All right, now that I figured out how to record Cemu properly...
Yeah, this was created on an emulator. But, if I ever get myself Mario Maker 2, (and a Switch, of course), I will re-create the course.
Looks neat, though the limitations of Super Mario Maker certainly keep it from being as accurate as it could be in another editor/engine. Would love to see it get remade in Mario Maker 2 with the extra slopes and what not.
