Yu-Gi-Oh! The Dawn of Destiny

When you fight Yami Yugi, and flip Cyber Jar on your turn, Yami doesn't get the effect at all.

If you play an equip card that will hieghten a certain type of monster's ATK or DEF, and that type of monster is not there, there will be a glitch where you can't equip the card to any monster and everytime you try and cancel, it will bring you back to the "select a monster to equip" menu. You will have to restart your game to disable the glitch.

When you play a field card, the field card's screen replaces the default screen. If the field card gets destroyed, the screen gets disabled and the default screen gets put again. When yoo play a field card, and the screen appears, and then try to put another field card to replace the field card you have, and that field card gets eliminated by a spell or trap, that field card gets destroyed along with the field card that was put in play. The thing is, the first field card's screen will still be there instead of the default screen.
