Boxed stage hack?

Uh yeah. Watch the potato quality video. It's already in sudden death at that point. If you encounter the tag CrmS! just quit before the match.

Edit: Well I guess I'm not sure if he hacked, could've been a glitch I suppose... Checked his NNID and it's Pikminlinkfs just for reference

That stage looks like the one where you can test out customs as well as a control scheme. But what makes you think it could be a glitch? A hack would have been the right answer. Then again, the game smacks you with a ban if you hack online, I think.

Someone told me it had something to do with mods, although I thought you were supposed to be kicked if running stage mods or other FG illegal things (like miis, though shofu was able to play a little bit in his video)
