NOTE: Using SIDPLAY with a Gravis Ultrasound (GUS) or compatible Although the GUS support is based on a library from the official GUS SDK, there are some problems on various machines with different configurations. You are advised to use a new version of the MegaEm or SBOS and run this application in Sound Blaster mode. The GUS support doesn't make use of the GUS's special hardware capabilities, anyway.
