I'd almost be willing to do this at no charge, because I'm a video game fanatic, but it's a lot of work, and I do need money.
I can retrieve information from across the web, include the images, and I can provide download links for most snes games. I'm not entirely sure how long it would take. Finding images is the hardest task. If a game has no screenshot, there's a chance I can create my own. Also, if you want multiple screenshots for any specific game, I'll provide them.
