i looked at a website called evil-psp.com and they give you a firmware that can download the game from a umd. so what you could do is go to blockbuster rent a couple of games and download all of them to you psp and play the game without the disc.

demonoid.com.but first get familiar with torrents and download utorrent from utorrent.com.the registrations for demonoid are available only on weekends but its worth the wait

psp download center.com they give u a bunch of demos and some from japan

dont download games. yes its possible but then you ruin the chances of making new games in the future. then psp will just be crap.
check out psp-hacks.com
this is why the dont really come out with umd movies. please support psp. not kill it.
