ok ive been in the homebrew scene for a while now but i sold my psp 1.5 for 300 and i bought a wii, sonow with me having practice and all and always being on the road i wanna buy another 1. My little brother has a perfect condition psp (wit screen protector) but the downfall is its firmware 3.30, which sucks, so is there a way i can downgrade, and ill use it for homebrew, but ill mostly use it for multimedia so should i jus leave it the way it is, cuz 1.5 doesnt play wma, and crap like that, so can i emulate a higher firmware and then use all my music and stuff, plus have homebrew???

thanks in advance!!!
