I am currently running 5.00 M33-6. I havent updated my custom firmware in a long time
so I dont know where I should start. I just want to play Pixel Junk Monsters ISO I have and
I want to play the UMD of Parasite Eve 3 I also have. I have a PSP 1000.
Can I update directly to the newest or best firmware or do I have to update to one version
then to another???
Thanks for the help
