Unreleased¶

Jak X¶
- Jak X imports from its retail disc through the launcher.
Launcher¶
- Importing a folder that holds a different game stops with a clear error.
- The game's reports to the launcher no longer stall after one of them fails.
- Only your own account can read what the game reports to the launcher.
Delivery¶

v0.1.0-rc3 - 2026-09-25¶
Launcher¶

Games¶
- Game loading follows the original console more closely in all four games.
v0.1.0-rc2 - 2026-09-24¶
Delivery¶
- Nothing changed in the games; this candidate tested how releases are published.
v0.1.0-rc1 - 2026-09-24¶
Games¶
- The first Phaethon release: Jak and Daxter, Jak II, Jak 3 and Jak X: Combat Racing as native ports true to the originals.
- A remastered preset sits beside the original look and keeps its own settings.
- A debug window can be opened at startup.
- Every Windows release comes with DLSS and FSR upscaling built in.
Launcher¶
- The launcher installs the runtime, which never includes anything from a game disc.
Delivery¶
- Each release comes as a single download.
Phaethon is a hard fork of OpenGOAL's jak-project. Naughty Dog made the games; you need your own copy of each.
