From what madmax said you did not want to muddle it to much because the mod took so much from TMO and other mods that it didn't need much. It was a conglomeration of several different mods that were all made compatible with each other and then put all into one mod so you didn't have to run so many together but a single mod to rule them all ... so to speak.
The original thread had over 52 pages of discussions :
FALL OF THE RISING SUN
(EDIT)Going back and reading it seems the latest version of FALL OF THE RISING SUN incorporated the updates.
I know there were at least two updates both done by EXE files so you didn't even have to add a mod you simply patched the original. There was a lot of work put into making the ships look more like what they were in real life as well and performance issues.
