This is an unofficial release of Rodent IV with NNUE capabilities. NNUE code has been lifted from Toga NNUE. It uses old (smaller) Stockfish networks and mixes their score with handcrafted Rodent eval. Implementation is not optimal, because NNUE score is calculated from scratch, but still gains about 320 Elo points over handcrafted eval, assuming that default parameters are used.
Now for the best thing. Since it uses NNUE and classic eval simultaneously, and good old personality system is still in place, You can effectively play against rocket-fuelled version of Your favourite opponent.
Download package is quite heavy, because it includes multiple opening books and NNUE file from Stockfish.
This is a one-shot upload, any improvements are unlikely.

Thanks for the new Engine Pawel. Unfortunately only 48 threads are supported. Is it possible to increase the number of threads. Another issue I have noticed is tbs. It seems Rodent does not support syzygy tbs.. Thanks once again for the great engine. Trying now nimzowitch playing style of Rodent.

Pawel, could you make a compile for older CPUs? Rodent nnue just does not work on my AMD a8 system. It would be very kind.
