You joined a year ago and you’ve never heard about negative edge? what forum are you on?
I’ll give you a tip (For SF3, as I don’t play SF4 because it’s a PoS)
Let’s analyze a simple, but really difficult combo to pull off with Akuma.
a close standing middle kick into his super. If you hit the s.mk, you have an absurd amount of time to hit confirm off of it into the super for big damage. Now, you wouldn’t think that it should be that difficult, but honestly, this combo: c.mk xx lk spin kick, land, hp dp (2 hits) xx SA1 is an easier combo to pull off than a close s.mk into the super. I THINK, it’s because it’s a link, but I could be mistaken.
Now, to do this combo WITHOUT being 100% on the timing of it, you could do this to practice and learn it…
s.mk, pause, qcf, qcf +hp, release, mp, release, lp, release… Might seem like a lot of work, but you’re “piano’ing” the buttons. Since negative edge is in effect, you’ll get SIX opportunities to hit the button at the right time. Six because you get one on each press and one on each release. Now, this DOESN’T work if you release and hit at the same time. So if I release HP and hit MP at the same time, I lose a possible input.
Now, in SF3, there’s plenty of times that negative edge comes in hand. Activating Yun’s Genai Jin, hit confirming almost any super, doing walk up 720’s with hugo, cancelling hard-to-cancel moves into things, etc. etc.
Learning that, option selects, and basic footsies, and you’ll instantly become a better player in almost every fighter.
