A new skip was recently found by @Kapdap which allows you to skip the first 23 seconds on Dulles Airport where you walk around and do nothing.
At the very beginning if you're quick you may see this box on the floor by the front door 
Shoot this box several times to destroy it and you should see this message:
This then immediately takes you to the side of the airport where you the enemies start attacking you.
Again this is can be a finicky one to get as you really have to be quick, but it saves a ton of time and is 100% worth it.
Hey all!
Just a quick update to say that @kapdap has kindly made some atuosplit tools for each game for people to use with their EMU runs to give everyone the most accurate timers possible.
For those new to using auto splits with Livesplit here's a video I found that should help get you started -
