MGS1 has a fan patch too, though I'm not sure it exists in a non-piratey form I can link to. Going by initial reactions for purchasers, yeah, it sounds like you'll still want V's fan fix for MGS2.

It sounds like GOG have added a few touches to make the old PC versions play nicely with modern systems but they're basically the same as they were 20 years ago, which was never a great state on PC. Ratings board listings were spotted for them earlier this week, and now here they are. Metal Gear Solid is now on GOG for £7.19, as is Metal Gear Solid 2 Substance. GOG have dug up the original Metal Gear too. It's not going to be super-great, is it, but I'm game.
The stealth series was clunky but ahead of its time in a lot of ways (and I'm as alarmed as anyone by how prescient their politics now seem) so I'm quite curious to see how the vintage tactical espionage action actually holds up. Solid Snake, Revolver Ocelot, and all their wacky mates return to PC today with re-releases of the first two Metal Gear Solid games popping up on GOG, after years hiding in boxes.
