Hello buddies
I come back to you, because I thought about one thing... an important thing !
As some of you know, Higan is the perpect emulator, close to the original experience of the Super Nes, but on the modern display
But I asked myself, how they did to reproduce the original colors, which are darker. Is it simply a way to imitate the feeling of the old CRT display ? I think yes and no... maybe !
I thought one thing : my pictures are in RGB 24 bits, so the levels are 0-255.
But at the time of the CRT display, maybe it was meant to be display in a equivalent of RGB 16-235.
No ?
I tried this, and in fact, my image was close to the image of Higan, even if not exactly (maybe the gamma).
After some other researches, I read that the gamma of the CRT was close to 2.5 too if we compare to the gamma of 2,22 on a modern display.
So I convert the gamma of the image too
Actually :
1 / 0,45 = 2,2222222222222222222222222222222
So I calculated :
2,5 / (1 / 0,45) = 1,125
So, I used this function to transform my gamma and my levels :
And really, it's closer of what I remember of my experience on a CRT display !
Just for the example, the picture of Mr. Nutz with the spider, I remember how it was dark on my CRT screen when I was a child. It really was a dark atmosphere, the moon was very present, like almost the only comforting glow...
By the way, I was always surprised to see that it's so clear on my LCDs with an emulator
As you will see, it's not so bad... I hope !
I change this too :
nnedi3_rpow2(rfactor=2, nsize=0, nns=2, qual=1, etype=0, pscrn=
3, threads=0, opt=0, fapprox=0)
With "pscrn=3" instead of 4, I noticed that it's closer that what I remember. And yes, I can see the difference !
I compare in zooming with the original picture of Killer Instinct and a the picture of the same game in a video of the Super NT (a real Super Nintendo HD, not an emulator), and it's closer now !
With "pscrn=2" and "pscrn=4", there was something weird. It didn't perfectly match !
