Well, so much for that theory. I checked SO in software mode (shudder), and found that 903 is most certainly not used. Unless... unless the hardcoded version of 903 is different to the MAT itself. The cockpit components did look slightly different in software mode, but whether they were a different file or not is difficult to tell. At any rate, this is worth experimenting with... we need to confirm that HARD is indeed soft, so we can ignore it .
