Yeah Graham, if you don't get it we could still spar in HD remix. I tried doing the fireball at all speeds no luck.
Jason, from your achievements you beat the game on hard and also beat it without continuing. That's pretty good skills IMO.
badgenome, I want to add you to my friends list, we could play sometime.

Okay everyone, I kind of figured it it. You have to cancel the high kick animation by doing a focus attack dash cancel. You do the high kick, focus attack, dash quickly to cancel the focus attack and then do the fireball.
I still can't get it though, but I know the FADC is the way to go because it worked on a similar challenge with Chun Li.
It's just funny to me they consider this "normal" challenge but I doubt 5 percent of players would do it easily. Plus NO WHERE does it tell you any of this, you are just expected to know it. I couldn't find it on the book. I finally found it on a post online. I think I'll give up on those types of challenges though they are too frustrating, there's too much fun to still be had to bellyache over that crap.
