ive been a bit out of touch with the whole psp hacking thing lately and havent really been able to get online as im a traveller but ive read a few topics on this forum and now im being told that if i upgrade to the latest firmware i can still have all the benefits of my 1.5 psp? well i mean i can still run iso's without a UMD? and im guessing without even having to use devhook??? is it possible to run homebrew on the latest firmware? (which im assuming is 3.03?) basically all i want is to b able to run iso's and emulate a gba (and occasionally a snes he he) please tell me if im wrong?
