PSP on the Comp?

Im pretty new to the forums and i was looking around but i was wondering if there was any way to view the psp game/movie on the comp while you play it or watch it? Its kind of a long shot but i didnt know if there was some software that allowed me to view the psp screen on my desktop. I run a projector through my tower and i can play movies or games on the wall in my room and i think it would be awesome to be able to play homebrew snes or nes on a 100' screen while sitting on the couch. I just thought it would be a neat idea to do this, as it is now i jus use the projector to play WoW or watch movies but i would rather play Super Mario 3 on the couch heh.
