Launcher v0.2.0-rc9¶

Released 2026-10-21.

Settings¶

Game settings read as words: the aspect as 16:9, levels as Off, Low and High, and no internal names.
A game's Display tab sets a frame limit, anti-aliasing and upscaling, each with a picker of its own.

Interface¶

Text across the launcher is larger, and card titles read above their rows.
A faint seal sits behind every page, the profile menu opens on hover, and the bar names the runtime.

Security¶

A runtime file the store says Phaethon signed installs only once Windows verifies its signature.
The setup's license forbids reverse engineering the launcher and removing its notices or signature.
The launcher carries the runtime license's new terms and asks to accept them once they take effect.

Fixes¶

Changing Texture filtering, Actor detail or Present on a shipped preset no longer crashes.

Phaethon is a hard fork of OpenGOAL's jak-project. Naughty Dog made the games; you need your own copy of each. built from the wiki · 4 Nov 2026

Built with AI in the loop. Phaethon uses AI assistance for speed and accuracy, and holds it to the same bar as every other contribution: every change is read, tested and checked against the console before it lands.
