Badges
Anemone3DS supports badge installation by loading badge images off of your SD card and installing them to the Badge Ext Data. In order to install badges, press X to open the badge menu, or press the extra menu touchscreen icon, then press Right on the D-Pad or the Badge Install touchscreen icon. When badges are installed, first the existing badge extdata (if present) is backed up at /3ds/Anemone3DS/BadgeMngFile.dat and /3ds/Anemone3DS/BadgeData.dat. Then, files are loaded from the /Badges directory.
Anemone3DS user interface with the badge install options indicated.
Any images or archives in the /Badges directory will be installed to the default "Other Badges" set using the Anemone3DS Icon. In order to create custom sets, create a new folder in the /Badges directory with the folder name being the name of the set. Any badge files in that subfolder will be installed to a set with that folder's name. By default, sets use the Homebrew Launcher logo as the set icon, but if a _seticon.png file is present in the folder, that icon will be used as the icon. Set icons must be 48x48, otherwise they won't be loaded.
A sample directory structure is shown below:
/Badges/
| Set1/
| | _seticon.png
| | badge1.png
...
| Set2/
| | badge1.png
...
| badge1.png
In this directory structure, 3 sets will be installed - one named Set1, one named Set2, and one named Other Badges. Set 1 has a custom icon and 1 badge, Set 2 has the default homebrew launcher icon and 1 badge, and Other Badges has the Anemone3DS set icon and 1 badge.
Another example of the directory structure. The default Other Badges set has 8 badges and uses the Anemone3DS set icon, the Pokeballs set has 2 badges and uses the custom _seticon.png, and the Pokemon Crystal Decorations set has 4 badges (1 128x128 png broken into 4 badges) and uses the default homebrew launcher set icon.

Badges can be used as shortcuts to launch system titles. In order to do so, name the badge according to name.<TID_LOW>.png, where TID_LOW is the last 8 digits of the title to launch. For example, a file named Big Lapras Doll.00021000.png would create a badge named Big Lapras Doll that launches the NA System Settings application. This works for badge files larger than a single badge as well - all resulting badges will have the shortcut applied to them.

The 3DS has a hardcoded limit of 1000 badges which Anemone3DS will respect. An attempt to install more than 1000 badges will result in some badges not being installed, potentially at random.
