Hey Pathfinder sounds like a real good setup. Since the Boards had apperently taken a nosedive recently I tried to use your advise and Imperator Fyron's modding tutorial to get those darn Repair ships set up.
As you suggested I copied the file of the medium and large repair tugs and renamed them so they can use the Cotton's and Majestic's bmps. I'm hoping I did this right all I changed was the first 2 lines (Name and short name) from medium and large repair tug to medium and large fleet tender. I also changed the bmp name so that these new entries use the Cotton and Majestic bmp and not the transports. Everything else I left the same though, Code and every other line.
I hope you don't find this too disappointing but as I was toying around with the Tenders I kinda got inspired and rearranged the EA shipset for myself, here's my new list:
Baseship: Victory
Dreadnought: Warlock
Battleship: Omega-X
BattleCruiser: Omega
Heavy Cruiser: Nova
Cruiser: Tempest
Light Cruiser: Hyperion
Heavy Destroyer: Saggitarius
Destroyer: Equador (that's your current Cruiser)
Frigate: Artemis
Corvette: Olympus
Escort: Tethys
Medium Repair Ship: Majestic
Large Reapir Ship: Cotton
Tiny Transport: Iron Side Crew Shuttle
Small Transport: Skylark (Your current Escort)
Medium Transport: Kneale (Your current Large Transport)
Large Transport: Asimov (The unused ship in set)
I kept the Carriers, stations, troops etc the same. But I got "inspired" so I made some of the new ships you see up there, lucky for me all of the other sizes (beside the new repair ships) were already in the vehiclesize.txt. I know there is some AI file I have to edit for the EA to use all of these as well but I don't know what file and what to change (since I play EA it isn't a necessity for the time being). So what do you think? Any comments, suggestions, flying cabbage?
I also incorporated the Brakiri ships I made, and replaced 2 of the Drazi green ships with a couple of Drazi ships you have in the generic race folder.
The next thing I will tackle though wilkl be those Minbari Transports, having the Centauri Carrier there is just disturbing.

For the small transport I was thinking the non-combat Flyer, for medium maybe the Blue Star since they have the WS, and for the Large Transport I think the trasport from the movie In the Beginning. Any ideas?
