darthspudius: Seems to be working fine without any mods.

bobdotexe: hmm, what os are you running? I think it may work better on windows 7 vs windows 10.

But regardless, I'm glad to hear it's working for some people

bobdotexe: Yes, the GOG release is a re-release of the old discs, So it really needs some work.
Here's what I'd recommend:
'Metal Gear Solid 1 Integral PC [1080p/Xinput Controller Support/DX10.1]' (check /r/metalgearsolid)

I Not sure if I'm allowed to link it here, it's a full reverse engineered project that I'm sure contains copyrighted assets.
The main advantage to switching to directX10, is the better support for modern OS's.
But the project also fixes a lot of bugs, and adds significantly better controller support.

This is the Final Release, and it's marked as 'stable'
------------------
Latest changelog: (V0.02 -> Final)

-various minor compatibility fixes
-updates source renderer/HW API
-various minor fine tuning renderer parameters
-GPU HW/Software emulation fixes related to scale/aspect ratio
---------------------------
Note to the Moderators:

This is not a Cr@ck or W@rez!
As far as I can tell, this is a Clean-room reverse engineering project, made by fans, and offered for free without even optional donations.
Konami reserves the right to remove this project, but they have not done so in the 4+years since it's completion
