During my research i found out that CFS2 is basically FS2002, but with differnt content, enginewise. At least I think that is what i read...i may have it wrong and it maybe FS2000, but i did read that it was a parallel to one of the FS's. Others may know much more and will hopefully post as i am very interested in this too, i hope to help create some more complete cities like London and Berlin and Rome and Paris with more detail but it would be great to be able to work with some of the great things that have been made for FS2002 (with permission of authors of course) ...so i am very interested in this too. I found a wonderful older add on by John Russell for the UK that creates all the major railway stations for London, Derby, Sheffield and working trains in modern livery, it is for FS2000 but i have the structures working in FS2004 and so hope to move it back to 2002 and hopefully then with a skin change, if i can get ahold of John, to give us steam trains of 1940's that may even run, for ET0 ... i am studying how the file system works but it looks similar to CFS but i am not sure yet if it is possible to convert the .R8 and the
.0AV and .PAT texture files into .bmp
