DOSBox Staging

DOSBox Staging is a modern continuation of DOSBox with advanced features and current development practices.

It is a (mostly) drop-in replacement for older DOSBox versions—your existing configurations will continue to work, and you will have access to many advanced features.

For a detailed description of the project's scope please refer to the About page on our website.

Dynamically loaded dependencies

Slirp is built separately as a dynamic library (via vcpkg) and is loaded on-demand at runtime if available. Please refer to the dosbox-staging-ext project for further details. To check the version of this dependency included in our stable and dev build packages, check out the comments of the releases packages of the dosbox-staging-ext project.

For information on the optional Nuked SC-55 CLAP audio plugin, check out the plugin's GitHub repository (note Nuked SC-55 CLAP is not a DOSBox Staging project).
