Whatever you do don't go looking for a ps3 or 4 emulator for at least another 10 years.
I once tried to get a 3ds emulator so I could play pokemon, I regret it because it killed my HDD because of all the shit. None of those things work. Best you've got is some old time N64/Gamecube/PSP emu's that work.
I believe there was an emulator seeing early stages of success but no where near the level required for a game like The Last of Us. Besides, emulation requires heavy processing power on top of the game itself, it would be difficult to run on today's systems at a respectable frame rate.
