GoKawiilMartyPC brings cycle-accurate 8088 emulation to IBM PC/XT retro development
MartyPC is an open-source emulator for early IBM PC and compatible machines, running on Windows, Linux and macOS. Built from scratch by a hobbyist learning Rust, it now offers cycle-by-cycle accurate emulation of the Intel 8088 CPU, validated against a real 8088 chip wired to an Arduino MEGA.
GoKawiil's interpretation of the reporting above, not reported fact.
Most PC emulators prioritize speed or compatibility over precision, but MartyPC targets retro developers who need to see exactly how their code behaves at the hardware level, including timing quirks like the prefetch queue. This level of fidelity, verified against real silicon, makes it a serious tool for debugging and studying vintage 8088 software rather than just playing old games.
- MartyPC emulates early IBM PC/XT systems with cycle-accurate 8088 CPU behavior.
- Its accuracy was validated by comparing execution against a real 8088 chip via an Arduino MEGA setup.
- The project targets retro PC developers with debugging and logging tools rather than casual users.
