The UI on the left isn’t labeled, so it’s hard to tell what any joke could be if you don’t know what it is
I’m sure there were other consoles that did it, but the one I remember is the NES; it had a physical switch on it for channel 3 or 4, and you had to have your TV tuned to the respective channel to get the game to show up. As to why that was necessary on a technical level, I’m not sure. But it was a thing you had to do.
This is how I approach these: that square only has a single traffic light, not multiple traffic lights like the prompt is asking for
