well here more detail: open shipedit for eaw or op (the only differance are the weapons and adm), after the ship edit is on click on the file icon or open file and click on open, there open the shiplist (eaw and op are at the same place in taldren software inc for op or taldren for eaw), once its open beside the word class there tree icon, click on Add ship, there you chose the race and give it a name like CABR, then you chose the geometry, then you chose the UI for the ship, then you give it a full name and a class type, once that is done you give the year you want the ship to be aivalable during the game, the year 0 is early but you can have it a lot sooner by having the - before the number like -20 so your ship will be available and don't forget the number for the last year available in the general, now you add the spec, power impulse, ect, you have the weapons and hull/shuttle/crew, now that all the info are there you must save your data on the shiplist in metaAsset and in assets/specs.
if you still having problem tell me and i will try to help more.
