Wasn't Allied Force a community effort because Falcon 4 was just about the most horrifically buggy game ever, but the devs wouldn't support it properly?
Right - as I read in a review, "Falcon 4.0 pushed the envelope and the envelope pushed back". But Lead Pursuit has done an excellent job of making it very stable, so the Allied Force product is much, much better in that regard. There was a specific note in one of the patches that mentioned support being added for 5:4 aspect ratio. So I get the feeling that there won't be anything I can do myself (not that I have any experience at this sort of thing anyway).
