Chrono Trigger (Nintendo DS): Egg of Time: Native PC Port of Chrono Trigger DS

A project called Egg of Time has produced a native PC port of the Nintendo DS version of Chrono Trigger by statically recompiling the game's ARM9 code into C11, with development assisted by Anthropic's Claude via Claude Code, which performed reverse-engineering analysis and authored the recompiler, runtime and documentation. The port runs on a custom C11 and SDL3 runtime and adds widescreen support, variable framerates from 30 to 144 fps, and modding support for music and cutscenes, while requiring users to supply their own USA ROM dump (SHA-1: 11f9e8204e484eab42181b210c9f214584be75bf) and shipping no copyrighted game data. It is tested on Windows with clang and Linux with gcc, with macOS untested, and lacks Wi-Fi, microphone and DS 3D engine support.

Evidence at a glance Loading source evidence… What was done Egg of Time is a native PC port of the Nintendo DS version of Chrono Trigger, achieved through static recompilation of the game's ARM9 code into C11. It provides widescreen support, high framerates, and modding capabilities while requiring a user-provided ROM dump. Egg of Time is a project that enables a native PC experience for the Nintendo DS version of Chrono Trigger by performing static recompilation. Rather than emulation, the project translates the game's ARM and Thumb functions into C code, which is then compiled into a native library. A custom runtime, built with C11 and SDL3, handles hardware-specific tasks such as 2D graphics, sound, and input. The project features widescreen support, variable framerates 30 to 144 fps , and modding support for music and cutscenes. Development was assisted by Claude Anthropic via Claude Code, which performed reverse-engineering analysis and authored the recompiler, runtime, and documentation. The project is currently tested on Windows using clang and Linux using gcc , while macOS builds are currently untested. The software does not distribute copyrighted game data; users must provide their own USA ROM dump to build the game locally. Limitations include the lack of implementation for Wi-Fi, microphone support, and the DS 3D engine. Further details on the architecture are available in the project repository https://raw.githubusercontent.com/power-pudu/egg-of-time/HEAD/README.md .
