I have made a version of tk'S minimod that is compatible with the sprite pack. (copy and paste, 2 seconds work, hope it works )

here is the link

how to install:
just unzip the file into your RTW directory,
the sprite files are not included within this minimod , the sprite pack had to be downloaded installed before, this version of tk's minimod only has an adjustetd descr_model_battle_txt (short dmb) to use both the ebmodels as chariotdrivers / elephant riders and the new sprites.

@ tk

good luck with your new task
