Allow the game to use the in-engine graphical interface and the original save/load menu. Use it together with the "Ask for confirmation on exit" for a more complete experience.
Select music quality. The original determines the basic setup by hardware detection and speed tests, but also allows changes through the Game menu to some degree.
When playing the intro track, play from this point in it. Use this if the music gets cut off prematurely, or if you are unhappy with the way the music syncs up with the intro.
