MartyPC – A Cycle-Accurate IBM PC/XT Emulator

MartyPC is a cycle-accurate emulator of early IBM PCs and compatibles, developed in Rust and available across Windows, Linux, and macOS platforms. Designed primarily as a development tool for retro PC programmers, it features extensive debugging capabilities and cycle-by-cycle CPU execution measurement, with accuracy validated against real 8088 hardware using an Arduino microcontroller. The project, which began in April 2022, is currently at version 0.5.0 in development and available through both periodic releases and automatic builds on GitHub.
