This is the best summary I could come up with:
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:
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.
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).
Then place the xaudio2_9.dll inside each to sit next to the main exe files.
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.
Overblown audio in MGS 3 that sounds distorted.

Steam reviews hate this re-release. Shouldn’t we just be emulating this?

Unfortunately emulation isn’t all that great for these games on Deck. The PS2 versions are laggy. PS3 actually works a lot better than expected, although one of the final scenes in MGS3 has some slowdown. If this version can be fixed, it may be the best option for the deck. I’m definitely not paying the price they’re charging though.
