Important Notes


※PSOBB is a Windows Only game, and has been tested running on Windows Environments from Windows XP all the way up to Windows 11. While it is possible to install the game in other OS such as MacOS or Linux with solutions such as the Wine Wrapper, Proton (Steam Deck Users) or via Virtualization operation is not guaranteed and we cannot give support to those platforms.


※On Windows 10 and Windows 11 it might be necessary to run the game without Full Screen Optmizations to ensure optimal operation in FullScreen mode, to do so navigate to the root of the game at C:\SchtServ\Phantasy Star Online Blue Burst\ and right click on the "SHPsoBB.exe" and enable the following setting: Disable Full Screen Optimizations.


※If the game fails to run on the first try, please select the OPTIONS from the launcher and adjust the Resolution to at least 1280x920 and Color Depth to 32 bit, set Graphic Setting to High-End and enable Window Mode.
