The Zenith of Fallen Empires: RS/SSx6 + ASB is a compatibility patch made for ZoFE users who play with both Amazing Space Battles and Real Space: Ships in Scaling (Hard). This patch does a few things: first of all, readjusts ZoFE components' weapon range to fit with Ships in Scaling, enable ZoFE thrusters to work with cruising speed, while also provide a better experience when used with ASB, namely by keeping some ASB ship behaviours and defines so they are not overwritten by Real Space, and vice versa.
There is a load order to this: ASB needs to be put under RS and Ships in Scaling, and this patch needs to be under ASB. As for ZoFE itself you can put it above RS.
Of course more feedback and recommended tweaks are welcome since this is my first time doing a 3-way compatibility patch, so, a lot more variables are at play.
tl;dr You really should've read this.
