PSP hack master, neur0n, has released yet another custom firmware — custom firmware 6.38 ME for PSP-1000 and PSP-2000 models.
I’d assume this CFW is similar, if not the exact same as this one, except of course it now works with PSP-1000 models. With that said it is still recommended you have a Pandora battery ready to go … you know, in case the unexpected happens and you render your PSP a brick.
