How do ypu mod with no shared files?

How do you mod whenever the 2 subjects share no same file i try to inject and it says not found this is urgent as i am making a VERY BIG pack so if you can help post quickly

...wait what?


you mean..how to inject a file, that isnt in the original rez file?

you can't. and there is no reason to, because if there wasn't already a file with that same name in the rez file then injecting that file wont affect CA at all. simply because CA only uses files it was programmed to, extra file wont affect it at all.

Yeah but is there a way to make like the M9 into strider i know its been done but i dont know how
