i look on diffrent web site and they say all the same cheat codes. some say, highlight fremode, other say highlight options and some just say the codes.

to the best of my knowledge, i believe these ones to be fake:
all wu generals.
all shu generals
all wei generals

this one should work though, if it helps making the game for fun for you:

Note: By competing one character in each force you will also unlock Yellow Turbans' Force as a selection in Musou mode.
