The BIOS path is the general.bios_path\nkey of that file, default \"bios.bin\", overridden by --bios on the command line.\nref: src/platform/sdl/main.cpp:288-293, src/platform/core/src/config.cpp:36,\n     src/platform/core/include/platform/config.hpp:17, src/platform/sdl/main.cpp:98-102\n\nThe BIOS is required. BIOSLoader refuses a missing path, a directory, and any\nsize other than 16 KB, and the frontend prints the reason and exits. There is no\nbuilt-in replacement. bios_skip only jumps past the boot screen after the BIOS\nis loaded.\nref: src/platform/core/src/loader/bios.cpp:17-48, src/platform/sdl/main.cpp:177-192,\n     src/nba/src/core.cpp:42-44\n\nROCKNIX patches config.toml and keymap.toml to /storage/.config/nanoboyadvance/\nand its config.toml sets bios_path = /storage/roms/bios/gba_bios.bin.\n",
