Astral Chain (captainj-sparrow)

captainj-sparrow/astral-chain-pc-recomp

A static recompilation of Astral Chain, the 2019 Switch game, into a native Windows x86-64 application with a Vulkan renderer, built on the pipeline of TotK Recomp, Valiantsin Dzerakh’s Tears of the Kingdom recompilation, which is also in the catalog. Its installer extracts the game’s data, merges the 1.0.1 update, lifts the code to C, and builds astralchain.exe on your PC, so the result contains the game and is for your own use only; it ships no game data and no code derived from it. The README says it is playable through the story, with its audio and save data, and that outside testing (Reddit, YouTube) has taken it from the intro to the credits with no known visual issues. It runs at 60 fps by default (with a 30 fps option and a cutscene speed fix), with custom resolutions, FSR 1 upscaling up to 4K, anisotropic filtering up to 16x, an in-game settings menu (F1), keyboard, mouse, and gamepad with remapping, rumble, and gyro, and mods and cheats in the emulator formats. Shaders are built during play; preparing shaders at install and a Linux release remain planned. It published seven releases between November 3 and 4; the latest, 0.3.0, adds 60 fps and the 1.0.1 update. There is another Astral Chain recompilation in the catalog.

You needYour own copy of Astral Chain for Switch, dumped from your console: the base game (version 1.0.0, XCI or NSP) and the 1.0.1 update (NSP), and your keys (prod.keys). 64-bit Windows 10 or 11 (x86-64 with at least SSE4.2), a Vulkan 1.3 graphics card, about 14 GB for the installed folder, and about 11 GB of temporary space while the update is merged.

Astral Chain (swaymun)

swaymun/AC-Recomp

An experimental static recompilation of Astral Chain for macOS, with Linux and Windows ports in progress. The game’s Arm code is compiled ahead of time to C++ and built as a native program; the system services and the NVN graphics API are reimplemented on the host (NVN on Vulkan, with the shaders translated offline to SPIR-V), with no emulator or JIT. On macOS (Apple silicon, Vulkan on Metal through MoltenVK) it boots, gets through the opening sequence, character creation and the File 01 motorcycle chase at a stable 30 fps, with audio; on Linux and Windows it reaches that same chase. The README itself says the game can’t be played from start to finish and that saving and reloading are untested. It has a macOS launcher, FSR 1 upscaling, and experimental options for internal resolution and a 60 fps mode. v0.1.0 (macOS), from October 19, is the only release. It states that most of the code was written by Claude through Claude Code; 1 of its 2 commits lists it as a co-author.

You needYour own copy of Astral Chain 1.0.0 (base game, no update) as an NSP, with the keys from your own console; other versions are refused. On macOS, a Mac with Apple silicon, macOS 13 or newer, the Xcode Command Line Tools, Homebrew and about 25 GB free; the first build takes 30 to 90 minutes. The system fonts from your firmware are optional.
