Then I'll second it, I get 404 errors regularly, and the fanart backgrounds are often from completely unrelated games.

I'm honestly the most surprised that the Bit Corp Gamate hasn't been added yet despite years of requests. It's far more important a system than many that have been added lately. And not trying to be jingoistic, but I'd bet the vast majority of users are English speakers. I think that emphasis should therefore be given to systems with significant English language support. That and the fact that game media from other countries is severely lacking. One other thing I would suggest is adding an actual poll rather than this seldom read post. Oh, and pure homebrew systems like the PICO-8 and its ilk should be the LAST priority. The games are 99% terrible, and there's a never ending stream of schlock that is just not worth cataloging until well after (decades?) their expiration date.
