openMSX

openMSX is an emulator that reproduces the hardware and software environment of the MSX home‑computer series. It runs MSX programs, games and peripherals on modern operating systems, providing support for a range of configurations such as different MSX models, external disk drives, joysticks, data recorders and printers. The emulator includes a graphical user interface that replaces earlier on‑screen menus, and it offers an integrated debugger for inspecting and controlling execution.

The software is aimed at enthusiasts, developers and researchers who need to run legacy MSX software or develop new applications for the platform. Its “setups” feature lets users define and automatically load complex hardware arrangements, while recent updates have improved flash‑chip emulation accuracy. The project supplies pre‑built binaries for macOS, Windows and Linux, as well as source code for custom builds.

openMSX is maintained as a stable, actively developed project with regular releases that add interface enhancements, bug fixes and support for newer graphics APIs. It is distributed under an open‑source license and can be obtained from its website or repository.
