I do make custom cases for snes games. I have made myself a universal game case with a custom insert for all of my turtles games so that way I don't incur wear and tear on the old cardboard boxes. Not sure if you are interested in something like that but it is ALOT cheaper than buying an actual box. Also the entire box art is there. Front, back and spine so it can be displayed on a shelf like a normal box. Here is a quick pic. If you want more pictures or have any questions let me know.
