Usually when I release some of Mackie's ships, I use Mackie's renderings instead of some of my own because Mackie has them already up on his site (so I don't have to take the extra time to render, and the extra space for pictures).
But all these ships now have the class name as their registry name.. so there is the U.S.S. Ironcross, the U.S.S. Flash, and the U.S.S. Wickerman. I replaced the names and registries on every texture that came with the ship.. even on textures that may or may not be used with the new ship. Just C'sYA in case you *think* a texture isn't used, and it actually is.
I also *try* to do some basic hp/dp's so that everything isn't firing or projecting from the center of the ship. They aren't always accurate, and I'm reasonably certain that they're not.. but I include them so that later, they can be moved into the right positions for each ship. I only know for certain what one HP does in reference to SFC anyways (wasn't that much of an interest when I first started modding, though I'm looking for more info on it now.)
If anyone has a list that said HP1=Heavy Weapon, HP12=Phaser or some such that went through all the possible HP's you'll find in SFC 2 and 3, that'd make me a happy camper to get my hands on.
