Yes, the psp has been permanantly hacked with the introduction of
SIGNED GAMES
you can now get any game online for free, just copy it into the games folder, and
BAM! you got it. You can even sign emulators so you can play any ps1, gameboy, nintendo 64, psp, and some flash games on the psp without any work at all. I wont post any links because that would be illegal, but for example, I just put FF1 on my psp free, today I am gonna get ff6 for it for free.

Sony is completely pissed about this, so do your best to get as many free games as you can. Want one? Google it. In fact, duodecim has already been broken.

What are you waiting for? GO GET ONE!
