Nice Idea, but i think, this is a war, you can't win.
I just tested the 1 and the 4 (that don't work) and this engine are to old for FFB in a DD. By me side, i think 4 stars are 3 to much, but I don't want make you life harder. If you release a better version, i will sure test it.
Thank you for your work and i wish you find a way, that we have all fun with that old games!
