Hi Randy,

I am new member!
Is it possible to make an automatic engine update in picochess v4.2.3 from the latest Stockfish developmentversion.
I have tried to do this manualy in picochess 3.4 bookworm it was easy to replace.
But in picochess v4.2.3 it's very hard to do this.

I'll hope it should be possible, by the way maybe can Johan aslo anser this question!??

Further I am very happy with this current version!!!

You should be able to replace the current version with any newer compile, just like v3. Once you compile the dev version, rename it to StockfishNN, place it in the /opt/picochess/engines/aarch64/NNUE folder and make sure it's executable.
