SFxTK had the sf4 unblockables in the first version of the game, they fixed it by making it so you can block forward or backwards during the first few frames of a cross over.
So basicly it went to
frame 1 block backwards
frame 2 block forwards or backwards
frame 3 the cross over actually happens now block the other way.
