Super Mario Bros 3/World Scene Designer by NintenDan
Want to design your own scenes from Super Mario Bros 3 for friends and to post on internet forums? Want something interesting to do because you're bored? Here's NintenDan's official Super Mario Bros 3 Scene Designer/Builder program.
What this program actually does though is allow you to make scenes from Super Mario Bros 3 using the various sprites and backgrounds found in the game. You will eventually be able to choose between all ten or so backgrounds in the game, all the foreground/background objects and many of the enemy sprites and bosses. Heck, there will probably even be Super Mario World sprites and such you can choose.
