First comment/post/whatever. Hi there. So, uh. Where exactly does the "2002 E3 demo" bit come from? Hidden Palace lists this as a March 2001 proto, and the title screen of the demo itself says it's an internal build from May 2000. The reference given just links directly to the Hidden Palace download, so there's nothing to be found there, and an article about the release on the French website Dreamcast News (http://www.dreamcast-news.com/) doesn't say anything about E3 or 2002 either. What's the source for this?
