogo_top.bclim. Download the tools made by Yellows8 and Stevice10 (ctr-logobuilder) and place the extracted logo folder there. Now open a terminal, and type the following:
width: width of your image
height: height of your image
X: X coordinate (left right)->
Y: Y coordinate (up, down)-> Coordinate 0,0,0 is the center of the screen
Z: Z coordinate (3D effect)->
Example: (Both images of 128x32 pixels at the center of the screen.)
The file you want in this case is: customlogo-padded.lz11, use it with 3dstool/ctrtool to build your cia.
Example of logo made with this: Homebrew launcher loader.
Optional: Building an existing logo.
You can use:
to build an existing logo made with private tools. Make sure to use the same settings of the original logo (same panes, groups, etc. Guide yourself with EveryFileExplorer), and make 3 animations, one for Fade In, another for main animation, and other for Fade Out. (Please don't request for the private tools, I cannot share them).

height: height of your image

Y: Y coordinate (up, down)-> Coordinate 0,0,0 is the center of the screen
Z: Z coordinate (3D effect)->
Example: (Both images of 128x32 pixels at the center of the screen.)
Code:
./buildlogo.sh customlogo extracted_logo "128,32,0,0,0" "128,32,0,0,0" XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
