The arcade system, built on Dreamcast hardware, requires specific firmware known as Naomi BIOS files to initialize its hardware and load games. Without these files, emulators like Flycast or RetroArch cannot simulate the arcade board's environment, preventing games from booting. Why BIOS Files Are Essential

Because the architecture was so similar to the Dreamcast, the Naomi system became one of the most heavily emulated arcade platforms. It allowed arcade-perfect ports to the Dreamcast and, later, near-flawless emulation on modern PCs. However, unlike home consoles which have standardized software across regions (mostly), arcade hardware operates differently, making the BIOS the unsung hero of the operation.
