This is a pretty major update but it's is a pseudo beta.

The new CRT filter does far more than just make the game look better now.

Using retroarch and the windowcast core it now changes the way the image is processed and eliminates the inherent input lag the game once had.

This is a bit complex so I will explain.

First you must install Windows Power Toys.

Then you open up Metal Gear Solid Master Collection.

Next open up retroarch.

Load Core should be the first option.

Chose Windowcast.

Once it's loaded, choose load content.

Load the file partials-example.txt

Now you should be in game.

Now hold Ctrl+windows and hit T.

Now Tab back to the master collection and the game will look very dark.

Now hit L3+R3 to bring up the retroarch menu.

Select the core from the recents list.

When you open up the cores options scroll to the bottom where the shaders menu is.

Hit load shaders.

Scroll all the way to the bottom of the list and load "final.slangp"

Once all of this is done, you will have a CRT shader loaded with black frame insertion that will eliminate the input lag.

Yes this process is complex but this core is a beta and I will be working on eventually simplifying it. However, as of right now it is the best way to play it hands down.

Please keep in mind this was tested on 4k HDR at 120hz.

If you are having issues on different displays please report it.

The input lag has been plaguing the game for a long time now and this is the only way I've found that actually gets rid of the problem for good and you don't have to settle for all the screen tearing from the Konami option anymore and the game now looks fantastic.

The problem is it's so realistic I can't even use the screenshot option so I attached some taken with my iPhone.

That being said the images really don't do it justice!

One other note, you may have to adjust your brightness level for the filter. It's just the nature of how it works.

Major shout out to Nuggs for doing the heaving lifting on the scaling issues and adding the analog injection! MGSM2Fix
Another shout out to Spoopytoots for the steam config!
And yet another shout out to Smash45 for helping me with the AMD profile!

I made the CRT filter and the Nvidia profile which makes the game look good and stabilizes the framerate.
Just be aware that if you don't install this to the default location it will break the CRT shader and then you will have to manually adjust the reshade.ini to point the shader to the right directory.
Fixed the issue with the shader not loading. Also added full analog controller support.

IMPORTANT NOTE!!!
Analog support requires this steam controller configuration: steam://controllerconfig/2131630/3087945618

***Instructions***
Each file now has a separate folder due to Vortex compatibility Shout out to Afevis for arranging that!

Install the controller profile listed above.

For Nvidia:
Install the Nvidia profile that is provided with Nvidia Profile Inspector

NOTE: If you receive the error message "Some profile(s) could not be imported!" then make sure to remove your old profile for the game and replace it with this new one.

For AMD:
Unfortunately AMD doesn't support profiles for individual games so you will have to manually set them.
Set Vsync to always on
Radeon Chill to 60 FPS
Tessellation to 16x 

Done.

If the menu screen looks weird and the text is misaligned, congrats it's doing exactly what it's supposed to and will  look great in-game!

Now the game will auto boot to borderless full screen and default to whatever your desktop resolution is and you can use the letter "O" key to turn the CRT filter on and off.

Unless you are on Steam of course in which case you will have to install the shaders manually.

Enjoy =)
*Next on the list of maybes but not sure yet: upscaling, 16:9, Overclocking*
