I wonder if it would be possible to use sgminer to mine scrypt-n instead. I tried to use it but Multiminer report an error saying that the argument "--scrypt-vert" is not recognized by sgminer. Which is normal because sgminer require "--algorithm nscrypt" to work with scrypt-n coins. Can you modify the argument in multiminer for it to work? It would be usefull since everywhere i look sgminer is better to mine scrypt-n anyway. On top of that sgminer is still being develloped and vertminer won't be anymore. The vertminer 0.5.3 doesn't work well at all and 0.5.2 barely work better. It could be a good idea to change the argument and put sgminer by default for scrypt-n instead of vertminer.
It is just a suggestion.
