I know this isn't the Nintendo forum but you've got to see this. A guy hacked Super Mario World for his friend to play and created what he called "a-hole levels." These are so insanely difficult it's funny. Some of this makes N+ look like a walk in the park. Anyway, I find it hilarious. I can only imagine creating something like this and inviting my friend over to play the new levels I made.
