The GDI format is the closest thing you can get to the authentic Dreamcast experience in the digital realm, preserving every single byte of data exactly as it existed on the original GD-ROM.

In the early 2000s, ripping groups created .CDI (DiscJuggler) files to shrink GD-ROM games down to fit onto standard 700MB CD-Rs for burning. To achieve this, hackers downsampled audio, compressed video textures, or removed content entirely.
