Meh, even when it's legal, I never was into the whole "homebrew" scene. At least not with my PSP.
Sorry, but I'm always scared that it's gonna fry whatever I'm modding. It would be pretty cool to make a game, on the other hand. But that's why I pay Ellefanning $6 an hour.
I have to admit, though; while I get most of my music on Amazon/Itunes, I always enjoy getting demo songs from a band's website.
