Here's how to fix METAL GEAR SOLID 2 and 3 on Steam Deck / Linux

By - | Views: 46,535

Update 26/10/23 15:54 UTC: Valve developer Pierre-Loup Griffais mentioned on X that Proton Hotfix was updated to help but it's still not fully solved yet without the fix in the guide below:

A Proton Hotfix has been deployed for "METAL GEAR SOLID 2: Sons of Liberty - Master Collection Version" and "METAL GEAR SOLID 3: Snake Eater - Master Collection Version" to address a blocking crash in cutscenes. A fix for missing audio in cutscenes is still being worked on.

For the impatient, it turns out there is a way to make METAL GEAR SOLID 2: Sons of Liberty - Master Collection Version and METAL GEAR SOLID 3: Snake Eater - Master Collection Version actually work on Steam Deck and desktop Linux since they're currently broken.

The best way would be to wait for Valve to roll out an official fix in Proton, but if you really can't wait the fix is relatively simple. Thanks to sleuths on the GitHub bug report you just need to get a copy of xaudio2_9.dll either from a Windows install, a different game or other methods like this website (use at your own risk, and get the 64bit version).

For Steam Deck, you'll need to be in Desktop mode (Steam Button -> Power - Switch to Desktop). If you downloaded it, make sure to unzip / extract the file, then in Steam on MGS 2 and MGS 3 right click -> properties -> installed files -> browse to open up the file manager. Then place the xaudio2_9.dll inside each to sit next to the main exe files.

After that, on each game set a launch option via right click -> properties and put this in the box on each game:

WINEDLLOVERRIDES=“xaudio2_9=n” %command%

After that, you'll find that they launch, but there's probably other issues but for now at least that will get each game to work. Some issues I saw include:

  • Overblown audio in MGS 3 that sounds distorted.
  • MGS 2 and MGS 3 on desktop Linux run way too fast, you'll need to find a way to cap the FPS. You can use Gamescope for this to cap the FPS to make them run normally like so:
    WINEDLLOVERRIDES=“xaudio2_9=n” gamescope -r 60 -- %command%

Here's a video doing it on Steam Deck:

If the scam is a scam but it also doesn't work, but you can fix the scam so it works, is it still a scam? Yes.

Concerning MGS2, yesterday I tried to restore my copy from GOG (+ the fixes) on Lutris, but it looks like winetricks has again that certificates issue and throws the Error 256 again. I have to archive it with all the dependencies already installed next time.
If it could work, I wouln't see why I should buy also the Steam release.

Linux or not, from everything I've seen so far it's a far better experience to just emulate all of them. I even read that the first game is just wrapped in an emulator? A shame, I'd gladly buy old games like these fixed up to run on modern machines if they spent a tiny bit of effort to make sure they, well, ran.

It's the same for me, and I've done so numerous times (usually it's with emulator-wrapped collections, and I'm fine with that - I know it's generally the most cost-effective way of keeping old titles out there). I've been an emulation enthusiast ever since Sony drew attention to it with their lawsuits in the late 1990s, but I'm always happy to support retro re-releases that keep old games in circulation, as long as 1: they can be made to work on my OS of choice, and 2: they actually work in the first place. This one's having trouble with that at the moment, and I really was hoping to buy it early on.

So really, almost a public service, those lawsuits.

I know other folks who got into it the same way, and it was something that ultimately helped me to find my way here, so I'd say so.

The crazy thing is, that all started back when the first Metal Gear Solid was still current!

Valve is on this faster than the game's own developer. That really is something!

Or, to put it a different way, the game's own developer is on this slower than Valve.
Although really, Valve moved on this pretty quick.

I'm guessing they have eyes on it as it's a pretty big name release and very suited for the Deck audience. Glad they are, not so sure how much faith to have in Konami fixing any of it in general.
