CONFIRMED, arcade possible!
Finally got around to making this... Hope it helps! = )
Standard double Fukiage
Double Fukiage with another double Fukiage as the ender
Second chance stun combo
Depends on the screen shifting before the Fierce->Fwd Super. If it shifts, you MUST bounce Chun-Li to the left, if it doesn't, you must bounce her to the right.
If you use RH for your Super strength... When starting from the right, bounce Chun to the right... When starting from the left, you need to delay your dash...
From the corner!
Max range stun combo from the left side
This first one is the easier version, basically you just slightly delay the dash, then delay the Fukiage and have Chun bounce to the right, the Fukiage timing is the same as the second chance WFukiage I posted earlier.
This one is only recommended if your screen positioning prevents ^ from being possible...
Delay the dash more, hit the first Fukiage so that Chun bounces left, now WALK left a few pixels and hit the fastest Kara Fukiage you can. The timing is far more strict then any other normal version. So the inputs after the first Fukiage would be (
+Jab. (If you delay the dash until you are off screen, you don't need to walk between the Fukiages, you can see that in the main tutorial video.)
Yet another way of landing a double Fukiage on Chun-li........This time with 2 dashes!
I knew this way had to be possible... Only for show, it's so random that you'd even be in this position... Plus, from where you start this, you can do the cornered double Fukiage starting with Forward SA2 instead.
Barely outside of the corner, Short SA2-> immediate dash-> Kara Short--~Jab Fukiage-> dash, cr.RH~Jab Fukiage.
^this^ was easily my most attempted technique/version before finding the other ways.
The timing is stricter while cornered so it's easier midscreen IMO, I've only played Pad so you might think it's easy.
I have a stick now and it's much easier to do!
Midscreen: Walk back after SA2, as in 6236(hold)+jab, Kara Jab Fukiage with st. Short.
(You can stay still before the Fukiage midscreen, the important part is delaying it the proper amount)
Cornered: Try to stay fairly still after SA2, delay the Fukiage longer than you would for the midscreen combo, this juggles Chun away from the corner, similar to how the Stun combo works on Oro for example. Note: you can do it where Chun juggles towards the corner, but you have to walk in the opposite direction... 6234(hold)+Jab, which is much more difficult.
1st tip: After the first Fukiage, don't move or press a button, when Chun wakes up st. Fierce her, if it connects or is blocked (or you're within a couple of pixels of hitting), you're in a good range for the 2nd fukiage, so.. if it barely whiffs when you're on the left, you hit it too early. If it whiffs by a good chuck when you're on the right, you mistimed it (under normal circumstances, the Fierce never connect when Chun lands on the left)
2nd tip: EDIT: No longer needed, it was basically useless.
These are uploaded to the 360 match server aswell (for those interested in seeing them in good quality, search "telesniper" under tags on the replay options, you'll need to scroll down a bit), the only DIP switch change is starting with max meter.
Since finding this about a week ago, I've landed it more times than then I have the double kara against Ibuki and Oro, so I'm very much looking forward to seeing this in some high level play.
Also, I didn't know if I should put this under a Makoto thread or not... Figured since this combo was only a rumor for so long it merited it's own thread.
