The Astral Chain on PC received an update for its unofficial recompilation for Windows on November 4, 2026. The independent project by captainj-sparrow converts the Nintendo Switch game's code into a native executable for computers, with graphics processed by Vulkan. This is not an official release by Nintendo or PlatinumGames.
What changed in Astral Chain on PC?
Version 1.0.0 introduced pre-compilation of shaders during installation. According to the developer, this step aims to avoid minor stutters while the game prepares graphic effects during the first playthrough. However, the actual gain depends on the computer, and Allves Games has not yet performed independent measurements.
On November 5, update 1.0.1 fixed action response times and camera smoothing in 60 FPS mode. Also on the same day, the author released version 1.0.2 to fix missing or flickering shadows under specific conditions, especially at the police headquarters. Therefore, version 1.0.0 is no longer the most recent update.
Astral Chain on PC: resolution and controls
In addition, the project offers adjustable resolution, keyboard, mouse or gamepad controls, modification support and image scaling options. The developer states that the story can be played from beginning to end, but this is a statement from the project, not an independent test by Allves Games.
In turn, the 60 FPS mode caters to gameplay, but some cinematic scenes may remain limited to 30 FPS. Furthermore, the developer reports the following requirements: 64-bit Windows 10 or 11, a processor with SSE4.2, a graphics card compatible with Vulkan 1.3, and disk space to generate the installation. Finally, this project for Windows is not the same experimental re-compilation initiative for macOS.
How to install Astral Chain on PC?
The project's official installer does not include the game. Therefore, you need to own a proper and legitimate copy of Astral Chain and provide the files required by the program, respecting the versions indicated in the release notes. According to the author, to apply update 1.0.2, simply point the installer to the existing folder again; the procedure preserves saved data.
Now, to install the port, follow the procedure documented by the developer:
- Download the Windows installer for the latest version from the releases page and extract the ZIP.
- Run Astral Chain-Setup.exe and select the files from your own legitimate copy of the base version 1.0.0, in addition to the legally obtained keys file from your own console.
- Choose the language and installation folder and wait for the file preparation and compilation.
- Run astralchain.exe in the chosen folder. To update an existing installation, select the same folder in the installer, according to version 1.0.2 release notes.
The developer reports that the original game's update 1.0.1 is not compatible. Check the requirements in the official releases repository. Allves Games did not perform an independent installation test. Do not download ROMs, third-party keys, or packages claiming to include the full game.
Where to follow upcoming fixes?
Finally, the release notes for versions 1.0.0, 1.0.1, and 1.0.2 are on the project's official page. As this is a community recompilation, features, compatibility, and eventual bugs may change quickly. Linux support was mentioned as a plan, not a confirmed available release.
