I need to look at the decision making logic of a panel guage which exists for use in an "in simulator" MSFS aircraft panel... so that I can write a stand alone compiled VB6 program to drive some simpit hardware so that the "real" warning lights and such come on at the same time that the stuff in the sim does. 

The problem is that the variables for the decision logic for the GPWS gauge that I am working on are not directly accessed via FSUIPC offsets but involve logic applied TO FSUIPC variables like the vertical speed, altitude, flaps condition, and so on.

How do I disassemble a standard gauge file?

best,
