        "notes": "PokeMini is a Pokemon Mini handheld emulator ported to libretro.\n\nThe core has an embedded FreeBIOS (open-source replacement) compiled\ndirectly into the binary from freebios/freebios.c. This means the\nreal BIOS is never strictly required -- games will run with FreeBIOS\nalone, though compatibility may differ from the original firmware.\n\nBIOS loading sequence in the libretro port:\n\n1. PokeMini_Create() clears PM_BIOS (4096 bytes at $000000-$000FFF),\n   then loads FreeBIOS into it via memcpy (source/PokeMini.c:116).\n   PokeMini_FreeBIOS is set to 1.\n\n2. retro_load_game() calls PokeMini_Reset(0) after loading the ROM.\n\n3. PokeMini_Reset() checks forcefreebios (hardcoded to 0 in the\n   libretro port, libretro.c:499). Since FreeBIOS is currently loaded\n   and forcefreebios is 0, it enters the real-BIOS path\n   (source/PokeMini.c:503-508):\n     - Reloads FreeBIOS as a safety fallback\n     - Checks if CommandLine.bios_file exists on disk\n     - If found, overwrites PM_BIOS with the real BIOS via\n       PokeMini_LoadBIOSFile(), sets PokeMini_FreeBIOS to 0\n\n4. If bios.min is missing, FreeBIOS stays loaded and emulation\n   proceeds normally.\n\nFile path construction (libretro.c:565):\n  sprintf(CommandLine.bios_file, \"%s%cbios.min\", g_system_dir, slash)\nThe core looks for bios.min directly in the system directory root,\nno subdirectory.\n\nThere is no core option to toggle FreeBIOS in the libretro port.\nThe standalone PokeMini has a forcefreebios setting, but the libretro\nwrapper hardcodes it to 0 (always prefer real BIOS when available).\n\nFreeBIOS (freebios/freebios.min) is 4096 bytes, a clean-room\nreimplementation. It is NOT the official Nintendo Pokemon Mini BIOS.\n",
