This is probably very stupid but I can't blame myself. The modders mention a simple format called .xtbl, but I don't see any on my game folder. I thought I needed to extract so I used Minimaul's one and all I got is nothing. I did got a .xtbl file, but it's not the one I am looking for. I need the "weapon_upgrades.xtbl" or so. And if anybody has a better way of manually extracting then please tell it (unless there's no need for it to get that .xtbl). So can somebody help me with it?
