# Precursor: Android ARM64 port of the Jak and Daxter trilogy

> Precursor ports the Jak and Daxter trilogy to Android ARM64 using OpenGOAL's recovered GOAL code and tools. It adds an AArch64 compiler backend, C++–GOAL call bridges, an OpenGL ES 3.2 renderer, and a phone launcher that extracts and compiles game data from the user's PS2 ISO. The author reports that all three games boot on a phone, with different portions playable.
