I didn't like the default ships in Starship tycoon, so I opened up and edited the Ships.dds file on my game. I've already tested the file on my game, and it works great. I'd like to put a link up to it on the site for those who might be interested, but the images I used are copyrighted and I wanted to make sure that it was cool with the admin before I posted the link.
I updated the ships so they are the Wolverine form "Space: Above and Beyond", a Narn Heavy Cruiser from "Babylon 5", a Constitution Class ship from "Star Trek" (the original Enterprise), & the Prometheus from "Stargate: SG-1". The Narn Heavy Cruiser flickers a little bit on screen, but the other three work flawlessly.
(I do have to say, though, that the extra ships in the Ships2.dds file are totally cool!)
