Romance of the Three Kingdoms IV: Wall of Fire cheats and cheat codes for Nintendo Wii

Beating Dong Zhuo:
Choose the Dong Zhuo Triumphs in Luo Yang (first scenario), then choose 
Cao Cao as your leader. Move some generals and troops to Xu Chang still 
on your very first turn. A few months later, Cao Cao will call a meeting, 
asking all the other leaders to form an alliance against Dong Zhuo. 
When Yuan Shao joins, he will become leader. Otherwise Cao Cao will 
become leader. You can beat Dong Zhuo a bit easier with this coalition, 
depending on who joins you (such as Yuan Shao or Ma Teng).
