Sprite Database has good Sprites and Backgrounds (principally from Aracade games, such as Punisher) CVG United as well (they have an Iron-Bat even!), also what I do is: using Visual Boy Advance, I play (eg:) Ultimate Spider-Man, I choose a level in the city, using Ctrl+1/2/3/4/5 you can remove different layers from the game (with Ctrl+5, you remove the layer of the characters and interactuable objects), press Impr Pant and voilá! You have a new background, games with good City backgrounds are Ultimate Spider-Man, Spider-Man: Battle for New York, Spider-Man 3, Spider-Man 2, Daredevil, Fantastic Four: Flame On!, Justice League Heroes: The Flash, Batman Rise of Sin Tzu, Batman Begins, etc.
