Best way to upscale 240p contents to 4k resolution?

Hello! 
I posted the AviSynth scripts used for each video on YouTube in the comment section.
I know, I cooked lots of strange things!
But I tried each time to get the right visual alchemy.
The problem is that I tried to upscale 480p contents in parallel with all these methods adapted, but sometimes it was good with 240p resolution and not with 480p, other times it was the opposite.
My goal was to have something which is good with all contents, but it's complicated.

I was going on a new thing, it was very great with 480p contents, but a bit artificial and unatural with pixel art contents.
And then, I compare with the script of the Method n° 7, and I think it's great!
You have chosen the Method n° 7, so I think I will keep it
(the only problem with this method is that there is more ringing)
Thank you very much everybody for your votes!

Oups! In fact... I just noticed that it wasn't for Method n°7 that people voted, but for "It's better to try something else"
But it would be great if somebody could propose something with pictures...
I'm sure that some people are better than me for this kind of things.

Just does images right now, but is pretty incredible.

Ai will definitely be how this stuff is handled in the near future.

In fact, as I said above, my first goal is to have something great with 480p contents, but ideally it would be great if it could be great with 240p contents to.
With 3D cinematics, it's not really a problem, but with pixel art games it is, because the aspect was so linked to the CRT technology and in the other hand we are today so used to the raw aspect too with the modern pixel art games, that it's a bit complicated to find the right balance.
I wanted something which is great with everything, but maybe it's impossible...
So I focused one last time exclusively on what I want for 480p... and I think it's great!
With 480p it's great... with 240p contents, I need your opinions
Thank you very much!
With cinematics, I think it's good!
With Super Nes games, I have a doubt... Except for Super Castlevania IV ! I think it's super great with this one!

Thanks!
There is just one problem with the Nnedi3 filter that I used (watch where I put the red circles) :
As you can see, it creates some kind of seperations between pixels, whereas it should be like that:
Maybe it is only a little drawback, I don't know, but as usual, it's not perfect!
But otherwise, I like the image with my script (I wrote it in the comment section of my last video)!
Nothing amazing with the script, but as always, I just tried to cook something that could be satisfying visually
But yes, I understand your problem! It's hard to find the perfect method!
Even with AI upscaling it isn't perfect.
I tried so many things too. Nothing works like the CRT screens did with digital images.

Get a Bravia TV and let it upscale plus play every game at 60 fps

It's to do videos, not for playing

But as I said:
And I don't have my Super Nintendo anymore. Yes, I know... shame!
But it was a PAL version, so not so great...
But I agree. A Framemeister looks great with original consoles!
The OSSC and the RetroTINK 5x too.

Some people will like this I think!
I wanted to try another CRT shader with AviSynth, but just for the fun, because for videos, I will definitely not use them. The effect is too variable when the image is downscaled or upscaled.
But just to for playing or with still images, it's great!
You can find the plugin for AviSynth here: https://forum.doom9.org/showthread.php?t=170732
I tried :
Click on the spoilers to see the picture!
As you can see, with still image, it's great... but for videos, as I said, I think it would be problematic
The biggest issues are the loss of brightness and the moiré effect when the pictures are downscaled.
It's the main reason why I don't use CRT filters for videos.
For a perfect effect, the scale of the image has to be 1:1.

I tried :
- Cromaclear display type
- Aperture grille display type
- Simple scanlines without phosphor effect

I found the sweet spot! For me...
I did my tests with some Tomb Raider 1 et 2 videos. I compared with videos of these 2 games on CRT TVs on YouTube.
My goal was always to have a consistent image, focused on the representation, not the pixels.
We are too focused on the pixels nowadays.
Finished... this time!

Hi!
I had a relapse...
In fact, the pursuit for perfection is an never-ending story
I did a new video. I'm close to what I'm looking for.
It's like I could see what I want, but there is always a little something that I can't achieve
It's frustrating...!
