The first target is a faithful boot to the Locomotive BASIC prompt, followed by keyboard input, timing accuracy, audio, and disk support.\n\n## Current Status\n\nCurrent development focus:\n\n- Go module and package layout.\n- ROM loading and size validation.\n- CLI flags for ROM, AMSDOS, disk image, model, and scale.\n- Z80 adapter using `github.com/user-none/go-chip-z80`.\n- CPC6128 memory/ROM bus foundation.\n- Initial Gate Array, CRTC, and PPI I/O skeleton.\n- CPC keyboard matrix path through PSG/PPI, with live Ebiten host-key mapping.\n- Live Ebiten display with CPC palette conversion, border fill, and line-doubled aspect.\n- Project specs in `spec.md` and staged plan in `plan.md`.\n\n## ROMs\n\nROM files are local runtime inputs and should not be committed.\n\nExpected files while developing:\n\n- `cpc6128.rom`: 32K OS+BASIC image.\n- `amsdos.rom`: optional 16K AMSDOS image for later disk support.\n\n## Run\n\n```sh\ngo run ./cmd/cpcgo --rom cpc6128.rom --amsdos amsdos.rom\n```\n\nAt this stage the command validates inputs, runs the emulated machine headlessly, and can dump a crude framebuffer that reaches the BASIC prompt.\n\nHeadless boot probe:\n\n```sh\ngo run ./cmd/cpcgo --rom cpc6128.rom --amsdos amsdos.rom --probe-instructions 1000000\n```\n\nCrude framebuffer dump:\n\n```sh\ngo run ./cmd/cpcgo --rom cpc6128.rom --amsdos amsdos.rom --frame-instructions 1000000 --dump-frame /tmp/cpcgo-frame.png\n```\n\nLive Ebiten UI:\n\n```sh\ngo run -tags liveui ./cmd/cpcgo-ui --rom cpc6128.rom --amsdos amsdos.rom\n```\n\nTo capture the aspect-correct live view, add `--screenshot /tmp/cpcgo-live.png` and press `F12`.\n\n## Test\n\n```sh\n./test.sh\n```\n\n## License\n\nAGPL-3.0-or-later.
