Ok, here's the link to the mod:
https://www.dropbox.com/s/eorq03c3k3mpv32/dstech.zipI've changed ds_ship_tech.java because it included one line which made Starsector crash and I changed the sounds of most weapons due to some sound files missing.
I'll do another post on how to get this to work with Exerelin but first I'll ask the authors if they're ok with it.
It's no magic, if you can't wait just follow the instructions on the Exerelin mod page on how to integrate mods into it.
I don't take any credit for this mod I merely updated it a little.
All credit for sprites and code belong to DMSK2.
Cheers
