without developer it's not so easy. if someone want to mod the game, nessesary to buy the game. anyway... there is different between the 1.16 reg and the 1.02 ent. files (as you said)
I downloaded the mods. Tthere is a SSD (Sovereign Star Dreadnought) and an Executor (Executor Star Dreadnought) ship. Which do you want?
As I see , the Requiem mod is for Entrechment, it means, there is the entity.manifest, and you should update that with your new entities: ships, abilities, squads and fighters (and raise the entityNameCount). The whole Requiem mod is in binary. I can't use the converter (I have vista x64), to convert the files into txt so I can't modify them. Maybe you have another mod (in txt files) or you did convert them. Right now I don't really have time for doing this for you (i have exams) and I use entrenchment 1.01 (I don't want to patch my game, we have our own mod in 1.01).
As I see the Executor is a Capitalship, and there are lof of new stuffs in it, what you should copy to the new mod.
Clone an existing capitalship.entity from Requiem, add that ship to your player.entity (capitalShipInfo) and update the entity.manifest with that ship. Now you have two same ships in Requiem.
Copy the mesh and shield (SUPERCAPITAL_IMPEXECUTOR and SUPERCAPITAL_IMPEXECUTOR_SHIELD) into Requiem and change the ShieldMeshName and the MeshName for them. With this step copy from "NumWeapons 3" untill "m_weaponIndexForRange 0"... and set the TargetCountPerBank. You have to copy over the related textures for the ship, the related particles and sounds for your weapons. After that you should have the Executor ship in your game with mesh, shield and weapons.
Copy over the new abilities (ABILITY_SATURATIONFIRE and ABILITY_FLEETCOORDINATE) and the buffs for them (BUFF_FLEETCOORDINATE, BUFF_FLEETCOORDINATESELF and BUFF_SATURATIONFIRE), update the entity.manifest with them. Place the the abilities on your new Executor ship. (Check the abilities' name and descString ID. The FLEETCOORDINATE is using TARGETINGUPLINK, this is the original too. The SATURATIONFIRE is using new name, you should add this to your English.str as I said previously, the VOLLEYFIRE is original).Try if it's working now.
Copy over the new squads and and fighters, check there names and icons. Check the related fighters to the squads (name, pictures, weapons, mesh+shield maybe). Update the entity.manifest and the English.str if it's nessesary.
Now you can prettify your capitalship with bombing, engine, set the new movement values.
Sorry, I was a little bit sloppy, I didn't know that you want a Capitaship, and the mods are for different pack (original and entrenchment). And I also didn't know, there are many new effects, sounds etc. in it.
That's all I can help you. Good luck.
