Start from a preset, then adjust anything.
0% turns the LEDs off.
Approximate — the device uses its own bitmap title font. Icons and colours are exact.
Click an icon to replace it with your own image (PNG, SVG, JPG). It's scaled to 48×48 and reduced to a 1-bit mask — the launcher tints it to match the theme, so only the shape matters. Transparent PNGs work best. Click a replaced icon again to re-upload, or use invert / reset below it.
Used throughout the launcher's own screens — settings, install, USB and so on.
These are exactly the icons the device offers when you give a firmware slot its icon — right after installing, or later under Settings → Icons. Restyle these and your Bruce / Flipper / custom tiles change with them. A few (flash, USB, Wi-Fi, PIN, theme) also show up elsewhere in the menus.
Drop in an animated GIF (or WebP/APNG, or several still images) and it's
converted into the launcher's frame format automatically — cropped to the screen's shape,
resized and written as .raw frames.
Easiest — over Wi-Fi:
on the device pick WiFi in the main menu, join the hotspot it shows, open
http://192.168.4.1 and upload this .zip. It's unpacked on the device for you.
/catcolor folder on the SD card, so you get
/catcolor/<your-theme>/. (Not /themes — Bruce uses that one.)
Windows can silently encrypt files copied to removable drives, renaming them to
theme.txt.PFILE, icons.bin.PFILE … and adding an $EFS
file. The launcher can't read those — the theme looks missing. If you see
.PFILE names on the card, delete them and copy the pack again with that data
protection turned off (it comes from a Windows Information Protection / "personal data
encryption" policy). Extracting the ZIP directly onto the card, rather than copying
already-extracted files, usually avoids it too.
