        "notes": "Libretro port of Mednafen's PCE module (libretro.cpp:30), with SuperGrafx and CD support. The BIOS is loaded from the system directory at CD-ROM load time via PCE_LoadCD() in mednafen/pce/pce.cpp:441-460, so HuCard content runs without it. Core option \"pce_cdbios\" selects which card image to use (default: System Card 3). DetectGECD() auto-detects Games Express discs and switches to the pce.gecdbios setting, fixed to gexpress.pce. Arcade Card mode (pce_arcadecard option, enabled by default) extends System Card 3 with extra RAM mapping via the SYSCARD_ARCADE enum. No hash or size validation on BIOS load: file_open() then HuC_Load() reads the data directly. DetectSGXCD() reads sector data to decide SGX mode but uses the same BIOS files.\n",
