Welcome to the SBOL Project site.
Back in 2003-2005 Genki released 首都高バトルONLINE (SHUTOKOU BATTLE ONLINE) for PC. Unfortunately this game never made it outside of Japan and was short lived. The goal for this project is to enable fans to play this game.
With the official servers being shutdown long ago the only option is to develop a private server. However with no packet logs of the game, development of the server is being achieved by reverse engineering the game client (which making development extremely time consuming).
If anyone would like to contribute to the project please get in contact.
