[quote name='anathema728']whaat since when was option's main dhalsim? tell me how to play the cammy vega akuma matchups[/QUOTE]
Now those are matchups that trouble me as sim. For Cammy, sim's b.rh still beats Cammy's j.rh. Vega, I have no idea. I suppose short slide, when timed right beats wall dive and st. far lk beats slide. Teleport doesn't really work for some reason. Akuma, make sure he doesn't start mixing you up with demon flips, jump ins and air fbs. B.rh beats the demon flips and short slide beats jump in fireballs.
Try to mix up the back teleports and fireball, and never empty teleport. At least do it on knockdown or after you ave a fireball. And don't fb at a certain distance taking into account sim's horrible fb recovery.
Sorry, that's all I can really recall, I still have trouble with wall diving Vega and rushdown Akuma.
Also, pokes are a saving grace. It changes up the timing of the other person but if you miss a heavier poke, it's a free jump in. Play around with his normals and know exactly when to throw out which poke. i.e. set cpu to jump in training mode and see which pokes keep them down, knock them out of the air, or those that just totally whiff.
Also, if someone is just plain FADCing your limbs, throw out a fb or stick with the fast limbs, i.e. st.lk to b.st.lk.
