Smash Ultimate PC program downloads
Updated · Covers WindowSmash v0.2.0-alpha.1 and OpenSmash runtime-c2ca705
Download the source ZIP for your project and platform, unpack it, then open its installer. Both projects are prereleases; OpenSmash’s small runtime ZIP supplies part of the build, so start with the source ZIP.

These are repository source archives, with no game included. Unpack the ZIP before opening the named file. The archive folder name ends in its commit; its install script is what identifies the platform path. An installer that updates its source can move to a newer version during setup.
Use the version table below to identify the source ZIP and prerelease. If the installer updates itself, follow the setup instructions for that newer version.
Source archives and runtime dependencies
WindowSmash’s latest alpha release is source-only: it has no attached executable or runtime asset. For the current installation path, use the source ZIP above; the older Windows runtime belongs to the older game-version path.
For OpenSmash, choose Code → Download ZIP in the repository. The installer obtains its own runtime package and checks its hash. Manually combining the newest source with an older runtime can make it reject the package or require a different build path.
Before opening an installer
- Open the project’s repository linked above.
- Check the project name and maintainer.
- Read the alpha or prerelease label.
- Choose the source installer for your operating system.
Keep the source version and its matching runtime together. Use the installer’s selection if an older article names a different package.
Choose your OS guide
Continue with Windows, Linux and Steam Deck or WindowSmash on Mac. Each platform page takes you from the files you need through installation and first launch. Use game-file layouts if you need help identifying a folder.
