I just tweaked the culture text file to give the new Altaics (Khazars, Bolghars, Avars) Pecheneg gfx. I also switched the d_pechenegs.tga to k_pechenegs, to reflect the new title. With those two changes, I think/hope that the mod should be compatible with TOG. I figure I might as well put it up here. I hope you don't mind, CrackdToothGrin
Anyway, just replace the folder of the mod package you're using with the appropriate one of these, and you should be good to go. However, all I did was copy the TOG cultures.txt and replace turkishgfx with pecheneggfx or cumangfx where appropriate, and switch 1 letter of the name of the image file for the Pecheneg tribal CoA. It's easy enough that anyone could do it on their own.
