hey people, i hope ur all doin fine. i got my 2GB memory for my psp yesterday and i have been surfing the net 2 days strait, i want to know how to run iso games on my psp. i upgraded or downgraded my psp to version 3.02oe-a and i have the iso file in the root and i have killzone and it's working like a charm, but as for mortal kombat; i try to run it but the screen turns black and stays like that, untill i press home and go back to the main screen... can i run new games like metal gear solid: portable ops? if i have 3.02oe-a do i need devhook? please help me out, don't give me a link to a long ass tutorial, i went through a lot of these but they don't help. thanks everyone.
