The version of Gouken used in the video is edited by ShinySpiritSeer.
This is what he said,
"""
Just a bit of an AI edit I'm working on as well as a Boss Mode!
AI and Boss Mode are designed for Normal style only, not EX mode!
Is not designed for ground or air chains!
-------
WHAT's NEW?
-12th Color "Shin" Mode added! Loosely based off SF4 Boss Gouken!
-AI adjusted to be more smart with choosing options! (Applies to Boss Mode too!)

The only thing I missed is Benhazard's sprites.
