I tried looking on archive.org and all I got was the bonus disc. Which one is the executable, and which one doesn't have viruses attached to it?

What would be the load time differences if the HDD is used instead of disc?

Are these codes allowed for speedrunning? Because the seven second loop of the invincibility theme gets really tiring after a while.

Is it viable for running? Or does it have any differences that might make it a disappointment to run?

Do you just mute the entire livefeed's audio for said mission or turn the in game volume all the way down? Because copyright is strict with Phil Collins songs.
