Finally!
A complete collection of all the early emergent factions startpos.esf.
I know i would have saved maybe a dozen of hours if i had found a post like this one from the start, but here it is, i compiled all the startpos.esf files from Husser1TW's ETF mod and made a small .rar which contains only what is needed.
All you must do is extract the folder inside the .rar, then put the startpos.esf and scripting.lua files for the emergent faction you want to play in your campaigns/main/ folder and launch the game. Enjoy!
