I want to know how to replace some of the major and minor races with some of my own custom races I'm developing. What files should I be looking at? For instance, I wanna change their image and race logo. Also their tone, for instance the Thalians seem to roll the SSSS alot. And is there a way to replace the standard ships (example: Battleship design) with a custom one i made in the shipbuilder so that race would always build that ship when it wants to build a battleship? I want to do all this using the mod folder so I don't mess up the original game.

Eventually, I want to use Galciv 2 to tell a different saga.
