The fixed exe from DEViANCE on GCW works good.
The fixed image from SKULL on GCW does NOT!
I also have another fixed exe that is from SKULL and that works good too.
I use the DVD image of the game loaded on a virtual drive (using Alcohol120%) with the use of "SafeDisc 4 Hider".
I prefere tihs method because I prefere to use ONLY game images (mini or big) and NO fixed exes or some cracked game system files.
Here you can find my personal Quake4 No-DVD PacK: http://rapidshare.de/files/6878199/Q..._PacK.rar.html
Jedimaster Player's method is also included.

Cheers.
