Still have my Nes, atari 2600, colecovision and intellivision. Hooked up in my games room to a 19" crt tv. So I can play duck hunt and hogans alley with the lightgun. Have a good collection of clasdic game carts.
I also have them emulated and play on my living room 56" tv. With a lightguns as well for arcade shooters and nes shooters. Use wireless xbox 360 controllers for all other games.
But still turn them on in the game room every pinball night with friends.
