Hey, i Downloaded a f1 2011 Raikkonen red bull helmet, but i dont know how to put it into the game. The Readme file says: * Installation * Always make a backup of your files before any update, that's the secret to be never disapointed... 1 cars.wad Unpack your cars.wad, put the helmet textures in the cars folder. Recompile the cars.wad. What does Cars.wad mean? how do i use this?
