Jackie Chan Adventures: Legend Of The Dark Hand

Cheat mode:
Hold R and press B, A, Left, Down, Up, Right at the ''Press Start'' screen to unlock all levels and scrolls. Alternately, hold R and press B, A, Up, Down, Left, Right.

Hint: Defeating Hak Foo:
Know your distance when doing a Roll. While Hak Foo is walking towards you, Roll towards him quickly. You must land about where Hak Foo is standing. Roll forward again so he does not hit you. Next, Backflip the same way as a Roll twice. You should hit him sometimes if you continue this pattern.

Go to the far upper right corner where the car is located and jump on to the hood. Stay there until Hak Foo appears. At this height, he will not attack but the people that help him can. Do front kicks at Hak's head and beat him. His helpers will run back.

Hint: Defeating Hak Foo 2:
This is an easy battle, and uses the same tactics as the first Hak Foo. If you get cornered along the southeastern wall facing right, use the Shen Scroll Attack (B + R + Up) to leap behind Hak Foo and quickly attack before he guards. Then, roll away.

Go to him and do three MAO scroll attack repeatedly. The men will run away or block.

Hint: Defeating the Moon Demon:
Stay as far right in the beginning and face left while blocking. Time a Roll left once the Moon Demon throws an Eclipse. If you do it too late, the Eclipse will cause major damage. Note: Block only when the Shadowkahn are still there. Once the cloud covers the moon, quickly Roll towards it and attack as fast as you can using the Mao Scroll Attack (preferred) or Xu Scroll Attack.

Hint: Defeating Shou Foong, the Wind Demon:
Stand directly in front of him. When you stand still, in two to three seconds Shou Foong will inhale. Time a Roll immediately when it is about to inhale. You should end up about behind Shou Foong. Once it finishes blowing, attack its back with a Mao Scroll Attack (Up + A), which you should have gotten. Continue this pattern.

Hint: Defeating Valmont:
Just like Hak Foo, time your Roll to end up at Valmont. Do it twice in a row, then attempt a Flying Kick attack (R + B) at Valmont. Then Roll away and repeat.
