simply extract files to somewhere handy like the desktop.

Start game in OOTP5....reduce screen (click "-" symbol in upper-righthand corner of screen)
and then click on approprite file to play.  Click on game in bar at bottom of the screen
and enjoy listening to national anthem in game!

I have included "Take me out to the Ballgame" for all you freaks (like myself)
who just have to listen to that 7th inning stretch classic for any game to really
be complete.  Enjoy.
