BIOS validity check: byte pattern at offset 1 (\\x00\\x08\\x3c\\x3f) or string \"PS compatible\" at 0x12c (frontend/libretro.c:3632, 3646-3651): a file failing it is skipped, hence validation [size, signature]. Files named \"unirom\" (case-insensitive) are explicitly skipped. Region fallback: if the matching-region BIOS is missing, any available region BIOS is used over HLE. Three region slots: US (index 0), JP (index 1), EU (index 2) stored in Config.Bios[].\n",
