I couldn't really find one on Wikia so I started one. It's not that great right now, but I just started. It only has a few articles, but I'm trying to document every Famicom game and accessory and provide videos for each game.
http://famicom.wikia.com/wiki/Famicom_Wiki (http://famicom.wikia.com/wiki/Famicom_Wiki)
EDIT: I'm also planning to add the publisher of each game somewhere in each article.
Any chance of using MediaWiki instead? Wikia is really unintuitive.
(At least it's not pmwiki. Any tropers here know what I'm talking about.)
