:-zhelpHello, I downloaded an aircraft that included a fuel guage that isn't working correctly. It displays 0% thru 100% fuel in the upper 1/10 of the scale. It is NOT an "xml" file, it is packed with other guages in a .gau file. I would like to fix it because it looks good and is lighted correctly to match the other guages.Is there a program available to edit the older .gau files?please email me if you'd like [email protected]

No, there is not. Compiled gauges (.gau) cannot be decompiled and edited. At most, one might manage to extract a bitmap, make a small change, and reinsert the bitmap into the gauge...While there are some tools that will "decompile" to an assembly language level, that'd be completely useless for all practical purposes.
