## What was done

Precursor is an unofficial, non-profit port that enables the Jak and Daxter trilogy to run natively on Android devices. It utilizes the OpenGOAL project's codebase, adding an ARM64 compiler backend, OpenGL ES 3.2 rendering, and a dedicated launcher for asset preparation.

Precursor is an unofficial, non-profit fork of the OpenGOAL project designed to run the Jak and Daxter trilogy natively on ARM64 Android devices. The project implements an ARM64 backend for the GOAL compiler, C++ to GOAL call bridges, and a renderer adapted for OpenGL ES 3.2. A custom Android launcher handles ISO validation, asset extraction, and compilation directly on the device. While all three games boot, the project remains experimental and unverified end-to-end. Jak 1 is the most advanced, featuring functional gameplay at approximately 60 FPS. Jak 2 supports basic navigation and collisions, while Jak 3 currently stalls at a white screen after the first cinematic. The project is developed with AI assistance from Claude (Anthropic), which contributes to code, diagnostics, and documentation. Commits authored with this assistance are marked as (AI-assisted) and include a co-author trailer. Users must provide their own legally purchased game ISOs, as no assets are included.
