Change already existing Wolfpack scripts without touching standard scripts I guess you always want to keep updated to Wolfpack script changes (due to bugfixes etc.), but also implement your own changes in standard scripts. So if you edit the standard scripts, there'll be probably an problem everytime you try to update your scripts by using SVN. And to implement these updates in your heavily costumized scripts by hand is always difficult and takes much time.

Clients For testing purposes you should use the OSI Client at the moment. OSI Client You can run the original (OSI) client under GNU/Linux with the help of Wine (see ). There was a download called uoml_setup.exe called Mondain's Legacy which contains Client Version 4.0.11c (Patch 0).

If you wish to use MySQL, you will also need to download MySQL itself before compiling, since it comes with header files and libraries required to activate MySQL support on Wolfpack.

Convert sqlite2 to sqlite3 format Since version 12.9.14 (SVN revision 6568) Wolfpack changed it's default sqlite driver to Sqlite3. Among other changes, this has provided a huge performance gain over the old system. It now takes 1/3 of the time, or 300% faster to save a world with full inserts (which is the worst case scenario). Unfortunally this change requires a manual step to convert from the old format.
