The splash_screens.zip file you have requested: Miscellaneous / Alternate Splash Screens - 2.37mb is not available. Perhaps try browsing all files for the game Battle for Middle-earth II and upload any files you want to share or are missing. This is the only information we could locate:
These are nine wallpapers that I have resized to the correct splash screen size AND converted to JPEG format, so they are usable. They only work if you follow the directions on the readme, but there are only three super easy steps to follow, so no trouble.
