I have been able so far to create a star system containing a homestar, homeworld, 1 uncolonized planet. I mixed and matched some of the continent graphics for a unique homeworld appearance. Now the only way I have gotten it to work as a selectable starting system is to add in the custom system info into starsystemdefs and use the replace method in my my docs mod folder. If i try to use the add method by adding a suffix to starsystemdefs containing only the custom system info i get CTD.
So is StarSystemDefs locked or hardcoded to where the add method will not function, and if so are there other xml's that are similar?
