just bought street fighter alpha the warrior's dream on the psn, but not sure how 2 unlock the hidden characters, could u tell me how 2 unlock them, which characters and how many hidden characters there are, i would really appreciate the help, thanx.

thanx 4 the info, really appreciate it, but if u don't mind i have a few more questions, which characters have Bison as their final boss, thought that Ryu was one of them but occasionally i get Sagat as the final boss, so would like 2 know which characters have bison or akuma as final boss, also what bonus game modes are there i've unlocked Team Mode but got the feeling there's another mode, appreciate the help.
