Settings

  • With Remastered on, a game's settings tabs edit its remastered settings, not the retail ones.

Interface

  • The Phaethon mark replaces the JAK lettering on the icon, the splash, the sidebar, About and Home.

Install

  • The setup offers a Phaethon folder in your user folder, which needs no administrator rights.

Security

  • Settings and the setup have a Send crash and usage reports switch, on by default.
  • A launcher crash sends Phaethon a report with no account or PC name, unless reports are off.
  • With reports off, your play sessions are not sent to your Phaethon account.
  • The Account page, the setup and About say what the launcher sends.

Fixes

  • The import bar moves while a game compiles.

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.
