For technical specifications, the dreamcast.wiki pages on GDI format and GD-ROM look promising. For emulators, the batocera wiki pages on Redream and Flycast are relevant. For ROM sources, the Internet Archive has several collections. For format comparison, a retropie forum post explains the difference between GDI and CDI. For legal information, the dcemulation.org and emulation.gametechwiki.com pages are useful. I will open these promising links to gather more detailed information. opened pages provide detailed information. The GDI format page explains the structure.
