On the main menu, before pressing Space to start the VS mode, move the cursor over the spinning Polygon logo in the bottom right corner. Now press space, and if you have done it right, you will get a much cooler VS Select. VS Secret #1 is Stan's Secret.

Remix the Normal VS Select music - on the normal VS Screen, press 'B' to remix the music to that of Tekken 2. VS Secret #2 is Stan's Secret.
