I have a PSP Slim on 3.72 Official. I have no homebrew PSP. My old PSP broke and bricked, but I still have the battery, and it works. I saw a video on youtube showing how you can make a PSP battery have Pandora without a homebrew PSP. I plan to try doing that soon. But now, I need to know how to make a Magic Memory Stick without a homebrew PSP. I don't know if this helps, but I downloaded Mrdudes easy Pandora GUI. Once I get my spare memory stick today, I plan to make my old PSP battery a Pandora battery. I need to know if Mrdudes easy Pandora GUI requres a homebrew PSP, and I need to know if i can make my PSP Slim which is at 3.72, on 3.71-M33. Please Reply Back.
