I've been playing Street Fighter since SF2 but I was used to only mashing buttons randomly and trying to finish the playthrough and see the ending thanks to limitless continues or easy modes. Recently I've decided to play like a real man. I've started SSFIV AE from the easiest difficulty and whenever I finish the playthrough without continues, I've increased the difficulty (I don't know is it the right way to improve myself but seems working for now). Lastly, I've finished very hard difficulty and now I'm trying to finish the hardest.
My problem is, whenever I start a combo and try to finish it with a super/ultra combo, I end up with a Shoryuken and lose all my momentum, even getting easily punished(I've lost lots of matches just because of this). Whatever I do, I can't get over with this problem. I'm playing with a regular Xbox controller-like gamepad and my character is Ryu.
Is there anyone that could help me out?
