Technical notes

Emulates Enterprise 64/128, Videoton TVC, Amstrad CPC 464/664/6128, and ZX Spectrum 16/48/128. All ROMs are embedded in the binary since v1.1.0; external files override built-in data. Content type is auto-detected and determines machine configuration and ROM selection. Custom ROM mappings are possible via .ep128cfg config files placed in ep128emu/config/ or next to content. The .info declares epd19hft.rom and zt19hfnt.rom which are phantom entries never referenced in code. The .info omits epdos16f.rom and exdos14isdos10uk.rom which are used by the code. SDEXT, ReSID, and MIDI port features are compile-disabled in the libretro build.
