Yeah I knew about the emulator crash and that is why I have Integral to try. It seems actually playing the game is fine and no cd pops up. I am going to be skipping every cutscene anyway and we'll see if the grey fox, mantis fight cutscene does it. I'll muck about with the config again and see if I can get rid of it.
Categories I would like to see are the same as theenglishman but also plain Normal mode to compete with the 1:36:16 run by ZENO also on Normal on Jap version. I watched some of his run and it seems the original Japanese game (maybe also Integral) is much easier. One thing caught my eye was his Rex fight. All he does is throw a chaff and stands in the same place for the whole fight and fires stingers. Rex only opens fire near the end with machine gun but that misses him.
I ran his Rex fight next to yours from Boss Rush edition and he was nearly 5 seconds faster. That is his final stinger about to defeat first form.
The second fight he is nearly 6 seconds faster but this time he just lets the missiles from Rex hurt him. So he is approximately 10-11 seconds faster.
My best guess is Japanese Normal is NTSC/PAL Easy mode or something. Obviously your run is on Extreme and Rex will act differently but I still can't see how he can stand there on Normal and do nothing while you need to run around.

It is halfway down the page called "METAL GEAR SOLID -TIME ATTACK- played by PlayStation" and is Scene 8. It is a weird file format and you cannot seek in the video until it is all downloaded. Mines opens up in Windows Media Player then I save it to my desktop when fully downloaded and play in VLC.
