It's out of my hands now as it's been sent to DigiByte to use as they see fit. Perhaps you might send them a PM offering your services.

I think it should be relatively easy to clean up (a few AV products generate alerts for the Windows exe, for example) and turn into something DigiByte official (giving credit to previous developers of course).
It's by far and away the most profitable way to mine DGB.
Why make me chase the dev's?

Because the Dev's expressed an interest in making it DGB official. That's a good thing. It'll give clout to the miner eventually released, and will also add to DigiByte's resume as it were.
Anyone who wants to download the current grs-sgminer (warts and all) that let's you use the -k myriadcoin-groestl kernel can do so by downloading the AidBit wallet
http://www.aidbit.net/download/ (be sure to disable your AV beforehand) which installs the windows version along with the wallet install (I believe this is still correct anyway). Then, you'll need to locate your miner install, and independently configure appropriately. For everyone else, I suggest waiting for the DigiByte team to release a new, improved dgb-groestl-sgminer. The Linux version already looks great and ready to go as is, and just needs to be renamed and uploaded to github. The Windows version needs a couple of tweaks and to be made official . . . I think anyway.
I only have remedial code reading abilities, and am not a programmer by any means.
