Press X on one of your monsters, then press Square instead of using X to attack again.

Don't try to get the password for monsters that appear in the tv series, they cost 999999 chips

e.g. Exodia, Baby Dragon, Blue eyes White dragon.

This trick only works with monsters that can be fused into new ones through magic cards. Lay the monster down the turn you have it and the fusion magic card in your hand. During the next turn, lay down the magic card face down and attack with the monster, without using the magic on it. Then, go to the magic card and use it on the monster. The monster, which was once grayed, is now usable again. For example, Jirai Gumo (2200/100) is played the second turn and the card Metalmorph is in your hand. The next turn, play Metalmorph face down on the field. Since your opponent does not have a stronger attack or defense of 2200, attack with Jirai Gumo. After the battle sequence, use the Metalmorph on Jirai Gumo and it becomes Launcher Spider (2200/2500) and is no longer grayed. You can either attack again or switch to defense position.

When you are battling your opponent will always play there strongest monster on there first turn or a trap or magic.

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.

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.

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.

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.

After you beat the Low Meadow Mage, Return to the Card Shop and save. After you save, return to the menu where you can have freeduels. Duel the Low Meadow Mage About 200 times and you may get:

2x Meator B. Dragons 3500ATK
2x Skull Knights 2650ATK
2x Dark magicians 2500ATK
2x Gaia the Fierce Knights 2300ATK

Also duel the other mages to get curse of dragon(2000ATK). The mountain mage should give you this. Then you can fuse Curse of Dragon and Gaia the fierce Knight to make Gaia the Dragon Champion(2600ATK)

Many of the early Yugioh games allow you to exit the deck-building screen whether you have a full deck or not (unless you are about to or are currently playing a duel). In Forbidden Memories, exiting the deck building screen will force the campaign mode or Free Duel mode to exit out automatically until you have a full deck ready and available. Sounds counterproductive, right? Well, here's the real kicker, here: You can save your game immediately afterwards. So in essence, you can pretty much save your game after you empty out your entire deck, exit out of your current load game, and then trade all the cards that were once in your deck to a second memory card. This is highly invaluable if you desire to build your deck with the very best cards available right from the start (like, say, nothing but Dragons and Thunder monsters as well as suitable equip cards and Raigeki's). This is not only a highly invaluable hidden technique that is helpful for speed running, but it can also help you defeat Heishin using nothing but the cards you can get in your Starter Deck. Maybe even collect a number of rare cards as well as a near-complete list of Equip cards, 3 Raigeki's, and a complete set of Field Spell cards.

On your first turn, put a strong card that the CPU will not be able to kill. It should now put down a card and place it in defense mode. On your second turn, put down a weak card in defense mode and leave the strong card in attack mode. The CPU should fuse its cards. If not, start the battle again.

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.

After you win, go Right, Right, Left, Right.

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.

Use the following trick to power up Twin-Headed Thunder Dragon to 5000+ ATK Points. First, you will need the cards that will create the Twin-Headed Thunder Dragon: Any Dragon + Rock + Thunder or Dragon Zombie + any Thunder. The other cards you will need are one Mountain (Magic), three Horn Of Lights (Magic), and three Dragon Treasure. To get three Horn Of Lights and three Dragon Treasure, try starting a new game on another memory card. Try to start with a deck with the Horn Of Light or Dragon Treasure (getting both of them at the same time is almost impossible); then trade onto the game you are permanently playing. Since you cannot get the magic card back on the temporary memory card, keep starting a new game on your temporary memory card and try to get a starter deck with the Horn Of Light (getting a Raigeki is also good). After all that is done, free duel anyone with the memory card with the permanent game. Have the Twin-Headed Thunder Dragon already on the field, and if it can be done, if all three Horn Of Lights or Dragon Treasures are in your hand, press Up on all of them and combine with the Dragon. If not, just wait and it will happen. With the three Horns, three Dragon Treasures and the Mountain combined with the Dragon, its ATK power should be about 6300.

Combine the Twin-Headed Thunder Dragon with three Dragon Treasure, three Horn Of Light, three Invigoration, two Megamorph, and one Umi. Its ATK power will be about 9800.

Use the following power-ups to power up Twin Headed Thunder Dragon to a 9300 ATK: one Mountain, three Horn Of Lights, three Beast Fangs, three Dragon Treasures, and three Dark Energy.

Mamoth Of Goldfine= Mamoth Graveyard+Strong Zombie
