You can AC the 44AA with some timing, you have to wait for the second A to stopped tracking (it does this shortly after it starts up) then ACing (from 1P side) 1_7 or 9(harder). Additionally you can AC the 66B by by holding 1_7, no timing required.
I don't think this is a topic that warrants its own thread, posting something like this in some general Q&A or combo thread would be better.
