I think he could have been speaking in a rhetorical mode or been misquoted. I'm pretty sure he and everyone else know where the stuff came from.
In the beginning, no. No one really knew about it until That Day, and I think the blog author is trying to divide the story into time frames, so episode 3 represents what was known at the time, and tomorrow we'll know what happened then. Alternatively, he doesn'tknow/remember the evidence presented, which was by Matt (Kitsch). Perhaps we'll hear about that in episode 4, so I won't say anything more about that right now.
I think the confusion about the country, "a couple guys in like Germany or Belgium" is genuine on Logan's part. The guys who originally made the microcontroller firmware were two Polish students, but the matter was confused because the schematic was hosted by a German guy, Reiner Ziegler who has a site about Gameboy-related and other stuff. (http://reinerziegler.de/readplus.htm). Many people were confused about the exact country because of this, I think. Then to add to the confusion, the Chinese "Smartboy team" made a cartridge from the same design and hosted a page under smartboy.ugu.pl (long since defunct). I don't know if they did this on purpose to appear like they were the original designers, or if that's just the first free web host they could find.
