This paper examines the Sega Dreamcast BIOS files commonly distributed as dc_boot.bin (often called dcboot.bin) and dc_flash.bin. It summarizes their roles in Dreamcast hardware and emulation, legal and preservation issues, technical structure at a high level, and best practices for researchers handling these files. The goal is an accessible, concise reference for archivists, emulator developers, and retrocomputing researchers.
