+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.
