NES Gradius in 14:12.0 by Morimoto

http://tasvideos.org/19M.html

This is a tool-assisted speedrun, made on an emulator, using frame-by-frame shooting, savestates, and rerecords to overcome reaction time and human error. As such, it is purely a form of entertainment, and is not designed to show skill.

Morimoto picks only "Speed" upgrades and has fun with perfect reflexes. That's certainly something nice to do, because the game scrolls automatically and the player can't affect the speed.
