Can't tell, i can't even get it to work with ralf though, i'm inputing far s.D 3xC qcf.C and get rapid punches that drive cancel into the explody punch. Dunno how this is supposed to be done.
I get it to work with billy though. Easy with him, works off of b.A and d.A. Might have something to do with the speed of the rapid punches, Joe's are really fast after all, they might just be too fast.
