stands for Gigabyte Disc Image . It is the most accurate, raw, and complete copy of an original Sega Dreamcast GD-ROM (Gigabyte Disc Read-Only Memory) . : High-density GD-ROMs typically contain three or more
This multi-file structure is intentional. Because Dreamcast held roughly 1.2 GB of data—nearly double a standard CD-ROM—the GDI format is required to preserve that high-density data without modification. GDI vs. CDI: Which is Better? CDI : To run these high-fidelity images smoothly
Unlike a standard CD-ROM which holds roughly 700 MB, a Dreamcast GD-ROM can hold up to of data. Because standard CD burning software and ISO formats could not easily handle the high density or the specific layout of these discs, the GDI format was developed by the emulation community to create a 1:1 (perfect) digital copy of the original game.
