As you know, the knobs (SPD, HDG and ALT) in the default FSX A321 autopilot are clicked to activate the function, and then turn a shade darker - but only a little, and really difficult to see the difference at a glance.The images for these knobs must be in the Airbus_A321.cab file in the Panel folder, and there appear to be three or four .bmp files for each knob (off, off/night, on, and on/night).Is there someone out there who can extract (or already has?) these images, change the colour a bit (maybe white for off and black for on, or at least clearly different), and then fit the .cab file together again?!Incidentally, the default A321 appears to share this file with the iFDG A320 and the Project Airbus A318/A320, so these freeware aircraft ought to be able to benefit, too.

You can extract the cab yourself using the same app you use to unzip downloads.A .cab is nothing but a compressed folder and the sim does not care if the gauge and it's bitmaps are cabbed or in a normal folder.Once extracted, you can edit the xml and bitmaps, after backing them up, of course. If you want to recab it, you'll need to have the SDK installed. Cabdir.exe will reside in SDK\SimObject Creation Kit\Cabdir SDK.Copy the folder with the .xml and .bmps to that folder and drag it onto Cabdir.exe.The end result should be found in C:\Users\User Name\AppData\local\VirtualStore for Windows 7, other OS are similar...Don

Don, thank you very much. I was indeed able to extract the files from the .cab folder - that's how I found out which ones ought to be changed in colour.I do not have SDK installed. I take it from your reply that the folder doesn't need to be cabbed again. Would that mean leaving all the files as separates within the Panel folder under the aircraft in question? Regards, eskil

No, you leave the .xml script(s) and .bmp files in the same ..\FOLDER to which it was extracted. That ..\FOLDER remains within the ..\Panel folder: ..\panel.......\gaugename............yyy.xml............zzz.bmp............etc.
