I went to start making one last night, gave up for now because for some reason every screen shot I took took 30+ so I am filtering through 500+ images trying to eliminate the duplicates and thats way too much work.

The hardest part about these SNES wallpapers is the multiple layer backgrounds they all pan at different speeds, so if you stich just the forground together the background wont match up, so as a result you have to do each later separately and its a lot of work, DK seems that the 3rd and final background even has its own multi speed pattern but I figure you wont notice that or I can correct it enough in photoshop that you cant notice.
