BIOS stands for Basic Input/Output System. In original hardware (like a Sony PlayStation or a Sega CD), the BIOS is a small chip on the console’s motherboard that contains the low-level instructions required to boot the system, initialize the hardware, and run games.
In emulation, the BIOS file acts as a translator. Without it, many emulators (or RetroArch cores) simply do not know how to behave like the real hardware.
If you cannot find a legitimate RetroArch BIOS pack archive or you want to avoid legal headaches, some cores offer limited BIOS emulation.
The bottom line is: for accuracy, you need the real BIOS.
