Hey,
Its working on all of my Vega rigs. I uploaded the source code of the modified xmr-stak.
The part which activates hbcc and calls the miner is not open source.
If the license of xmr-stack does not allow this, I will delete it. Please let me know.
Looks good, dev fee for your address is completly fine, but I think GNU GPL say that you have to give all source codes if you release it to the public.
EDIT: here is free version
