You are remembering that a little wrong, Sonic made Ship Pack 1 and 2, not DC.
DC or Bloodstar released a couple small 3 ship sets. Sonic was more prolific with maps and dozens of ships.
When I made service bay, I tried taking the most popular parts from all the previous packs and combining them.
In some cases adding ships to the campaign can break the flags that allow you to progress too, or make it crash, I would consider all mod packs fairly buggy with the campaign.http://dropcanvas.com/y078g
You can get both of sonic's packs there for the next 6 hours (link expires), our ability to host files is sort of limited currently.
As far as old files go, I have all of Sonic's files, most all of everything DC released, but not his private stuff. Blood's ships I have.
Razor's files mostly were lost to a hard drive dying. Slippster's released stuff on his old site I mostly have from the later years.
There are some unreleased map editors that Deckor and Mystica have, but they aren't letting them go.
Shadows Lament from when I found her at Star Citizen, doesn't have anything anymore.
There were a few people that had mod tools or cheat tools that gave me their stuff.
So bottom line is that I'm the last bastion of Tach files. As far as what was released to the public, I have what remains, if people are looking for it.
