Ohhhhh!! Thanks for solving the mystery for me. I'm curious what the origin of this is.. Did anime fighting game cabinets use numpads?IIRC, it's mostly numpad notations.
236 is traditional Quarter Circle Forward (QCF) and so forth, D is probably Dust, (P)unch, (K)ick, (S)lash, (HS) Heavy Slash.
J jump, JC (jump cancel?)
