FS2004/FSX BlackBox XML Gauge Debugging Utility. BlackBox constructs an xml diagnostic gauge that can be used to display in readout form the numerical or string values of all or selected A:, E:, P:, L:, C:, G:*, and @c and @g macro (related to the FS2004 or FSX gps module) variables of the gauge you are editing/building. It can display important parameters such as boolean, L: and A: variables that are not often displayed directly by the gauge you are building. As such, it is very useful for debugging xml gauge logic; you can see what the variables are actually doing as MS Flight Simulator flies. By Robbie McElrath.
