To remove the 10% dev fee on b8 version just edit the binary using vi editor :
vi xptminer-sse4-b8
:,$s/RUhMA8bvsr48aC3WVj3aGf5p1zytPSz59o/Your_Address/
(ENTER)
:wq
I'm running Dave's miner and happy to pay 10% since its 30% faster.
And anyway He's already agreed to remove the dev fee in a few more days.
