WTF? The "cord" is the same for phat and slim PSPs. Its just a normal USB cable. I'm guessing you have never done it and dont know what your talking about. How about you actually get a PSP and try it then after you've tried it you come back and reply.
And whats the difference between this patch and the one released a year ago when Remote Play for PC first came out? I think this is just really old and someone said its new but its not.
