About openMSX
openMSX emulates MSX home computers with a strong focus on accuracy. Version 20.0 introduced a new graphical interface, and version 21.0 improved it further, especially the debugger, and added setups: saved MSX configurations such as a specific machine with a disk drive, joystick and printer that can be loaded and started automatically.
Builds are available for Windows, macOS on Intel and Apple silicon, and Linux, with older Android and OpenDingux builds and nightly development builds.
