Our brand new Panasonic TV has an analogue tuner, which autotunes either on initial set up, or later via the various menus. I don't have any analogue consoles anymore so I've never used the option, but I can't see why it wouldn't work. It's just an analogue signal in the old TV range.
Actually, I do still have a Sega Megadrive in the loft somewhere....might give it a try when I'm bored one day.
