You can easily emulate them all these days. I know it's not the same, but often times, that's actually a good thing. It's far less of a hassle to play older titles on modern devices than to hook up an analog output era console to a modern TV and getting a good image quality out of the combination. Not to mention, performance and resolution were often much worse than you remember. Hell, some emulators even fix bugs and you can easily play ROM hacks or other mods that way - which sometimes also fix bugs, like a fan-patched version of Gran Turismo 2, which makes it actually possible to complete the game.
