Piracy has raised the PSP's hardware sales considerably, as there is no easy alternative to owning the hardware for playing the software available for it. That's about all it's done, however. I suspect that, without the ability to pirate, PSP hardware sales would be roughly 50% of what they are because of it. Certainly the pirated-to-software-sold ratio suggests as much.
Sky Render - Sanity is for the weak.
