Street Fighter IV on PS3......HELP!

I unlocked all the characters except for Seth, and the other two guys.

To unlock the first two you have to complete Arcade and have at least 2 Perfects and 2 Ultra Finishing Moves.

I did it on Easiest (to save time) and then I did it on (Medium).

STILL NO UNLOCKABLE CHARACTERS! WTF!!!!!!!!!!!!!!!!!!!!!!!!!

I did 3 on EASIEST and 2 on MEDIUM. Still..no characters. And of course I had to use continues!asherlin77

Well, there's your problem. I'm pretty sure you can't use continues at all if you want to unlock them.

Maybe this site will help, I don't know though.
