Thanks for the reply. There seems to be some other minor differences between the formats (an extra wstring in the header in fos files for example) but yeah, luckily they're mostly similar. The bad news is that ACHR records in ess files have practically no documentation at all so I'm going at it completely blind. Still, I'm making progress, albeit slow progress. Any clue as to where I could post my findings though? I really don't want anyone to have to go through all this again if possible. The Fallout Mods wiki has a page on FO3's save format but they don't have anything on FO4 yet and it doesn't look extremely active (at least not wrt newer games).

I'm working on a tool to copy face/body data from one save to another (this one) but it's a pain trying to decipher the format manually. Is there any documentation for the .fos save files (or Skyrim's .ess files for that matter) besides UESP? Or any place I can help out and add what I've found out about the format? More specifically, it's the player's ACHR record I'm trying to parse since for some reason the body's skin color is cached there together with some more face related data.
