The guy who wrote the scanlines demystified article we mentioned way back has a new article up, investigating deinterlacing solutions for old consoles on new TVs. This was particularly of interest to me, as my PC Engine looks absolutely terrible on my LCD television, with artifacts galore. You can view his article here. He doesn’t come up with the definitive answer, but he does evaluate a whole lot of upscan converters for you, so it goes a way toward helping in research. For what it’s worth, I’ve been told the best solution is simply to get an HD CRT television, but that doesn’t help get the maximal signal, even still.
