Custom PSO2 Patcher

Simple patcher for Phantasy Star Online 2 that supports alternate mirrors and can pick up where it left off.

How to use


  1. Import project to Eclipse
  2. Run jp.pso2.gui.PatcherUI


Download precompiled packages from github

Mirror hosts:

Download the jar-only package from github, use the following command-line to begin mirroring

java -jar pso2-patcher.jar (path-to-save-to) (mirror1) [mirror2] [mirror3]

You can add as many mirrors to sync with as you want, but they must all match their version.ver files for the sync to run at all.

Warning: PSO2's total installation is about 5GiB big as of this writing, so expect a lot of bandwidth usage even with a small number of users if they are going to patch straight from install.

Something went wrong with that request. Please try again.
