editing game

Hello, I created this topic because I have not found one that solved my doubts ... I have a room of saint seiya chapturer sanctuary for ps2, I opened it with afs explorer and changed some sounds, took some original speech in Japanese and put the lines in English, was very nice but could only do this in a few lines, I wanted change as well the voices of struggle, that is, those cries of agony attack what they do during the game when it is fighting, "it's BATTLE_VOICES" but they are packaged in a "bin" and can not do anything with these files the goal is to extract the original voices and put my in the right format that is within these files bin ... if someone can help me or already made something pareciso with football games or who knows anything about that thanks!
