Hello, Mr @Claymore!
There's a new dual mining method described
hereZilminer based on original ethminer works with your dualminer, but it hangs up somitemes while switching miners.
Maybe is it possible to dual mine Zilliqa in dualminer 12.1?

what i have seen it has same hash as in ETH, so my assumption is not possible to dual mine as both use same mem mining. it looks to me like mining ETH+ETC at once, you know... but i can be wrong of course, im not a pro.
