Silly question.
How can one go about changing David Brindley's GP7 so it uses the GP9 sounds instead of the default engine sounds? Is it as simple as swapping out the provider/package, etc? Or something more technical? I don't have RW_Tools as of yet, so I use Notepad++ which is perfect for just swapping some lines out with others.
I ask this because the GP7 and GP9 used the same prime mover more of less (EMD 567B for the gp7 / EMD 567C for the gp9). Only difference is the horsepower (1500 and 1750 respectively).
