Aglar's Sonic the Hedgehog 2 TAS in 17:51.6
***READ BEFORE WATCHING***
This tool-assisted speedrun by Aglar aims to beat Sonic the Hedgehog 2 as fast as possible.
The author's comments on the run can be found here: http://tasvideos.org/3557S.html
It was made on an emulator, using frame-by-frame shooting, savestates, and rerecords to overcome things like reaction time and human error. As such, it is purely a form of entertainment, and is not designed to show skill.

Any anti-TAS comments will be deleted. Seriously, if you're just going to call it "cheating" or something equally ridiculous, don't even bother commenting at all, because I'll just block you. Save us both a bit of time.
