Just found this to be a better section so moving post here.
So I borrowed 2 authentic PS3 controllers and Mame can see it and configure it for game play. Now I want to buy 2 new controllers and return the borrowed ones. Will these Generic PS3 controllers work just as well?

Also found 2 of these wireless ones. Will they work?
