Troubleshooting for Dragon Ball Online server owners across 2.0 and 0.60 - connection errors, database problems, client crashes and configuration mistakes.
Most problems posted here come down to a handful of causes: the client pointing at the wrong address, a database the server cannot reach, a missing runtime library, or a port that was never opened. Search before posting - the same Dragon Ball Online errors come up often and usually already have an answer.
Dragon Ball Online (DBO) private server and emulator work builds on the 2014 public source release, the Daneos server files and AKCore, whose One Click Repack skips compiling, with the external IP set in server.ini; DBOG 2.0 went open source in 2020. Sources compile in Visual Studio 2010 Ultimate with Boost 1.55.0, DirectX SDK and x86 MySQL C/C++ connectors, on MySQL under XAMPP or WAMP with Navicat, split into auth, character, chat, database and game servers. Clients include Korean 0.50.9, 0.59 for the public source, and Taiwan 1.69, which wants the 9001 memory patch or Themida-unpacked DBOG.exe. Tools unpack .pak, extract RTP files and decode EDF tables to RDF.
