How to install:
First, extract all the files to a folder of your choosing then
download xdelta ui (you can find it on romhacking.net) and apply the 2 patches.
Skelmeshespatch must be applied to meshes.dat (found in DNF's SkinMeshes folder)
Staticmeshespatch must be applied to staticmeshes.dat (found in DNF's StaticMeshes folder)

Then, download texmod and select in package mode the 2009 Duke Texture package tpf file 
(otherwise Duke will look like shit, even worse than being Douche NotCum)
then click on the select process to run, pick DNF's exe (which you can find on the game's System folder) and run
it with this package added in.

You are done!
There are issues however, noted in the duke4 post where I posted this file.
Mod made by futuretime23, big thanks to TeaMonster and Judgement_fist for the help in getting the Duke back in
action!
