Even so, a large portion of that is still theft. A big percentage of the NES, SNES and N64 libraries are going to become profitable items again, due to the download features of the Revolution. That's theft of sales, and there's no reasonable excuse for it.
Most people don't have problems with that. It's just as if they are downloading media illegally through programs like Limewire or Kazaa. I just think that the PSP is more a computer than a gaming device.
