Supports\n.dsk, .sna, and .kcr file formats.\n\nAll system ROMs are compiled directly into the core binary as C byte\narrays. No external BIOS files are required.\n\nEmbedded ROMs (crocods-core/):\n  - cpc6128.bin.c: cpc6128_bin[32768] - CPC 6128 OS (16KB) + BASIC 1.1 (16KB)\n  - romdisc.bin.c: romdisc_bin[16384] - AMSDOS disk controller ROM (16KB)\n\nROM initialization in InitMemCPC() (crocods-core/vga.c:185-200):\n  - ROMINF (lower ROM, 16KB): first half of cpc6128_bin (OS)\n  - ROMEXT[0] (upper ROM slot 0, 16KB): second half of cpc6128_bin (BASIC)\n  - ROMEXT[7] (upper ROM slot 7, 16KB): romdisc_bin (AMSDOS)\n\nCalled from HardResetCPC() (crocods-core/platform.c:1024-1035) using\nthe extern byte arrays directly. No filesystem ROM loading exists in\nthe libretro path.\n\nA Multiface ROM loader exists (crocods-core/multiface.c:53-64) that\nreads LocRomMulti via fopen(), but InitMultiface() is never called\nfrom the libretro build or platform.c. Dead code in libretro context.\n\nThe core does not request retro_system_directory or declare any\nfirmware entries in the .info file. need_fullpath is false.\n\nOnly the CPC 6128 model is emulated (no CPC 464/664 selection).\n",
