Hey guys i downloaded a full and latest version of generals zh and when i open it i see the animated video with the music...but when i copied the main folder and started editing it for a mod all i see is a picture with no music instead of that animation... how to fix that please ...also how to make a new animation and make it play in main menu

Your game probably started in the quick start mode and making a "animation" (shellmap) in the background isn't actually an easy process, it's made using scripts and repeating scripts, you can see shellmap if you extract mapszh.big using finalbig editor.
