Actually Nole, this is the best place for that question. On the face it may appear to be Fox4-specific, but if you peel back the surface you can see that this is really a general CFS2 question pertaining to setting up any new theater install, which most of us old hands have done to some extent. And this type of question has come up in this forum many times over the years.
Stick, all the above technical replies are spot on for setting up your new Korea install. I personally removed all Japanese a/c with the exception of the Zero, to which some NK or Chinese prop add-ons are aliased in sound and panel, until i can set them up with alternatives. I also removed the Devastator, Dauntless, B-25, P-38, P-39. I kept the B-24 and Wildcat (for sentimental reasons), and i also kept the Hellcat and Corsair because they both continued in limited US service even beyond the Korean conflict.
