From the website FAQ:
"
Are tool-assisted speedruns fake?
Fake means something that is not what it is claimed to be. A glass jewel could be a fake diamond.
The makers of tool-assisted speedruns do not claim the movies to be recordings of real-time playing ― thus they are not fake.
Are tool-assisted speedruns cheated?
Cheating has two meanings:
To deceive by trickery.
To violate rules deliberately.
Arguably, we do cheat the games. The games have been programmed assuming that the player is a human who has humanly limits. We surpass those limits with tool-assistance.
For example, there are very few humans who can produce a 30 Hz autofire by rapidly bashing the B button, but in tool-assistance, it's trivial to do that.
We also abuse many programming errors in the games.
But we don't cheat the audience. The makers of tool-assisted speedruns are very open at how they've made the movies. There certainly is no deceiving taking part. (We can't help people who just don't read.)"
It was still a good watch!
