Unlimited items or gold:
Find a location that contains multiple items or gold, such as the first room in Oedo Castle. Collect the items, leave the room, then re-enter. The items will be available for recollection.

Boss mode:
Collect All forty-five Fortune Dolls to unlock a boss mode selection on the options screen.

Bonus picture:
Enable the "Boss mode" code, and complete the Boss sequence.

Control Impact:
Press the Analog-stick when Impact's introduction sequence ends to move his head.

Rumble Pak bonus:
Although not an official Rumble Pak game, the Boss levels will support that peripheral.

Hint: Slower falls:
Rapidly execute the Ice Attack or Coin toss while falling.

Hint: Avoid attacks:
Change characters just before an opponent attacks.

Hint: Avoid bullets:
Push C-Down to have bullets pass through your character.

Hint: Fighting Benkei:
Fight Benkei as Ebisumaru to throw the Achilles' Heel at him faster. During the battle, Benkei will threaten to blast you far away. This is a lie; he will knock you into the river next to the bridge where he is standing. There is a ladder available to return to your previous location.
