So I run some tests, I grabbed an old shot as reference, then the new preset with grade, and following the fix (color adjustments) I did just now.
What I did mostly was lower saturation, lower gain, enable hotspot fix and lower white-green. I also added some green to reds to remove that blown pure red. As usual I also add green to blues, this makes skies look better (Azure blue), or Sonic color more natural.
This is something I would think ntsc emulation would suffix but it doesn’t, so there’s something else going on. I tried using the Triniton LUT but it’s not working fine on all systems and I don’t know why. It’s the “Sony Trinitron Std D50 - Edit 1 - Gamma Unadjusted -32px”. I interpret that as a linear 32 points LUT, it changes the white point to D50 (from D65) I guess.
