I thought a topic would've been made with all the glitches in this game...anyhow, perhaps a few wee minor improvements can be made to the current TAS. Details below, basically pasted from chat, cleaned up...
I have 5 movies I can send to anyone who wants them. These videos are just screw-arounds, but they show off some of the techniques I’m suggesting.
Note that my computer is in a bad state, and its ability to detect input is really something else. I have had to resort to rerecords and countless reboots to make these movies. Some of the screwy detection may be evident in them. Here are what the videos highlight.
Snake’s Getaway 1-3 are all basically the same video, but different runs at it to show off different stuff.

The recording started at the cable car right after Big Boss. I did 3 runs at it to get one with 0 rerecords to show how easy it was with a little practice, to make it back to the train before time ran out. I was going to delete the others, but decided they show some other good stuff.
Snake Warping 1 and 2 start at the end of the final cable car ride, just as the cable car starts to return.

Snake Warping 1 is mostly just another screw-around video. Also note that for fun, if the splash Snake makes is still on the screen when time runs out, he’ll emerge from the water to die again.
Snake Warping 2 is one I’m really proud of. While another screw-around, I ended up capturing many of the glitches by accident that I was simply going to explain here. The powers of warping are quite evident in that one, and that is merely a sample of Snake’s warping abilities. I’d recommend someone with the time and patience try out all the warping moves from all locations to see what other shortcuts might be possible with it. Standing a pixel or 2 in a different spot when a warp is done near a screen edge tends to put Snake in massively different places, so there is a whole lot to be tested here. Furthermore, as you can see, when he ends up near screen edges after a warp, he can make further unusual transitions, or even perform further warps (though I don’t think I got video of any multi-warps).
In addition, if there’s a way to damage Snake, so he can run over the pit and meet the cable car as it arrives, there’ll be a 1-screen jump, so the TAS can be improved if he can quickly accumulate weapons to do this, and still have a net saving in the end after all necessary pre-moves are done, but I don’t know if this will really be doable or not.
Finally, note that when getting warped back to the ship, Snake is unfortunately stuck in the hull. There is no way to get out, and I can’t seem to warp to any other parts of the ship. The boarding walk would have allowed Snake to keep going, either onto the ship (and perhaps to a waiting helicopter again, allowing him to redo much of the game), or head as far back to the jungle as he could. There is no way to keep the boarding walk present to sail the ship, either, as even with the glitch to move about the deck with it attached, you must revisit the screen in order to access the elevator. Unless you guys find another way, this unfortunate event makes it impossible to continue from that point.
