After some help guys following spending hours(nearly all day) going round all the various psp sites. I have psp firmware 2.71. If i am correct i need to downgrade to v1.5 using the dark_alex downgrader?? I am ok with this bit (I think) but very confused with what custom firmware i then need to load onto the psp so that i can get the best out of it. My main concern is that i want to play iso/cso games on the psp, which custom firmware should i plump for? And where and how do i load this on?? Any help that could be given to this novice in the custom psp world would be greatly aprrecaited!!!
