@realman543 Found the things I was after and extracted everything else, plus some extras. Turns out that repo includes Horizons.
And rulebooks.
Also for some reason basically everything was duped, including card backs. As in every major power had two front sides and two back sides, resulting in 4x as many images as cards, instead of 1x + 1 for the back.
Shaved off an entire gb by fixing that. And that was after I had already cut dupes of the character mats in initial pass. (Except one that I missed.)
