I'm not demanding this or anything. But I'm really close to upgrading to 2.0 for one reason. And thats because the new 2.0 allows Pro duo's to play atrac3plus. I just bought a brand new pro duo just for this... I want to conserve space on the mem card. If someone could hack the PSP and make it so the pro duo's could play atrac3 and atrac3plus that would be a fricken awesome hack I would donate money to you.
