File is here. (https/nofile.io/f/rOFjwqmyucr/GSX+CS757+config+files.zip) Change the name to gsx.cfg and then move it to the simobjects/airplanes/cs757 folder. Or manually transfer the numbers over. They should line up pretty well. As per cues, the service doors R1 and R3 are set to no cue unless someone can figure out how to set up custom code for it.
