There's a version that adds only British and American ships but no neutrals. It's called "Interim Beta" or something like that.
Odd, now when I click on that link it loads the main page but won't let me into any of the directories.
I checked on Jim's Gamefront page but didn't see any MFM stuff there. Can't find it in downloads either.
@Phoenix3000: I think I have what you're looking for, I'm trying to upload it to Gamefront now. I'll post a link if it works. I don't have an account there and it's prolly a big file, so I dunno.
