> Just read you guide to adding an icon, everything worked fine until I got to the last bit. How do I open the art.ini file with a text editor? I can't find this file anywhere. I can get to it via the ra2.mix file using XCC Mixer but I can't alter it. HELP please.

You need to extract the ini file.
Right-click on art.ini in XCC Mixer, and goto extract, and select the game directory
