Hello! I have been trying to make some very simple little mods for KotOR 1. Just making a few new items with different statistics to use based of of what is already in the game. 
  
I am running into a problem though, I have been using KotOR Tool and making the changes I want to items. 
When I save the resulting file to my override file though they do not work. 
  
Firstly the files do not seem to have a type my computer can even detect. 
And no matter what I do I cannot get the items in the game. 
If I try using the save editor they do not show up on the list of items. 
If I try using giveitem within the game I get something in my inventory that has a grenade icon but no text. 
  
I would really really like to not have to overwrite existing items to add the ones I made in so if anybody might know how to fix this I would be so truly thankful!
