I’ve wanted an easy-to-use editor for this game for quite some time. GreatEd was a pretty sweet editor for Super Mario Bros., and I’m thrilled that this version for Super Mario Bros. 2 now exists. Moving objects around is drag and drop. Dragging on the edges of a selected object will resize it. You can even change single Goombas or Koopas into a row of 2 to 3 of them just by selecting them and dragging the edges like you’re resizing them. The limits for how things can be laid out in the actual game are fairly clear because the program will just stop you from doing impossible things rather than executing some strange behavior when you try to do them. It would be nice if the program came with some explanation for those limits, though.
