Here we go… how to dump your own warez on your 1.5 firmware PSP. Will you ruin it? Probably not. But do you really want to go through all this grief just to play Super Mario Brothers in a MAME emulator? I don’t know, man. These geek obsessions of yours aren’t going to bring in the ladies. Only a dash of cologne and maybe a real job. Managing a Denny’s gets you free food, but you have a college degree in CS. Can’t you go work at a bank? Buy a nice car? Maybe stop dumping software onto your PSP? And call your mother once in a while?
