I need some help. This Crystal don't have an embedded network. I have a question, I download separately nnue Network and I don't put the nnue Network in the same directory with engine, but I sepecified full path ( where is the nnue download ed. ) That's All right, no?
Now, my question is : In games the engine use nnue specified in the settings, but if I don't have embedded network in engine , in analysis the engine will use the nnue specified in settings ( full path ) , even if it is not embedded?

Please be kind and answer me correctly.

Can someone answer to my question please?

If the network is built-in, you don't have to do anything. If the network is not built-in, the network must be in the same folder as the engine, otherwise it is useless to indicate the correct path.

please go on releasing Android versions as well
thank you
