        "notes": "Frozen snapshot of VBA-M circa 2011, optimized for libretro by Squarepusher.\n\nBuilt-in HLE BIOS (myROM array, src/gba.c:8930) handles all standard SWI\ncalls. No external BIOS file needed for most games.\n\nBIOS loading gated by HAVE_HLE_BIOS (build/Makefile.common:3) and core option\nvbanext_bios (default: enabled). When enabled, retro_init resolves gba_bios.bin\nin system_dir (libretro/libretro.c:213-218). CPUInit loads via utilLoad(),\nvalidates size == 0x4000, sets useBios = true (src/gba.c:12943-12950). On\nfailure, myROM is memcpy'd as HLE fallback (src/gba.c:12954-12956).\n\nWith real BIOS, execution starts at 0x00000000 (BIOS entry point). Without,\njumps to 0x08000000 (ROM entry), skipping boot animation\n(src/gba.c:13134-13151).\n\nUpstream VBA-M CPUInit (src/core/gba/gba.cpp:5152-5180) is functionally\nidentical. No divergences in BIOS handling.\n",
