Complete the following tasks to get the hidden characters

Successfully complete the Ryumaou Tournament as Yuka at Rank S with 60 second, two round and normal difficulty settings. Note: You must already have nine medals.

Metal Robo Na Hanna has a very powerful magic. The magic he has prevents him from taking damage, and to make it worse damage normally done to him is done to you!
The only way to defeat him is to use the item "Mr. Virus" which steals his invincibility. The item "strategy book vol. 8" says it steals all powers, but it doesn't. When you get "Mr. Virus" and are fighting Metal Robo Na Hanna use a projectile attack or a projectile secret buster.

First you must have two controller paks to do this trick and a game note on each.
Start the game normally and go to the Treasure Box menu. Trade to the other pak the item you want to duplicate if it's not there already. Go to the Treasure Exchange option (if not there already). Take the controller pak that has the desired items out of the controller. Continue to trade. If a ''please insert the controller pak back into the controller'' message pops up (either during the trading or after exiting the Treasure Box menu), PRESS B! It will then ask whether you want to use a controller pak or not. say no. Save it just in case by going into the Tournament mode, then cancel out by pressing B. Reset the game. Put the controller pak back in. Voila! You should have a copy of the traded item in both game notes! It's very handy for the legendary items and the Ring of Genie....

Highlight the "Easy" difficulty option, then repeatedly tap Left until "Very Easy" is displayed.

For an easier game, go to the OPTIONS screen and set the difficulty to EASY, then press LEFT 20 times to enable the VERY EASY level.

This code is similar to the ???'s Z code. Press down twenty times at the title screen. Then go into the SD HIRYU mode and win a tournament. You will get a rare item when you do this.{I won a Mysterious Treasure and a Crown of Dragon King}.

At the title screen, while the ''Press Start'' icon is flashing and before the game cuts to the demo, press up on the control pad 20 times. Start the game and win a game in SD Circuit mode. You will get the ''???'s Z'' medicine as a prize every time. AFAIK, this is the only way to get this item.
