Discovered dtothefourth's interesting Super Mario 2 editor today:

It made me think, what NES games could really use a nice level editor that don't have a good one already?
@rainwarrior That editor feels/looks very similar to Lunar Magic, which makes a lot of sense to do so that users don't have to learn much past what they probably already know.
What I find really interesting is the custom enemy feature, and it's always interesting finding out more about how a game does things through what the editor's like.
