Hint: Winning in adult mode:
To defeat everyone in adult mode, choose Red Falcon. When you start a battle, keep doing the Left, Right, C-Down move. When your opponent is knocked down, go as far as you can to the corner of the arena, do a Searing Spear (Left, Right, B), and repeat the process. This is very useful against Ryumaou.

Hint: Defeating Metal Robo Na Hanna:
Use the Mr. Virus item to damage Metal Robo Na Hanna. Also use projectiles during the battle.

When playing as Ryuhi, make sure you have Dragon Scroll 2. When you fight him, use only his red blast attack and the attack learned with Dragon Scroll 2. Get as far away as possible and use the red blasts repeatedly. When he gets close, use the main blast attack or jump over him and repeat the process.

Hint: Defeating Metal Hayato and Metal Willer:
When fighting Metal Hayato or Metal Willer, just jump and kick them. It may take longer, but it is more effective than other methods.

Hint: Duplicate items:
Note: two controller paks with game notes on each are required for this trick. Start the game normally and go to the Treasure Box menu. Trade the item to be duplicated to the other pak, if it is not already there. 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 appears (either during the trading or after exiting the Treasure Box menu), press B. The game will ask whether you want to use a controller pak or not. Answer "No". Save it just in case by going into tournament mode, then cancel by pressing B. Reset the game. Put the controller pak back in. If done correctly, you should have a copy of the traded item in both game notes. This very useful for the legendary items and the Ring of Genie.
