He's walking faster because it's inputting his step programming faster than what Ed intended. A human just can't hit the pad as fast or consistently. No way to ban it online, though. Only way to ban it is in tournaments. I wish programmers would restrict turbo inputs. The programmed dpad is just not fair, but other people are going to use it, so I figured I'd warn people ahead of time. Not ban the pad, just the function, which is already banned under turbo abilities.
What's funny is that a guy on srk is saying the pad sucks for qcf, but it doesn't suck. It's a stiff dpad, but it works just fine. Time will tell if it holds up, but it's one of the best pads I've ever used. It's a favorite of mine.
