Nightly 2026-11-05 (9441f8c2)

Automated nightly from 9441f8c2a1d0337abf1b32f67a8adddd135ee02e, built 2026-11-05. This is a development build.

Includes Windows x64 and arm64 (standard and portable), Linux x64 and arm64, and universal macOS packages, and the source of the LGPL FluidSynth library that they include. Your own SimCity 2000 Special Edition for Windows 95 (1996) files are required.

CI passed the generated-data suite, editor parsing, and startup checks with Dummy audio. The full local release suite and cross-platform gameplay checks are not run here.

Windows packages are unsigned. The macOS app is ad-hoc signed and is not notarized. Linux x64 needs GTK 3 and WebKitGTK 4.1. The arm64 packages cannot show the newspaper.

OpenSC2K 0.2.0

OpenSC2K 0.2.0

Includes Windows x64 and arm64 (standard and portable), Linux x64 and arm64, and universal macOS packages, with SHA-256 checksums.

Your own SimCity 2000 Special Edition for Windows 95 (1996) files are required. Original game assets are not included.

Installation instructions

CI passed the generated-data suite, editor parsing, and startup checks with Dummy audio. The full local release suite and cross-platform gameplay checks are not run by this workflow.

Windows packages are unsigned. The macOS app is ad-hoc signed and is not notarized. Linux x64 requires GTK 3 and WebKitGTK 4.1. The arm64 packages cannot show the newspaper.

Change Highlights:

• Faster game engine. The simulation, file formats and rendering now run in a native Rust library, so the game is much faster, especially on large maps.
• Maps can now be up to 4096×4096. Maps larger than 128x128 use the new SC2X save format.
• More game versions can be imported. You can now import from the DOS, Macintosh, Windows 3.x and demo versions, and from mounted CD-ROMs.
• New music playback. MIDI music now plays through FluidSynth, using your system's General MIDI sound set or a SoundFont you choose.
• ARM64 builds. There are now Windows and Linux arm64 packages.
• Rebindable controls. You can rebind keyboard and mouse controls in a new Controls tab.
• Tool improvements. Tool groups remember your last subtool. Holding the mouse button repeats single-click placement.
• Interface additions. Option to rename your city, Tunnels and Subways views, fixed the Zones data view, fixed neighbor connection signs.
• The newspaper now works in every package.
• SCURK. New graphical tile browser and better artwork copying.
• New Debug menu, debug layers and Tile Inspector.
