Ok, first I used to have a phat psp. Sold it a couple days ago on ebay and am getting a slim psp. I want to put CUstom Firmware on it. I have a pandora battery and its been made but do u have to do it a certain way for it to work for the slim? Because then do i need a phat psp? Or am i screwed? Ive used it on my phat psp and it works. Do i just need to put certain files on my memory stick to install CFW on the slim? Or do i need to start over with the battery?

You just need to put the files on the memory stick.
(But you can only install CFW, theres no 1.50 support on slim)
