They're all DS compliant in that list. I used to have more, like an unaltered release version of DS, different particle effects, and even more sounds, but each game update I lose a few and don't bother to update them. They've all been posted here, all of them except the modified flagship, which is me just toying with making capital ships have to be researched before you can use them, and the meshy stuff one... That is my own personal not to be released Frankenstein experiment for my amusement, because I made it all work out like Sins meets the 60's so everything is psychedelic and distorted and trippy as hell and I play it when some drunk ass or high as hell fool crashes on my couch and I don't want to throw them out in the middle of the night.
Went looking for them, here's Boshimi's Multiple Stars mod: https://forums.sinsofasolarempire.com/348205
And the flagship mod is here: https://forums.sinsofasolarempire.com/335474/page/183/#2914326
And the Mass Effect sound one can't be downloaded anymore, though hooahguy probably still has his files uploaded somewhere. (though in it's state that I have it actually is a step back from DS, but that's just my opinion and I do run it from time to time just to mix the sounds up, so bug him for updates if you're really Jonesing for it.)
