I have a PSP ver 3.52 and i have downloaded some games that are in cso. How do i play the games on my psp? What program do i need?

you need to have custom firmware first

yea u need a cfw of 1.5 official with dh. but when u are on a cfw, u put it in iso folder, i think, coz thats what i do 4 3.52m33-2

u will need to downgrade using pandoras battery and majic memstick

I would suggest waiting before using Pandora's Battery for a few days so some more of the people around give it a spin so you can get more help if you need it.

Its not hard to do if you follow instructions. But the problem for him would be that you need someone on cfw to begin with to get the battery. If youre on 3.52 official Sony fw then you cant play cso files until you downgrade your psp.

If I am correct atm there is no downgrader for 3.52 even using Pan's Batt... I could be wrong.

Pandora's Battery can downgrade any current PSP. This includes 3.51 and 3.52 firmware.

the only problem with pandora is the need of homebrew psp first. i personly dont know anybody with a psp. good thing is i dont need pandora because i have 3.40oe that is not bricked. i am however going to make a jigkik just in case i need one.

Downgrade first to 1.5 then take your pick of the many custom firmwares
