What are you wanting to do to the mod? You can not change the login, but I am assuming you want the background and movie changed. (??)
yeahps exactly i dotn know what prgramme i can make it useable for bf2
easy to change background movies, just make a movie u want to use. Then replace one of the movie files in this folder programfiles/eagames/bf2/mods/bf2/movies so then change one of the files from say 'loginmovie.bk' to 'loginmovie.bkup' then copy in ure new movie and rename it 'loginmovie.bk' It may need to be a special file format (im not sure) but i think as long as you rename the extension aswell (.bk) then it should work. However dont hold me to that. hope that helps, Ali
Do a Google search for RAD Tools. It can convert your movie files to the .bik format. Works great for BF2.
