Street Fighter IV PC mod question: BSR


Newbie here

Im new to modding, but Ive learned that files that end with .emz work successfuly on my PC. However I got some mods that have files that end with .bsr, .csb, .emb, .emo, and I have no idea what to do with them. I have no idea where I should put them in my files so that they can work. Can someone help me?
