Romance of the Three Kingdoms 8
During play, pause and select "Quit." Set the CPU to control your officer, then quickly hold L1 + L2 + R1 + R2 + Select. A window will appear that allows you to control one of eight other officers.
Select "New Officer" at the main menu and choose "Create New Officer." Use the case-sensitive names below in the new officer creation, and ignore the first name and last name boxes - put first name in the last name box and last name in the first name box.
