Hey, I have an old PSP I got from a relative since he's not using it anymore. It's a PSP Fat, and last time I put my hands on it, I upgraded it to 5.00 M33-6. It's been a while since I was in the PSP scene so I'm not sure what to install to it. I want to play PSX games primarily (FF series and Chrono Cross first comes into mind) Lurking a while, I found installing 6.20PRO will be the best solution (I want the firmware to be still even after a cold boot) Since installing that requires me to upgrade my PSP to official 6.20, I wanted to make sure if I'm in the right path or not. Or any other cfw suggestions?
