You don't get stuff for some of the Super Famicom games because it simply doesn't exist in the database so until it is added you will have to get your own or wait for it to be completed. To add your own art you have to 1st source the art from the internet then add it to your Image folder under the appropriate platform under the appropriate image type. So as an example if you had a screen shot from a game that shows the title screen it would go in ..\LaunchBox\Images\SuperFamicom\Screenshots - Title Screens. If it was a box front it would go in ..\LaunchBox\Images\SuperFamicom\Box - Front.
