Dark Trooper is a hard one.
I was going to make a skin pack, but I still have some trouble with a couple of skins. I can replace Dark Trooper in the .lvl file, but half of the actor is colored and the other parts default to black texture. I don't know why, so I'm just waiting to see if something to help me comes out. But all other skins in the imp.lvl I can get to work. Also, Super Battledroid. No matter which lines of text I edit in the cis.lvl file, Super Battlerdroid stays the same. It can only do this if it's getting its information from some other file or a line in the .lvl file I can't identify.
As far as the Hex stuff, Gametoast
has all the info you need to retexture. It's there, you have to read the stuff. No one is going to hold your and do it for you. Let me put it to you like this. See the photo below? I had no clue how to use a Hex Editor. I spend a little on Gametoast
and the result is down below. Good luck!
