Password mode:
On every Duel Monsters card is an eight-digit password on the lower left corner directly below the card's picture. Enter this code at the "Password" option on the main screen, and the card will be recorded into your card collection. Note: You can only enter the password once.

Easy Starchips:
When you start the game you will fight someone. After you defeat them, save your game. Go to free battle and battle all you want to receive 5 Starchips. Keep doing this until you have as many Starchips as needed. 

Summon two Dragons:
To summon two Dragons you need to have the Flute Of Summoning Dragon (43973174), The Lord of D. (17985575) and two Dragons in your hand. Put the Flute Of Summoning Dragon on the field when Lord of D. is face up. When you do this you can play two Dragons as a special summoning.

Gate Guardian Ritual:
Have #374 Gate Guardian, #667 Gate Guardian Ritual, #371 Sanga Of The Thunder, #372 Kazejin, and #373 Suijin in your deck. Put them in your field, then put the ritual card.

War Lion Ritual:
Have #673 War Lion Ritual (card), #483 Garvas, #403 Leogun, and #201 Frenzied Panda.

Zera Ritual:
Have #671 Zera Ritual (card), #377 Ryu-kishin Powered, #298 Wicked Dragon with the Ersatz Head, #085 King Of Yamimakai. 

Deck change:
The game displays a password after it has been completed (for example, 92445276, 25774450, 92886423, etc.). This password is to change your deck. After you enter the password, check your cards. 

How to make a Twin-Headed Thunder Dragon 
It's really easy to make a Twin-Headed Thunder Dragon once you mastered it. All you need to do is:
Once you got a dragon type, a machine type, and a thunder type in your hand, combine them in this order: Dragon + Machine + Thunder = Twin-Headed Thunder Dragon. But, if your dragon has the attack power more than 1600, you just need to combine a thunder type with it.

It's REAL EASY

thanks bye (please no fake cheats!!) 


3D Battle Arena:
To get to the 3D Battle Arena, press X on one of your monsters, then press Square instead of using X to attack again.

Blue Eyes Ultimate Dragon at full power:
Use three Dragon Treasures, one Mountain, three Megamorps and one Bright Castle and its Attack power will be 9999

The following things can be used to power up the Summoned Skull card.

Sword of Dark Destruction
Malevolent Nuzzler
Black Pendant
Bright Castle
BeastFangs
Horn of the Unicorn

Duplicating cards:
Three memory cards are required for this trick. One can be a PlayStation2 memory card if needed. Refer to the memory cards as A, B, and C. Insert memory cards A and C. Memory card A should have the cards you want to duplicate. Copy the Yu-Gi-Oh Forbidden Memories saved game file to memory card C. Start a game and insert memory card B. This memory card be should also have a game in it with a different I.D. Trade the cards that you want from memory card A to memory card B, then reset the game. Return to the PlayStation memory manager and copy the saved game file from memory card C and put it back in memory card A. Memory card A should now have your old file with all the cards that you traded to memory card B. Next, go to trade and put all the cards you traded to memory card B into memory card A. If done correctly, you should have doubled the cards that you wanted.

The following trick gives you extra cards for free without dueling or using starchips. You need two memory cards. Refer to the memory cards as A and B. Memory card A must have a save file on it. Insert memory card B into memory card slot one and start a new game. Save that game to memory card B, then reset the game. Go to the build deck menu and take all the cards you want out of your deck and exit the menu. Save your game and reset the PlayStation. Insert memory card A into memory card slot two. Go into the trade menu and select all the cards (or as many as you can) from memory card B and press Square on controllers one and two. A menu will appear. Press X to select "Trade", then "Yes". You will now have all the cards from memory card B (that you traded) in memory card A.

Never use up Starchips:
This trick requires three memory cards. Memory cards A and B should have your main game save. Memory card C should just be any game with a different name than your normal game. Put memory card B in slot one and memory card C in slot two. Load your game, buy your desired cards, then save and back out to the main screen. Then, go to "Trade" and trade all the cards to memory card B. Insert memory card A into slot one and trade the cards back from C to A. You have now purchased cards and gotten them for free.

Buy any card desired:
This trick requires three memory cards and 999,999 Star Chips. Get 999,999 Star Chips on memory card A. Then, start a new game (or have an existing game) on memory card C with a different name than used on memory card A, and save at a Card Shop. Copy the game on memory card A on to memory card B. Use the 999,999 Star Chips on memory card B to buy a good monster and save. Trade that good monster to memory card C, then to memory card A, and you will have a good card and still 999,999 Star Chips to copy to memory card B again to repeat the process. 

Getting good cards:
Once you have defeated the Meadow Mage in campaign mode, duel him in free duel mode. He gives you some very good cards after some time, such as Meteor B. Dragon (3500/2000), Dark Magicians, Curse or Dragon, Giaia The Fierce Knight, Crimson Sunbird, and others. 

Fighting Simon Muran:
At the beginning of the game, Simon talks to you. You will have options to listen or run away. This is what he will do on each condition:

Run Away: When you return, you will go straight to your room. 
Listen, Run Away: When you return, you will have a chance to duel with Simon Muran.
Listen, Listen, Run Away: When you return, you will go straight to your room.
Listen, Listen, Listen: You will go straight to your room. 

Easy Starchips:
When you start the game you will fight someone. After you defeat them, save your game. Go to free battle and battle all you want to receive 5 Starchips. Keep doing this until you have as many Starchips as needed. 

Summon two Dragons:
To summon two Dragons you need to have the Flute Of Summoning Dragon (43973174), The Lord of D. (17985575) and two Dragons in your hand. Put the Flute Of Summoning Dragon on the field when Lord of D. is face up. When you do this you can play two Dragons as a special summoning.

Passing the labyrinth:
After you win, go right, right, left, right. Then, you save Tea and fight two opponents before Keishin. Then Seto appears and the end is Darknite.

Kuriboh the card carrier:
To find Kuriboh packing cards, lose a battle in campaign mode. When you get to the "Game Over" screen wait until a Kuriboh with cards on its back will hop across the screen. Once it gets across, it will return again. It will repeat this until you exit the "Game Over" screen. 

Guardian Star color:
Whenever you see the word "Guardian Star", pay attention to its color. 

Yellow: Your attack and defense goes up.
Red: Opponent's attack and defense goes up.
Gray: Neither goes up. 


War Lion Ritual:
Have #673 War Lion Ritual (card), #483 Garvas, #403 Leogun, and #201 Frenzied Panda.

Zera Ritual:
Have #671 Zera Ritual (card), #377 Ryu-kishin Powered, #298 Wicked Dragon with the Ersatz Head, #085 King Of Yamimakai. 

Deck change:
The game displays a password after it has been completed (for example, 92445276, 25774450, 92886423, etc.). This password is to change your deck. After you enter the password, check your cards.
