keydb_helper: I followed your link. That was the same webpage I originally downloaded the KEYDB.cfg file from. ENG version. I can tell the one I just downloaded according to your instructions is bigger by 4Kbs than the one I downloaded a couple of days ago. I wish there were a better way to tell on...

I also have the C6A0.tgz variant and pulled down the latest keydb.cfg this morning and am unable to open the disc. Likely this variant hasn't been cracked yet.
