Supports CPC 464,\nCPC 464 with DDI-1 disc interface, CPC 664, CPC 6128, and CPC+ (Plus) models.\n\nAll system ROMs are compiled directly into the core binary as C header\narrays in cap32/rom/*.h. No external BIOS files are required.\n\nEmbedded ROMs (cap32/cap32.c:345-349, cap32/slots.c:33):\n  - cap32/rom/464.h:    OS464_BASIC10[32768]  - CPC 464 OS + BASIC 1.0\n  - cap32/rom/664.h:    OS664_BASIC664[32768] - CPC 664 OS + BASIC 1.1\n  - cap32/rom/6128.h:   OS_BASIC11[32768]     - CPC 6128 OS + BASIC 1.1\n  - cap32/rom/amsdos.h: AMSDOS[16384]         - AMSDOS disc ROM\n  - cap32/rom/6128p.h:  OS_6128P[65580]       - CPC+ system cartridge\n  - cap32/rom/cpm.h:    CPM, CPM_SYS          - CP/M boot memory dumps\n\nROM selection in emulator_select_ROM() (cap32/cap32.c:1081-1111):\n  - CPC 464:     OS464_BASIC10, AMSDOS in slot 7 when the content is a disc\n  - CPC 664:     OS664_BASIC664 + AMSDOS in slot 7\n  - CPC 6128:    OS_BASIC11 + AMSDOS in slot 7\n  - CPC+:        OS_6128P loaded as system cartridge via cpr_load()\n\nCore option \"cap32_model\" lists \"464DDI\" (libretro/libretro-core.c:501),\nbut update_variables() matches only 464, 664, 6128 and 6128+ and leaves any\nother value on the 6128 default (libretro/libretro-core.c:1035-1039).
