I too am on Nemosminer and am looking for a way to insert a d= for specific algos...is that possible with his config? It appears that this method will apply to all algos in that specific miner. I also noticed that the codeing is slightly different in the EWBF miner vs the others...I was looking to add a d= to some of the algos in the ccminers to assign a fixed difficulty setting...
I suggest discussing this on the nemosminer thread, or on its github.
diff would need to be set per algo, which is complicated as the script builds the password for each algo from what i recall.
