I have just recently purchased the PSP slim 3.60. I want to upgrade it so I can start playing games like I used to with my 3.52 m33-4 psp until it broke. Now, I am not too familiar with the PSP slim, and I would like to know what should I do to upgrade my PSP so I can play my iso and cso games. Can someone please just tell me what to do and place me the links please? Thank you.
