Pico Logo

1. General Settings (theme.json)

2. Wallpapers & Setup

DS Frame

These colors will only be applied if custom icons are not used.


Upload your own custom PNG icons. If left empty, default shapes will be used.
You can **[Download these Layout Templates]** as a reference to create your own assets in editing software like Photoshop, GIMP, or NitroPaint.

⚠️ this only works for pico launcher v1.2.0 and later versions ⚠️

4. Background Music (OPTIONAL) [Encoder by kazuki-4ys]

You can also convert and download the audio independently as a .bcstm file without generating a full theme.

Theme Library

Information: I decided against implementing a library on my own; fortunately, the folks at the kernel-themes repository have already implemented a better one. You can check it out here themes.flashcarts.net/pico/.

.bin Theme Decoder

To ensure that the gridcell, gridcellselected, bannerListCell, bannerListCellSelected are displayed correctly with their colours, you must select the .bin file together with its .pltt.bin palette (use Ctrl+Click to select both). If selected on their own, they will be decoded independently as masks.
