Well, in case of weapons anim folder contains two archives. One to define weapons sprite when its placed on the ground. Its usually called just goldsword.zip for example. And one which will be used when game plays swapping and striking animation swap_goldsword.zip. All archives contain .tex file which is a picture - weapons's sprite (you know that if you have repainted boomerang) and a build.bin file in which game defines what graphic files will be used. For example if you wish to rename goldsword.zip file into batarang.zip you'll need to change this filename in all assosiated script files and what is the most difficult - in build.bin file. There should be a thread about editing .bin files. I myself used hex editor to edit .bin files, but there should be an utility that does it without hex editing. And there is a thread about working with anims, it explained there much better than I can.
