PicoChess v3.4 'Trixie' Images [14 Dec 2025]

[RandyR]

Hi Everyone,

I have updated the v3.4 Trixie Desktop image to fix the missing support files required to run Dirk's Chess Transformer implementation of the chess-transformers project by sgrvinod. It is located in the Special & Historical Engines menu. I have also updated the Trixie OS system files.

With the release of Raspberry Pi Imager v2.0.0 you can no longer set up your wifi details within the Imager when selecting a custom image. You will therefore have to set it up after flashing. See the 'v3.4 Desktop Readme.txt' file for options. Another option is to use v1.9.6 of the Imager.

The Lite image is unchanged from the 31 Oct 2025 release.

There is an imager version 2.0.2 at the github. I wonder if anything has changed regarding custom image.

That’s actually the version I tested. It looks like Raspberry Pi dropped support for customizing custom images using the v2 imager. Possibly related to the move to cloud-init with their latest RPiOS images.
