So I really like some of the background music in the POL viewer and wanted to be able to listen to it outside of the game. I found this site, which is a complete FFXI music hacking guide. It mostly covers converting your own .wav files to .bgw files so that you can have your own songs play in the game. And also points out a program you can use to properly convert a wave file so that it will also repeat in game like the normal game music. Cool thing is, the converter program will also convert .bgw files to .wav files! So I used it to convert my favorite songs to .wav files then used the Plus! Digital Media Edition Audio Converter to convert it to a .wma file. Weeeeee!
