Rise of the Crime Lords is a mod that adds the Black Sun Syndicate and The Hutt Cartel as playable factions along with multiple additions to the original ones as well as adding some new unplayable ones.
You can now progress tech levels 1-5, both Black Sun and the Hutts by Establishing levels of Black Market connections (Empire tech progression was the only one that could be cloned to those two factions.)
Nice, I really like the icon you added for it
