I just find it hard to believe no emulators or filters implement oversampling. It's not exactly hard, and its been used in the audio realm for over 30 years at least. In this world of digital flat panel displays stuck at one resolution, it makes it even harder to believe. At least IMO; which is why I ask .
Here's an example of why oversampling is just so much needed it's not even funny. I'm going to use a homebrew game of Sonic for the SNES.
original 256x224 size
if you upscale to say, a native 1280x1024 size, you get this on a typical DFP:
Does that look bad to you? To me it obviously looks nothing how the original looked. It's been turned into a muddy-blurry look after being upscaled with typical bilinear filtering. This is what happens on most digital displays.
Watch what happens when you apply 5X oversampling (which is hardly oversampling for 256x224 to 1280x1024):
That looks way better doesn't it? I didn't even use bicubic or lanczos filtering; it was mere linear filtering.
Even if you stretch it to a distorted widescreen 1280x800 resolution, it still looks really good IMO (besides being fat haha).
That doesn't even consider what happens when you add scanlines and other filters. Scanlines get really distorted lots of times, until you use filtering; but then you end up with blurry quality that looks nothing like a good display (IMO).
Would anyone even care to have oversampling?
