mod your psp and get xmb editor
The psp goes through a firmware and then a software mod to make it what they call "modded" I personaly have heard of no battery mods besides the LED's and other cosmetic changes, In other words no hardware change, just software. Also please not that there are several different versions of the PSP out there now and not all of them have the same capabilities.
If your talking about the psp 3000 aka psp bright, there's no offical firmware mod for it yet. However there is a video of someone who claims to have modded it. See psp-hacks.com for info.
Download what?
Moding the PSP means to make you PSP be able to play games you downloaded from the net.After modding, you can download games from the internet and store the games in your memory card and play the games from the memory card without the need of a UMD disc.There are currently quite a few versions of mod available and it depends on your PSP model which MOD is more suitable for your PSP.
You can update your firmware using wifi in the settings at the top, or better than that you could mod your psp and install ultimate psp tube.
