Custom Icons for Twilight Menu

How to install

Download needed icons and place them into sd:/_nds/TWiLightMenu/icons/

Icons should have exact rom name with extension included.
E.g. rom file named gbagame.gba should have gbagame.gba.png named icon placed into icons folder.

You also could use custom icons for folders.

Just name your icon as the folder name
E.g. folder named NDS would have NDS.png named icon.

To use custom back button icon you should name file like ...png
(Yes, triple dot, two for folder name (1) and other for extension delimiter (2))

How to create new icons

Create .png icons

Download either GIMP (free) or Aseprite (paid for prebuild binaries but free if you can compile yourself).

As of this Twilight Menu commit:

The icon is converted from a regular PNG file to the nds banner icon format on the fly, so it’s subject to the same restrictions. 32x32, and no more than 15 solid colors with 1 transparent color. As a fallback, images of the wrong size display as the unknown icon, while images with too many colors will render the extra colors as transparent.

So it means icon should be 32x32 pixels size and 16 colors maximum.

You can set first color in color palette as transparent.
(thats what worked for me at least, both for .png and .bin files)

Edit/draw needed icon how you like it.
Also you can make corner pixels transparent to make icon look nicer.
