Hello, you'd need these animations in order to play most of the chinese mods found at the Wanmod-site - including for this mod Republic of China 1924. The folder needs to be extracted using the latest or most recent version of WinRAR (WinZip could also do) and then you'd just have to place it inside of the SEGA\Medieval II Total War\data-folder. When this is done you should be able to enter most Chinese mods - instead of being returned to the desktop!
