I found that in an older topic.
Richard Nixons Head said that under that direction the interface menues are... but I can't find them in my stardat.mpq.
Where to find it?

Try looking in install.exe if you can't find it in the other ones.

I remember I had that install.exe ages ago, but I don't have it anylonger.
I'm not using a CD btw.

Then it should be in the file you copied from the CD to use the no-CD feature.

I use deamon tools and a crack out of the internet.
In the crack-file is not the tcon.pcx etc, either.
Can you please attach the one for the zerg?

If you don't have a legit copy of SC, I'm not helping you.
