Hints and Cheats...Avoid Attacks
Here's an easy way to avoid an attack. Just change your character before your enemy attacks you and it will go right through you.
Blade-Shield Tip
When Yae uses her blade-shield, she normally can't move. However, if you have the armor or shield and receive damage from an enemy when using the blade-shield, you can move.
Boss Mode
If you collect all 45 of the Fortune Dolls throughout the game, it will unlock a special boss mode under the options section.
Easy Money
If you find a room with a lot of gold (or pots with gold) such as the first room in Oedo Castle walk into the room and get the gold. Then leave and come back in and -- surprise! All of the gold is right back where it was! You can do this as many times as you want and stack up on cash.
Fall Without Pausing
When falling from great distances in Mystical Ninja you will hit the ground and pause getting up. To avoid this, press the WEAPON button before hitting the ground and you'll be free to move as soon as you land.
Faster Ladder Climbing
To climb a ladder faster, press A rapidly to jump up the ladder. But be careful! If you don't watch how high you are, you can jump right off the top of the ladder and fall.
Glitch Room
In the underwater submarine, swim up to the spinning blade in the first room. Swim past the exit in the ceiling. Now head straight up. Eventually you will pass through the ceiling and will not be able to get down. You can move around in a little cube of water, but can only see what is around you. Not a really useful code, but fun nevertheless.
Golden Hair
While using Goemon's touch-and-go skills, get killed by an enemy (if you have more than one life.) If you do this, you will come to life again with golden hair. However, if you want to change the character, you can't change the hair color.
Hidden Image
As you know if you collect all 45 Cat Dolls you get a consecutive fighting boss mode in the option screen, well if you complete it you will get a nice CG pic of the Mystical Ninja gang!
Move Impact's Head
At the end of the Impact's intro sequence, when the red and yellow stripes are spinning behind Impact, you can move Impact's head by pushing the analog stick in any direction.
Move While using Weapon
When you use your weapon you can't move,but if you start to move and while still moving you can press the attack button you can then move!
Ninjitsu 360° Blade Slash
Rapidly rotate the control stick in a 360° motion while rapidly taping the B button. This produces a Ninjitsu 360° Blade Slash that will kill all the enemies around you.
Play with Impact
After Impact (the big robot you hop in) is done with his song intro, it shows him holding up his staff and yellow stuff and flowers are circling him. At this point, you can move the control stick and bob his head around!
Rumble Pack
Even though the game wasn't made for the rumble pack it will work on the boss stages.
Tightrope Level
In the ghost level with the tightrope, fall off the indented cliff alittle left of the tightrope, and you will disapear. Hit the directional pad towards the cliff and you will reappear on top.
Transporter Trick
After you get Ebismaru's shrinking capability, you can go to the transporting place for a neat trick. Shrink, then talk to the lady to get a ride. You will run up to the transporter and jump, but not quite make it up inside. The transporter leaves without you.
