You downloaded a "Lite" or "RIp" version, not the "Full" CDI. Fix: The full version should be between 780MB and 800MB. If it is 650MB, it is missing audio tracks.

The Sega Dreamcast was the first in a new generation of gaming consoles, preceding the PlayStation 2, Xbox, and Nintendo GameCube. It was designed to be a more powerful and flexible console than its predecessors, with a built-in modem for online play and a 128-bit SH-4 processor. The Dreamcast was an instant hit, with its sleek design and impressive game library.
