Hi, sorry i missed your message.
1.9.4 is just a quick patch for Haven, and yes i probably screw up some things.. Im not maintaining the CN version anymore, just wanted to give an option for XHV miners who want to continue using SRBMiner.
For all the rest algorithms just use 1.9.3 version.
No worries.
That's what I assumed as well. The question is, since it was just a quick patch, how much work would it be for you to get it working on those older GCN cards again? Some of them would still be viable in XHV, especially with cheap power.
