Happiness has nothing to do with it. As long as it says "can't go any lower" then you know you have a clean slate to work with (ie- EV 0). Still, Berries are a pain to get in B/W.
Well, if your Happiness is maxed out and your EV's are at 0, then the berry just won't work or be applied. That's what I meant. And yeah, berries in B/W is ridiculous..
