No, your Sega Genesis doesn't and neither does mine. It doesn't even render natively at standard def resolutions.

And 1080 lines of native rendered progressive scan video is still... wait for it...

1080p(rogressive)

No, it's not the same as a 1920x1080 image when it renders as anything but 1920x1080 pixels, but since this has turned into a technical debate over semantics, it's still 1080 lines of progressive scan video.

Don't take my word for it. Do the research yourself.

Personally, I'd be happier if ALL games, regardless of platform would have the native render resolution listed so people wouldn't have to rely on Some Guy with the handle of Quaz51 to let everyone know what the actual resolutions are.

 

 

Yeah but since your definition wether a game is 1080p or not is just the output, all I need is to hook it to an upscaler and boom Sonic 1 1080p, am i rite?

Since all the HD these days is done digital, the old analog scan lines concept isn't used anymore so no, 1080 lines of progresive scan video doesn't qualify as 1080p anymore. You can check the ITU paper on the subject (the ITU being the international organisation that set the standard). Heck, even the SMPTE has abandoned that terminology since it's not forward (not even current...).

Actually if we were to truly dig deep, no game renders at 1080p as per the ITU requirements, since there's a buncha things besides resolution (colorspace and all that jazz). It's the output chip that conforms the framebuffer to the 1080p standard.

Not correct. Displaying a DVD (480 line signal) at 1080p does not equal a native 1080 signal. The native source of the video signal is still 480 lines of resolution, regardless of how you want to upscale it, whether interlaced or progressive scan.

Similarly, displaying a 480 line signal (ie Wii native output) at 1080p mode does not equal a native 1080 signal. Displaying a Wii video signal on a 1080p display that upscales to 1080p does not equal "HD Wii." Nobody said this. Does anyone even think this? The source video signal is still being rendered at 480 lines of resolution which could be either a 4:3 aspect ratio with a horizontal resolution of 640 pixels, or 16:9 at 720. It's still defined as a 480p signal.

A signal being rendered at 1080 lines of resolution and transmitted via "HD" connection is still being rendered at 1080 simultaenously generated lines or rows of pixels, regardless of whether it's 1920x1080, 1440x1080, 1280x1080 or even a 1:1 aspect ratio 1080x1080. Vertical resolution is the definining factor whether you call them lines or rows of pixels.

It is generally assumed that a 1080p signal is 16:9 aspect ratio (1920x1080), but it still refers to the lines of vertical resolution. To say otherwise is the same thing as saying a 480p signal is only a 480p signal if it renders at 720x480, implying a 640x480 signal is "not 480p" which would be completely incorrect. 

All digital displays display in progressive scan mode by definition in that they generate a full field of pixels at once. Even if there are no cathode ray beams that paint scan lines on the back of a phospor coated tube, the terminology is still used by TV broadcast industry, film industry, etc. It's used internationally. So it's not just some hold over definition from the days of analog scan lines.
