Do you have the older brick or the newer slim version? If you have the newer version the only hack I know of is using what is called a Pandora's battery and memory card. By switching a jumper on the battery you will have access to modify the PSP. These can be found online and with instructions for around 50 bucks. Easiest way to do it. I'll check when I get a chance what emulator I am running. Can't think of it off the top of my head.
