About
Spacebase DF-9 is a space-station simulation game developed by Double Fine Productions, officially released in 2014 for Windows, OS X, and Linux; after Double Fine ended official support in 2015, the community continued development from an open-source fork until that fork was itself abandoned in 2023. This is a community-maintained fork of Double Fine's Spacebase DF-9, open-sourced in May 2015 under the CPAL-1.0 license and written largely in Lua using the MOAI SDK. It installs by copying modified files over an existing Steam installation of the original game (on Linux via an install script, or on Windows via a separate installer), and its final unofficial patch, v1.09, shipped in January 2023.
How it differs from the original
As a patch-style fork rather than a full rewrite, it overwrites the original game's files directly and still requires an existing Steam installation of Spacebase DF-9; save files aren't necessarily backwards-compatible after installing it.
Getting started
On Linux, an install script copies the modified files over an existing Steam installation of Spacebase DF-9, with a backup and a restore option; on Windows, a separate installer is available from the project's website. The maintainers note they are no longer accepting bug submissions.
History
Double Fine released the game's Lua source code in October 2014, and after the studio wound down official support the community kept releasing unofficial patches from 2015 through a final v1.09 release in January 2023, after which no further patches were planned.
Known limitations
- compatibility: Save files may not be backwards compatible with original game.
