i have psp snd it a whole lot betterr then the ds. with the psp, depnding on what version it is, i can play homebrew games on it right from my memorysick. i can also dl games (iso) and save it to my ms, i dn't have to buy a game ever again. The graphics are brilliant, and yes you can play with your charger connected. there are loads of things you can do with it. you can also use your psp as a remote if you want. very handy when your just stoned and can't be bothred looking for the remote.

i had a firmware 2.5- but then i downgraded to 1.5, so i can play homebrew games and dl games for it.

hope this helps:rasta:
