Hrmmmm, small prob.... the music in Road Avenger isnt CDA, its all encoded right into the video files. There are three tracks on the CD of music, 2 10 second clips that sound like they would be loops and a 1 and a half minute clip that i have no clue where in the game it is, i think its the music at the score board at the end of your game. But i really dont know where in the game these are used exactly... havent played this game since i beat it back it 8 years ago.
SO, unless you know what files are the video, and then how to extract the music files from it, i aint getting the music off.
