[Reddit] Players are trying to clear every Super Mario Maker 1 level before the April 8th server shutdown. They have less than 400 levels to go.

Already been done, there's a data dump of every MM1 course on archive.org. The dump is dated but it came after level uploads for MM1 were shut down so it should be about as complete as it gets, minus courses deleted by Nintendo before that.

Actually playing anything seems to be quite complex but there's some instructions in the reviews, so it should be doable for someone to set up a replacement server in the future (Pretendo network already has the basics for custom Wii U online running).
