bnk files are encrypted protected files from my research to see if they were easily extract the soundtrack and put on my mp3 player.
What I ended up doing was get an mp3 recorder and recorded the music. Hit the ESC key and waited for the music to loop again. Then edit it into a single track file.
I have 9 soundtracks that I listen to. About 20 are probably left in the game.
Found a program called mp3 direct cut that was free and works nice. Need to hit rec and then play to actually start recording music.
