Hee-hee, yeah, that was my problem, trying to navigate thru all that. Your gizmo seems to do most of what I want to do (reduce radius of depth charges so I don't get sunk by one 8000 yards away, etc.), but as near as I can tell it don't convert graphics? Found another link for that, to an Nvidia DOS based converter. I'm an old DOS dinosaur myself, but the one thing I like about Windows is I don't get all the $YnT@X 3rr0r$ I used to get with my hunt 'n hammer typing style.
Better program for converting DDS to TGA, BMP, or whatever is convim:

Visual basic interface, lot easier to use.
