Low-level firmware typically resides in a PLA structure or in a ROM (or OTP/PROM), while higher level firmware (often on the border to software) typically employs flash memory to allow for updates, at least in modern devices.
you can get alot of games for psp from gamestop or download custom firmwire
perhaps your psp has a lower firmwire version.
Yes, but I believe it requires you hacking ur psp firmwire.
non volatile ROM
Yes, you can. A game ROM is a copy of the original game, so all glitches and cheats works on ROMs. See the related question if you want to know how to get it.
jailbreakme.com on your safari. 4.0 or lower firmwire veresion, no higher. search on youtube for more info.
Im not quite sure, but from what ive heard there are mixed reviews. Some say that you cant downgrade a 3.90 firmwire. Some say that you can downgrade any firmwire with a pandora's battery. Its quite confusing to me. I havent do it because im not sure what will happen. I, too, have a 3.90 firmwire. I dont want to waste a perfectly good battery trying to make a pandora's that might not even work. But i am getting closer to my answer. Im still leaning toward making the magic memory stick and pandora's battery. Ive read so many instructions on how to do it I can make my own forum and tell people how to do it.

A CD ROM drive cannot read a DVD. So it is not possible to use a CD ROM as a DVD ROM. A DVD ROM drive can work with a CD though.
