hook up game system to pc hd cheap

[Samnmaxman]

My hdtv only has 1 a/v hookup, 1 component hookup and 2 hdmi, and I have 3 videogame systems. A Sega Genisis(A/V), a ps2(soon to be component), and a Wii(component).So, I'd like to hook up either the wii or the ps2 to my computer the cheapest and easiest way possible - preferrebly without watermarks or bad quality.Can any body help?

well you could get a Switch or whatever they are called and just hook the consoles to that then your tv it would allow you have them all hooked up, im sure u can get them for fairly cheap
