Hint: 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.
Hint: 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.
Hint: 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.

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.
