Emulators for simpler consoles (e.g., Genesis, SNES) are often high-level emulations (HLE) . They re-implement the BIOS functions from scratch in software. The Saturn, however, is so complex that reverse-engineering its boot process is incredibly difficult. Therefore, most Saturn emulators use low-level emulation (LLE) , which actually executes the original BIOS code. Without the real BIOS file, RetroArch’s Saturn cores cannot boot games. sega saturn bios retroarch
You might wonder: "Will Saturn emulation ever become BIOS-free like PS1?" The PlayStation 1 core (DuckStation/SwanStation) can emulate the BIOS via HLE, though accuracy suffers. For Saturn, the situation is more dire because of the CD block’s security ring check. Without the original BIOS, you cannot correctly emulate how the Saturn’s SH-2 CPUs interact with the CD controller. A fork of UYBA focused on performance and upscaling
