Hi Everyone,
For those who want to run v4 on an x86_64 Linux machine (running a Debian based OS) I have put together an engine pack that you can use to replace the /opt/picochess/engines folder (backup your original).
Once the PicoChess install scripts are able to set up a PicoChess installation on an x86 system perhaps Johan can provide this package as a resource. Note that some engines might require further apt packages or python modules to run, depending on your current setup.
