This had to have been faked somehow! Insane!

Holy Shit! That was insane! That was awesome! Good find Mike!

Forget Ico and Flower -- this is art.

There are run-through helpers you can use to do things like this. It constantly checkpoints your emulator position and if you mess up you can back up. Or another approach is macro-ing the whole thing: at time x, hit this button, at time y, hit this button, etc. etc. Either is still painstaking, but not quite as mind-boggling as the idea that someone actually did this without dying.

Tool-assisted, for sure. A program would take a string of controller commands and issue them into an emulator at precisely the right time.

It's still artistic in the sense that the author designed this ridiculous level *and the sequence of commands* that would traverse it.

I love it when the respective hacking and tool-assisted speedrun communities come together like this.  I mean, they generally go hand-in-hand anyway, but this makes it really apparent.  Kudos!

I think I may have had a small seizure watching that.

*Dumbfounded*

Emm...errr...uhmm...eh...what just happened? That was ridiculous, even for a tool-assisted emulated level. I have no more words to describe my feelings.

Gonna go with save states and slow motion.

I must have said "what the F!" a hundred times watching this. Impossible, especially the last 20 seconds.
