How to remove the Bilinear filter
By samuskay
A guide on how to remove the Bilinear filter that you can't disable normally to make the game extra sharp.

Will probably help with things like reshade as well.

I did not make this fix and am just making a guide to make it easier for others to troubleshoot.
update 2
A mod that is starting to cover all the bases is .
If the link is removed its the MGSM2Fix and its linked on the pcgamingwiki page for this game if needed.

I'd recommend you use this instead as its more user friendly and doesn't require changing files :).

Thanks for your interest in my and others work in the mean time.
Update: New script

Still in the testing phase but it should be much more straight foward.

option 1 will find your game location through the registry and patch the game for you as well as backup the original files.

Option 2 is in any case where option 1 is unable to find the correct path, it will require you to copy the files to the patch folder, run the script, then move them back.

Let me know of any issues you come across with this.
Video guide
The github link for the fix is here:

The file this guide is built off and also another fix someone else made are here:

The delta patcher seems like a great method but will only work on US versions of the game right now, so if the ntsc version of mgs1 is what your game came with without downloading any dlc then give that method a shot.
github patch guide
Go to the github link and then click code then download zip.
(if you have any issues with this guide you can also try the version from the time this guide was made which will be in the google drive link)

extract the zip folder using what ever program you'd like. you should end up with a folder with all the stuff in it.

go to your steam, right click on metal gear solid master collection version, click manage, browse local files.

From here go to the windata folder (ignore all the crossed out stuff that was me experimenting with possible methods before this one)

Backup alldata.bin and alldata.psb.m.
I personally back these up to the folder with the patch in it but its up to you.

now go to
And download the runtime installer x64 (if you're on a 32bit version of windows download the x86 version instead) and run it.

now go back to that patch folder we extracted earlier and run the patch.bat file.
Then drag and drop the alldata.bin from your mgs1 game folder into the window.

(if when pasting the line you get quote marks on either side like this, manually delete them as they tend to break the script).

After drag and dropping the file (and getting rid of any " marks) just click on the window and hit enter.
You'll know its working if the following happens:
A window pops up to unpack the files

A file is successfully copied
and a window opens again to pack the files back up.

once this message pops up you should be done, check if your game starts successfully, then you should see more of a staircase affect on the M on menu.

If the second window never pops up or you're asked if its a file or a directory then make sure there are no quote marks in your path and that you have installed dotnet 2.2.0.

If the file fails to copy try using the version of this patch backed up in the google drive.

If once completed the game is just a black screen then restore those 2 files you backed up and try again (if you didn't back them up thats ok, you can delete them and then on steam verify the game in properties and it will download only those files again)
Delta patcher (easier but only seems to work on North American version at the moment)
Download delta patcher version from google drive.

as in the previous guide back up alldata.bin and alldata.psp.m.

Open up the delta patcher and click the folder icon next to "original file"to select the alldata.bin and then click the file icon next to "xdelta patch:" and select "mgs1 filter disable (for alldata.bin.xdelta".
Do the same for the alldata.psp.m and you should be done.

When I ran the delta patcher I get this error "An error has occurred: xdelta3: target window checksum mismatch: XD3_INVALID_INPUT" Any ideas?
samuskay  [author] Nov 4, 2023 @ 4:15pm 
@EVERGREEN yeah so if theres no window that means its not actually doing it, the script doesn't account for that failing sadly.

I'm guessing you installed the game and moved it? the script can only see where the game was originally installed sadly, doing otherwise would be more complicated.

But thats what script 2 is for and i'm glad it worked for you :).

@Samuskay alright, i got it to work! I was using the new script, but the automatic method did not work. Basically, it would say that it found the data and patched the files, it created backups too - but the games were still using billinear.
I tried method 2, and I'm 100% positive it did work the first time around!

FYI: the games are installed on my D drive, and I ran the script from my F drive. It did detect the filepath correctly, backups were created, and the output terminal said that patching was done. However, contrary to method 2 there was no window about the packing/unpacking process.
It's most likely an niche issue with filepath or something, method 2 did the trick though and I want to thank again for that. It looks sooo much better!

@gliv not at all that i'm aware of. they still unlock fine for me
samuskay  [author] Nov 4, 2023 @ 6:18am 
@EVERGREEN make sure you're using the new script I link in the (update: New script) section. I've tested it on the new update and its working for me at least.

When you run it is it extracting files, copying a file successfully, then packing it back up?
EVERGREEN Nov 4, 2023 @ 4:58am 
@Samuskay thanks for the answer. The last update may have broke it indeed, as it seems like the patching process did work (Folder is detected, backup created, alldata.bin is modified judging by its last access date) but billinear filtering is still here.

Does this break steam achievements at all?
samuskay  [author] Nov 3, 2023 @ 7:54pm 
@EVERGREEN the new script at the top should work for all versions.

I personally have an EU version as well and thats what I tested with.

The delta patcher only worked on the NA version and not sure if it works after the update.
EVERGREEN Nov 3, 2023 @ 12:28pm 
Hey there, thanks for this but I can't get it to work. I'm the EU, so the default version is the PAL one. However, I play the NTSCU version. Is there a way to make this work with the DLC NTSC-U version (or any other one for that matter)?
