I have a PSP 1003 (phat) running 6.39 Official Firmware, which I want to put CFW onto, so that I can play my EBOOT.PBP games on.
I found a video that shows instructions on how to make a magic memory stick, followed by how to install 3.80 M33-5 CFW, followed by how to install CFW 5.50 GEN-D3.
I am confused as to whether I need to install only one of these, or 3.80 followed by 5.50? I am not very tech minded so tech jargon would be lost on me. Obviously want the best, so if I only should be installing one, which one please?
