As for getting the SVN to work for you see this post: http://forums.civfanatics.com/showpost.php?p=11736625&postcount=6
And while it Is possible to have more than 50Civ.dll the 32 bit game engine of CivIV/BtS would choke on it. Not recommended unless you are an accomplished C++ programmer and have Lots of time to get around the game engines limitations. Koshling talked about it before in some C2C discussions on this very subject and he runs his on Software Programming business. FYI Koshling is the programmer that developed Max Compatibility Save format, Viewports, Graphic paging, and kept C2C's AI afloat during the last 20 versions while the content mushroomed.

How backwards compatible is the SVN? I don't want to lose the game i'm currently playing.
