I think just about everything is replaced, which is from alot of mods implemented together.
What are your specs. There are some exceptions. On my old comp with a 2.6ghz proc, 1GB Ram, and a 128MB gfx card, it ran swell. The only problem it had which I think was RAM related(not enough), was when I put more than about 200 units on a custom battle it would crash. But I have tried it with many more soldiers on my new one and I have not had a single crash.
It goes into the FFSX folder. And I will remind you that I put the Berghoff wrp files into the world folder, with a zip of the originals in case you need them.
I will try to get some later then. :)
Basically, it is a huge addon pack. I made a small addon for FFSX that did some big chnages to the config file but I decided not to implement it just yet. As of right now, I have not impletement any of the new features into the campaign, but when this mod is in its final form, I expect to release several large campaigns, such as a conflict between Everon and Nogova, with both sides being playable. :bounce3:
