I believe a lot of the video work has been done already NES. A tracker I belong to has a large video collection of SNES videos. I'm not sure what format they are or what quality either though. Unfortunately, the tracker has been down for almost a week. I hope it's just some server issues or something. Of course I won't give any links in here to a tracker, and I won't even think about posting them here if they're in XMV format, but if I do manage to get this collection if the tracker comes back up I'll let you know.
Another alternative of course is to buy them...
http://www.emumovies.com/ordering.htmlI know I'm not going to sit down any time soon and make hundreds of videos if they're already done. I haven't given up on the tracker yet, but it might just be worth $40 bucks just to get it all done. We'll see what the future brings. They're all in .avi format there, so if you or I or somebody else bought them and shared them, it would be no different than sharing the files you put up here before.
EDIT: Screw it. I bought the DVD set and a lifetime membership to the ftp there. $45 with shipping.... I'll check out the SNES videos when I get access and let you know.
If this works, I'll have about 10,000 videos supposedly that could also be used as previews on other emulators if we ever get them working on XPorts emus.
Of course, if anybody else would like to show support to them over there afterwards, that's great. I can imagine the amount of work that it took to compile that collection. That's why it was worth $45 to me not to have to do it myself

(Although I'm sure I have tons of name cleaning up to do now..... grumble grumble....)
