Scriptures on PSP

Hi there, I have a Playstation Portable (PSP) and I see on lds.org you can get the scriptures on handheld devices. However I am not particularly technically competent and cannot work out how to do it. I did manage to save a .txt version of the BoM on my PSP but you really can't use it to read the scriptures as you need to scroll from 1 Nephi through to Moroni - which takes forever.
Anyone know how to help?
Thanks
