I searched for any mention of this and couldn’t find it. Don’t know if this is old or not, and I’m assuming it “works” for every character, but only tested so far with Makoto vs. Urien in parry training on PS2.
Anyway, I set Urien to do an Aegis as soon as the round began, and buffered the motion before the actual round started. I was holding up-forward with Makoto at the start and before the super freeze she entered into what was probably the first frame of her jump (where she kind of ducks down before she leaps) and was in that frame during the black screen. Well, during the black screen, I started holding up-back, and instead of jumping forward (the input before the black screen), she jumps backwards. It seems that if you’ve entered your jump frame before the black screen and were frozen there, but not yet actually jumped, you can change the direction - assuming the first frames or so of the jump before leaving the ground are the same forward and back.
Probably not useful but odd enough I thought I’d share.
