When I got my PSP, the prevoius owner had it at Firmware 3.5, AKA the Magic Number. If I recall correctly, that was the latest firmware to have a simple .exe downgrader for those interested in homebrew. This is why fate coxed me into immediately upgrading the system before learning this fact, thus sticking me with firmware 3.71, AKA you need Pandora’s Battery. I vowed to leave the firmware alone at this point, hoping that in a year or so someone would finally get around to hacking the newer firmwares.
Then Sony came out with Firmware 3.8 this week, and I immediately broke my promise. This update actually has some new features, and I am hear to report as best I can.
