Can someone provide me with a comprehensive guide on how to replace the standard GPWS calls with user-defined ones? I rendered some new calls and replaced them in the airplane file, but it's not working when I try it in-game.
With the SDK tools you can convert your .wav files into .tsb files. Just make sure they have the same format as those provided in the example DR400 aircraft (Mono, 22kHz)
