Is there any kind of site out there that has images of what a legit cart looks like for each game? I mean, yeah, there are some telltale signs of a bootleg, but not every cart is painfully obvious, especially if you only have an eBay photo or whatever to go off of. It would be fantastic to know precisely what the art is supposed to be and the exact layout of all the logos and such. I suppose you could still get burned even with that knowledge, but it would definitely be a helpful starting point.
