>>7610016Look through the game files. Sometimes they are just saved as sprites in wierd file formats. In Terraria for example, there is a folder called Images where all the sprites are saved as XMB files. To extract them you then have to find a file converter or make your own. Sometimes people already had the same idea and it's easy to find.
If the game backrounds have a parallax effect, they're definitely saved in multiple layers. Then you still have to piece them together in Photoshop. Can be quite tedious.
Or you're lucky and there is a Wiki/Forum and you can just copy it.
Hope this helps.
