The Polymega console supports side-loading official BIOS files by placing them in a “bios” folder on an SD card or USB drive. If the system detects mpr-17933.bin there, it will use that file instead of its own pre-installed BIOS.
Because the Sega Saturn utilized a notoriously complex architecture—featuring two Hitachi SH-2 RISC processors and two distinct graphics chips (VDP1 and VDP2)—accurate emulators rely on this raw binary code to sync the hardware components just as an original console would.
