Sprite sheet

UniStores can have a sprite sheet to have icons for the apps, this need to be in .t3x format which can be generated with devkitPro's tex3ds.

To make the .t3x file you will need a .t3s file and image files. The .t3s should contain something like:

--atlas -f rgba -z auto

0.png
1.png

Where 0.png and 1.png are app icons in the same directory. The app icons should be up to 48x48 and the order they are in the .t3s file will be the order for icon_index in their info section.

You can then generate the t3x by running:

tex3ds -i path/to/file.t3s -o path/to/file.t3x
