Some things
Cheats only work on the japanese version.
To get lv 10 weapons play on hard mode with a level 9 weapon.
Lu Bu: kill every unit (even ambush troops) then kill Dong Zhuo. You MUST kill every unit.
Jhang lioa (spelling): kill coa coa, sun jian, and lei bei on si shui gate and hu loa gate. They definatley work
I use these all the time.
