3.03 OE-A is definately the "Golden Firmware". It's better than the plain 1.50 and any other official or unofficial Firmware out there. So stop asking. It has all the strenghts and none of the weaknesses of 1.50. And it's getting better with every update. You can downgrade everytime to 1.50 (Really Senseless). If anyone asks wich is the best Firmware, send him to this Thread. Now with the new Popstation cracked to play nearly any PSX-Game compressed and fullspeed i feel like in Heaven. Dark Alex is definately the King of the PSP Homebrew scene. Muchas Gracias.... For now, i can't imagine how to make this beautiful Firmware any better, but i'm shure it will get better... Anyway. Stop asking this Questions and update your PSP with the new Golden Firmware. SONY definately got owned....
For all the Noobs and Faggods.... Now this Thread makes Sense....
