Well I've found something fairly interesting on a forum. Someone sharing a small selection of sounds that have supposedly come direct from Ben Burtt. He seemed quite vehement that Burtt had sent him these personally, and that people should keep it "on the down low" just in case of any backlash (though Burtt didn't personally suggest there might be such issues)

Another member pointed out that some of the files had exactly the same amount of used sounds as the corresponding archive on the official soundboards, and also exactly the same order. He also pointed out that some of the sounds are the same that can be ripped from various computer games.

Regardless of this, the guy is adamant they're from Ben Burtt

I'm a bit skeptical, however some of these sounds I don't recall hearing anywhere else before. But I could be wrong! I'm just wondering should I upload it on its own, or as part of a themed archive
