The PSO2 Tweaker is a replacement for the normal PSO2 launcher, used to update, patch, and launch the Japanese version of the game. The Tweaker adds several options to the game, such as the option to automatically download and install the English patch and any updates to it, configure your game settings, update your game quickly, and much more!
