Yeah, but you can also go find a working NES. Also, there are usually a bunch of classic games released on the new consoles for relatively cheap. Xbox live, for example, has a ton of old school games available, and most are no more than a few bucks for the full version.
I'm not trying to sound like a console fanboi, obviously the PC has more capabilities when it comes to modding and emulators, but both consoles and PC's have issues with older technology.
