Install: copy HIFIEC39.IMG to the player root, update the firmware, then select theme B (midnight black) in the settings.

Firmware 3.9.0 (HIFIEC39) only. Flash at your own risk.

* Previews are rendered from the theme's firmware images. On-screen text is drawn in the player's own font and positioned from photos of the device, so the exact layout may differ slightly.
* Made with AI assistance (Claude); pixel art drawn with code.
