How to customize the game icon interface?

[Graion Dilach]

oh, well... I expected you to read that damned documentation.

[Side]►Sidebar.MixFileIndex= (integer)
The MIX file number to use for the sidebar (e.g. 1 for the Allied sidec01.mix, 2 for the Soviet sidec02.mix).
[Side]►Sidebar.YuriFileNames= (boolean)
Whether or not to use the Yuri sidebar file names (sidec02md.mix and the Yuri-specific files within that MIX).

Your sidec04 needs Sidebar.MixFileIndex=4 and Sidebar.YuriFileNames= (default) and your IQ level also needs a buff.
