Anybody managed to dual mine ? If so ... I need to edit something in this section for ETH intensity ?
if [ $COIN == "DUAL_ETH_SC" ]
In windows I had -ethi x -dcri y . Here I see only dcri. I have to add ethi on that line or on top of the oneBash in the ETH_EXTENTION_ARGUMENTS section ?
So many new things since I first found this 3 weeks ago

You should only need to switch:
COIN="DUAL_ETH_SC"
at the very top of oneBash
there is a hardcoded -dcri 70 for this coin selection, you can add -ethi x with:
ETH_EXTENTION_ARGUMENTS=" -ethi x"
where x is an integer
