As I was looking at the different categories of this game, I wondered about what other categories can be done. The suggestion I had was single world speed runs, where a person has to complete every level in a world. It doesn't matter if you complete the level by the regular or secret exit, only that you complete all the levels on the world map.

It's best to do this on a completed save file, and you need a save file with all the coins collected to do an attempt on world 9.

If i did a run where all four players are my mii so i score after serving, is that within the rules? I am also wondering if i can use a second controller for boxing to avoid taking punches, and that once the other mii falls, they dont get up.

Should I speedrun with a new Mii for lower level CPUs? I did a speedrun with my Mii, and had some high level opponents.
