I was just wondering how you pearl dupe?

I believe it's something like R pumping on a certain frame as you collect the pearl, it's a bit screwy.

When Pearl Duping, you're walking into it and sucking it up into your vacuum at the same time. You can only perform this in a lit room and you have to have an element so you can do a vacuum skip. So you're going to do a vacuum skip right beside the pearl and then you're going to press R immediately while walking into the pearl

Technically by the old definition, pearl duplication would be legal in max% as well, but since it's not even a misc category anymore there's not really anything to worry about there.

Also worth noting that pearl duplication doesn't work in PAL.

oh, really? That's interesting. I wonder why it doesn't work on PAL?
