ok i got a psp off ebay with 3.40 OE-A. because i didn't think i could do all that downgrading myself.lol so now how do i start playing psp iso off of it? i haven't got a card yet because i'm broke,but plan to get one soon a 2GB or a 4GB one. but when i do what all is needed to and how to use it i tryed to read thro them guides but everything i was reading sounded like you can mess up your psp eazy is it really that hard to just load up a iso from your psp? maybe i just read to much to soon and i am tired but do you need a emu to run the iso sorry to bug you nice ppl i'm just scared to death i'll mess my psp up or brick it.lol or it'll upgrade some how without me meaning to then it'll be a useless pecie of crap and won't play iso i keep reading ppl do it all the time so i'm almost scare to mess with it.lol plus if i play any umd game will it upgrade on its own? or will it ask me first before it trys that,because if it does it on its own i'll stick to iso only.lol thanks again and i did try to read the guide they just seemed complex to me maybe i was reading the wrong thing who know if someone could just put it out in a eazy step by step that be nice sorry again but maybe someone can put my fears to rest thanks again!!
