Hi Everybody, I'm new here.
I just managed to get this very tricky achievement. I try to explain how i did it:
First of all, set your stars to 0 and keep your timer on. This can be very useful in tricky situations. I chose Ryu to play with and the best way you achieve this is having your first match against Ryu.
For the most opponents it goes like BugaJ75 Returns explained above, but i try to add something on special charakters:
Zangief: Just go into your corner and use your high kick while youre jumping all the time. With this method you beat him in seconds.
Chun-Li. Take advantage of her wall jump! If she's doing it, dragon punch her out of it. Repeat this mixed with fire balls and the win is yours!.
Balrog: One of the easiest opponents in my opinion. Just spam fire balls and if he's close to you, block while you crouch and then sweep him. Repeat it several times.
Vega: There are 2 methods you should learn to implement: If he does the wall jump, dragon punch him (s.o Chun-Li). The second attack of him is the wall climbing. Wait until he jumps off and get him with the dragon punch there. Works every time!. If he's on the ground, do your fire balls but keep distance to him!
Sagat: Like explained he tries to get you in a corner. Just jump and kick him after the "fight" slogan disappeared. Then keep distance and wait until he's doing his fireballs. This is your chance. Jump over them and press High kick. Then immediately jump backwards and wait for him to start over again. Repeat this several times and he's gone (Try to practice it in the Training mode first)
Bison: This one is really though. i haven't got a turbo controller so i tried the conventional way: Mix your fire balls and low(!) dragon punch to get rid of him. Timing here is the key to success. If he's jumping or trying his headstomp, keep distance and kick him with a high kick (be on the ground here!). Block his Psychocrusher and dont' get nervous if he pushes you in a corner. Just wait and try to sweet him. The fire ball here can be your best friend too. Practise this in Training mode first too to get used to his fighting style.
Be patient and don't lose your cool while you're playing.
BTW: sry for my bad englisch, I'm from Germany.
