Hi w777chey, I have updated my Mass Effect 3 hub. I cannot repost the entire section here, so I will just post the introduction of the section:
How to Increase EMS with Save Game Editor
This section of the hub will help those players who can not raise their EMS above 5000 (because they cannot play multi-player, are too far into the game and do not want to restart, are lazy, etc). The entire process will take only about two minutes. Remember to back up your save just in case you mess up (better safe then sorry). As a side note, you must have a program that can open zip files (such as winrar or 7zip).
The hub is located at: https://levelskip.com/rpgs/Mass-Effect-3-How-to-ge...
and the hub has step by step direction on how to use the hex editor to unlock all endings by changing your EMS score in your save game file.
