psp 3000 hacks

i heard that a psp can be hacked to do other things other than play games like download psp games not from the psn store, like from websites that offer free psp games form download. people say a psp 3000 can't be hacked, others say it can be hacked but can't do all the things a hacked psp 1000 or 2000 can. I'm getting a psp 3000 from a pawn shop and want to know can a psp 3000 be hacked?. and if so, can it do all the things a hacked psp 1000 or 2000 can. I NEED TO KNOW THIS BEFORE 4:00 BECAUSE THAT'S WHEN I'M GOING TO GET IT. i mainly wanna hack a psp 3000 to play nes,genesis,n64,snes,ect emulators and play psx(ps1) iso's
