These are SameBoy-authored\nreplacements, not Nintendo originals.\n\nThe libretro port (boot_rom_load, libretro/libretro.c:513-589) tries to load\nan external boot ROM from the system directory first. Filename is\nconstructed as \"{model}_boot.bin\". If missing, the embedded boot ROM\nis used as fallback.\n\nBoot ROM selection depends on the sameboy_model core option\n(request_boot_rom in Core/gb.c:1587-1625):\n DMG_B -> GB_BOOT_ROM_DMG -> dmg_boot.bin\n SGB_NTSC/PAL -> GB_BOOT_ROM_SGB -> sgb_boot.bin\n SGB2 -> GB_BOOT_ROM_SGB2 -> sgb2_boot.bin\n CGB_A..E -> GB_BOOT_ROM_CGB -> cgb_boot.bin\n AGB_A/GBP_A -> GB_BOOT_ROM_AGB -> agb_boot.bin\n\n.info declares firmware_count=2 (dmg, cgb only).
