Flycast can emulate the CPU (SH-4) and GPU (PowerVR2) perfectly, but it does not emulate the internal startup code. That code lives in the BIOS file. Without it, Flycast doesn't know how to "turn on" the virtual Naomi machine.
To get the most out of Flycast with the Naomi BIOS:
To run Naomi games on Flycast, you'll need a Naomi BIOS. The BIOS provides the necessary information for Flycast to emulate the Naomi hardware and load games. Without a Naomi BIOS, Flycast won't be able to run Naomi games.
If the game boots to a BIOS screen, it is often a sign of missing or incorrect BIOS files rather than a broken game ROM. Troubleshooting
