Case study

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.
