By connecting the Family BASIC Keyboard to the Nintendo Famicom, the Family BASIC series let users create and save code in the BASIC programming language. Versions 2.0a and 2.1a both contain the same Mario references.

Custom backgrounds can be made with the "BG GRAPHIC" editor, which supplies the user with pre-made tile designs. Some of the tiles appear to be from several NES games, including Donkey Kong, Donkey Kong Jr., and Mario Bros. The screen shot above shows a design made with these tiles.
