When I did systems on the Lear, I had such a blast coding it. I had all these cool features, gauges that showed fuel bleeding, etc, etc. I had wing overheating features, alarms for everything, all this coding. And what happened? A million complaints. People freaking out, complaining, ranting, posting their rants, this doesnt work, that doesnt work when it actually worked fine.
Cold and dark flights are something of a mystery to everyone in the FS world. They all use it now, and yet cannot figure out why all of their planes cannot use a CD file from one single plane. (Settings for fuel and particular switches and valves are all stored in the save file. If you shut down in a Cessna 182, mixture off, fuel tanks off, totally different fuel selectors, etc, and you try to turn on a new plane with special coding features, none of that works. The one jet engine will not start or run properly because the Cessna mixture was (is) at zero setting (cold and dark) so that engine will not work, so its all Bill's fault because people do not understand how to use cold and dark files. (WHAT A NIGHTMARE THAT SUBJECT ALONE WAS!!!!!)
Then there is the reviewer at AVS that would email me 10X a morning with repeat questions. Always the same questions, questions answered in the manual and by me. Why cant I use my CD file on this plane? But why? Why do I have to use the switch in the VC instead of just using Control-E to start? (system coding).
I had people crying that their saitek buttons wouldnt work on my plane, they couldnt use it (system coding). People with 3D cockpits couldnt use it because their gauges worked with standard sim platform systems, not system coding.
So, you ask me for system coding? I laugh. The market isnt ready. They cannot read manuals.
One German reviewer went on to say how the various systems DID NOT WORK. lol... We all beta tested it, it was working fine, no issues, all functioned. I shot down his review with the TRUTH. His fellow reviewer went through and retested and sure enough, it was all working. Someone didnt read the manual.
So, if you want a F100 with system coding, go to PMDG or make one yourself. You deal with the people that refuse to read the manual, refuse to learn the system, the reviewers that make you look bad because they didnt want to take the time to read the manual and see how it REALLY works.
