It would be a bummer to create such a large (4MB) file from scratch, unless someone has complete knowledge of how the save data is laid out.
How did you guys do this?! I never manually hacked AC:WW, but I tried messing with the AC:CF data, and I could do anything without the data corrupting. I think it's because of some data hashes (I found a few 32-bit hashed, presumably at each resident's prefix). If you guys could create some low-level documentations, that would be amazing; I'm really curious!
Thanks for the killer app.
