Cannot get Hi-Res Mod to work

[LukeFF]

I've installed the MS Application Compability Toolkit and installed the two d3d9 files as described, and I've followed the instructions exacty as they are described in the Community Manual. Even so, the resolution looks just the same as before. I'm running XP SP2, Nvidia 7800 GT, and am trying to run the game at 1600x1200. Is there something I'm missing to get this operating correctly?

I also had problems with 1600 x 1200, so switched to 1440 x 900 and saw a significant difference.
