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

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.
The Deck can’t handle the ps2 games? I can play MGS2 on my Anbernic handheld at full speed except in the rain in the tanker mission, and it is significantly less powerful than the Deck.l, so I’m surprised to hear you say that.
From my testing a few months back, there was significant slow down in the cutscenes. Actual gameplay was fine. I have no idea why. I know that SteamOS 3.5 has a fix for a kernel issue that caused issues with SMT, so perhaps things are better now. Once 3.5 reaches stable I'll test the games out again.
Ahh that makes sense. I was only testing, not actually playing, and the cutscenes were definitely skipped. I bet my handheld struggles even more than the deck there. I have 3 on PSVita, so I never even tried 3, but given it’s much higher quality, I imagine it would struggle greatly.
The Vita version is flawless, I guess because it's a native port rather than emulation. Emulation of certain PS2 games can be tricky due to the weird CPU architecture
Mgs3 is a lot heavier than 2 and you probably want the 60fps patch, raising the requirements even further.
Is there a good Vita/3DS emulator?
I'm not sure about Vita, but there is a decent 3DS emulator (Citra). I haven't tested MGS3 on it
