Messing with the scenery.cfg file has nothing to with and will have zero effect on whether GSL scenery objects show up or not. Nada. What fooling with the scenery.cfg file will affect is whether the airfields themselves show up- the runways and any API Macros, i.e. "static" objects you may have added when building an airfield in FSSC or similar scenery-building program. But it will have zero impact on which GSL objects show up. Trust me on this.
Just out of curiosity, to make sure we are both on the same page here, what do you refer to, what do you mean, when you say GSL? What sorts of visual things in the sim do you think of when you think of GSL scenery? Please bear with me.
You understand that GSL "scenery" objects exist quite independently from any thing that is handled...
