Well if you were to schmooze someone over at SCHT hack to get some server code. Hell, I don't even think their servers are up anymore, so it may be work investigating.
Edit: It looks like their hard drive in the server hosting PSOBB went down, and they never took a backup as of 7/30/2015. I think they're still trying to figure out what they're going to do although the community is overwhelmingly saying they would like to have a fresh start.
