How do I do that? Simply remove the old Runewaker folder and replace it with the new one?
Im doing it at the source code level because there are several thing i dont like about the new build, dont get me wrong, im very grateful for the release. I just am used to a certain file and code structure
I recommend doing what i am doing, im combining my 6.4.2 with 6.5.2 so i can keep my changes and database format without changing the entire thing
