The "Captain Sim B777/B767 - Salty Compatibility with EICAS Mod" by Masterrob is being updated almost on a daily basis. He is doing a great job of finding issues and correcting them as he can. If you run into minor issues once you get these downloaded (APU not starting, dome light not working, etc.), check the comments section for this mod on flightsim.to and you will most likely see that he is aware of it and working on it.
