Most visitors to this page will be looking for our PSO2 custom launcher, the PSO2 Tweaker! The PSO2 Tweaker is a replacement for the normal PSO2 launcher, used to update, patch, and launch the Japanese and Global versions of the game. The Tweaker adds several options to the game, such as the option to automatically download and install the unofficial English patch and any updates to it, configure your game settings, update your game quickly, and much more!

.NET Framework

The tweaker requires at least the .NET Framework 4.6.2 to run in Windows. You can grab the installer for that here.

In addition, the Tweaker also supports some launch flags. You can use these by making a shortcut to the Tweaker. Right click on the shortcut and hit properties, then add the flag at the end of the "shortcut" box.

For Steam, add the PSO2 Tweaker to your library, then right click the game in your library. Select "Properties...", then "Set Launch Options...", and put one of these flags in the popup window.
