Correct, they never published documentation, which has led us to this situation. The lack of "training" for newer crackers is something i even remember empress herself pointing out. There is some crackjng training centering around archaic drm like securom on spore. However cracking groups had gone more and more "closed source".
It's pretty normal for water blocks to come out well after a GPUs release. Also it looks like it was a new product/company so it makes sense the design took longer than the competition.
