Sound Test

After booting up the game, wait until the prompt tells you to insert the User Disk into Drive 1. Insert Disk C four separate times (in and out) into Drive 0, then re-insert the System disk. If done properly, the Sound Test will appear.

The Sound Test gives you access to all the music (including unused tracks) and sound effects. While you play a music track, the mascots will dance on the screen.
