Oh, maybe. I figured he did the First Moon Barrier Skip and somehow managed to get trigger the Madam Broodal fight.

my theory is that he trigger madam by breaking the moon wall but dont getting it, i cant know if this works because i dont have the console yet. but i am sure he breaks the first moon rocks, because if he doesnt do that, the rocks must be in the clip

syrkl verified that the madame broodal trigger without our first power moon is exclusive to version 1.0.0 of the game https://twitter.com/kehzou/status/940592170158845952

And there is a poll, too. If you want version 1.0.0 banned from Low% speedruns, voice your opinion on this poll: http://www.strawpoll.me/14608431/r The reason why it would be banned is because it saves about 15 seconds in a speedrun, and not everybody has access to that version of the game.

In Low% and Nipple% it saves a lot more btw

well version 1.0.0 shouldn't be banned, just the strat you can do with it
