Yes. I have been playing Street Fighter IV lately. However, I failed to unlock Gouken and Akuma. I have no problem to unlock Sakura, Dan, Cammy, Fei Long, Gen and Rose though. I searched lot of places. Some websites give me the wrong information and some did a great job. Yes… I unlocked Gouken and Akuma already. Looking forward to unlock the last one ~ Seth.
To make the unlock faster and easier. Set the game setting to easiest and 1 round match. And don’t lose in any match and don’t continue. Akuma or Gouken will show up after you beat Seth.
