Funny that everyone else thought in the beggining that this couldn't be done on a cabinet, I thought it was some emulator cheat shit but then I saw it on xbx 360 and a friend of mine try it out and told me. For me it's easier to do backx2 and a small, quarter circle back-up, like when you do Sagat's tiger knee on SSF2, but obviously backwards
a tutorial video would be useful for a lot of people, go for it
