Well, that's the site from 2000, not 97. If you read it, you'll notice it says it's reopening. There was a few other sites - like Mandi's and the Sinister Six, that had screens. But this was the only major MM site with Eddy featured. I seem to recall it having a large picture of Tango in the past along with sprites and wallpapers to help fledgeling MM sites get into shape, if that helps.
Protoman DID help Megaman fight Dr. Wily in the show, though. So that memory you have ... it doesn't really mean it's from an unaired episode. Either you or the webmaster could have assumed it was unaired.
Back in the day we had far less information than we do now. I mean, the early MM sites were great for the sheer enthusism the fans had and the way everyone made webpages with a unique flavor ... but nobody but Mandi or Red Draco had anything remotely resembling unseen tidbots of information. And it wasn't until the Planet Megaman and Megaman Network days did we have anything close to insider information.
Sorry, but take it from a guy who'se been there, you're remembering wrong. If you won't take my word for it Lysekoid and Gren are also relics of that earlier age, you might want to ask them over at the New Horizon forums.
