Full Credit to Knusprigvej for his work on the 777-200ER compatability mod, this has just been adapted and modified to work with the 777-300ER and 777F addons.
This addon now includes an optional download which includes the excellent CS 777 Upper Eicas Mod by jdb preinstalled, full credit to him for his work on this file.
Installation (Please read!):
Download and install Captain Sim's 777-200ER, 777-300ER or 777F
Download the 'Main File' and 'Salty Compatibility with Upper EICAS' mod from this mods download page.
Install both folders into the community folder :)
Black Screens Issue:
This seems to be causes by a mod incompatibility with the YourControls addon, remove the YourControls addon from the community folder and it all works for me.
This mod does NOT contain any files from the Captain Sims 777.
This mod is not supported by Salty Simulations or Captain Sim.
