Jak 3 Arrives on PC via OpenGOAL, Completing the Full Trilogy Port

The OpenGOAL team picked April 1, 2025 to drop its Jak 3 beta announcement, then immediately clarified: not a joke. The project, which reverse-engineered the custom programming language Naughty Dog built for the entire Jak trilogy, had finished enough of its work to make Jak 3 playable natively on PC for the first time in the game's history. With that release, all three entries in the Jak and Daxter series became available on modern hardware without an emulator.

The technical hurdle at the center of the project was GOAL, Game Oriented Assembly Lisp: a custom Lisp-dialect language Naughty Dog created exclusively for Jak and Daxter: The Precursor Legacy, Jak II, Jak 3, and the spinoff Jak X: Combat Racing. Over 98% of each game's code was written in GOAL, a language that was never publicly documented and had no existence outside the studio. OpenGOAL describes the effort as "primarily an exercise in curiosity," with modding support listed as a secondary goal.

Jak and Daxter: The Precursor Legacy was the first to reach a polished, complete state, followed by Jak II, which entered beta in October 2023. Jak 3, Naughty Dog's 2004 PlayStation 2 conclusion to the trilogy, became the final piece when it entered beta in April 2025. All three games are described as "feature complete and fully completable." Jak II and Jak 3 remain in beta due to lingering audio bugs and minor graphical issues, neither of which prevents players from finishing either game.

The port runs as a native x86-64 binary on Windows, Linux, and macOS via Rosetta translation. The OpenGOAL Launcher, required to install and run the games, also functions on Steam Deck in Desktop Mode. Players must supply their own legally purchased PS2 disc for each title; the project distributes no game assets.

Quality-of-life additions include high-resolution and widescreen display support, high-FPS gameplay, and a full modding ecosystem. The community responded quickly: a handmade HD HUD texture pack for Jak 3 appeared on Nexus Mods within a single day of the beta going live.

Jak 3 originally launched in North America on November 9, 2004, published by Sony Computer Entertainment. Mass Media Games later brought it to PlayStation 3 in February 2012 and PlayStation Vita in June 2013 as part of the Jak and Daxter Collection. Neither release nor any official platform since ever included a PC version.

OpenGOAL has said it is "unsure" whether Jak X: Combat Racing will be its next target and currently has no plans to pursue it. The project's full codebase is open-source and publicly auditable on GitHub.
