The Dreamcast BIOS was designed to be a digital moat around Sega’s kingdom. Following the catastrophic losses caused by easy piracy on the PlayStation and the Saturn’s complex but ultimately cracked architecture, Sega sought a multi-layered defense. The BIOS’s authentication system, combined with the proprietary GD-ROM format (which held 1 GB instead of a CD’s 700 MB), was meant to keep pirates at bay.
The Dreamcast BIOS, also known as the "GD-ROM BIOS," was developed by Sega in collaboration with Hitachi, who manufactured the GD-ROM (Gigabyte Disc Read-Only Memory) drives used in the console. The BIOS is stored on a dedicated chip on the motherboard and is executed when the console is powered on.

To run Dreamcast games on emulators like , Reicast , or RetroArch , you typically need two specific files extracted from an original console:
