Debug Menus#
Using the Game Genie codes 084-3BB-F72 094-25B-F76 with a Japanese or US copy, or by changing 0x10425 to 09 and 0x1043B to 08 in the ROM, the player can access two hidden debug menus. To access these two, the player must move the cursor below "Password".
Sound Test#
Choose to listen to either the songs (きょく) or sound effects (おと). Music goes up to 33, while sound goes up to 20. The only controls are A to play a song, and B to exit back to the menu. The text is mojibake in the US version, but the menu remains functional.
Character Animation Viewer#
View all of the opponents' cutscene animations, which can be viewed by pressing A. The index only goes up to 23. Anything higher and the game sends the player back to the menu. However, no matter who is selected, Weevil's intro dialogue is loaded.

Debug New Game#
Using the Game Genie codes 008-31A-5D4 018-0CA-E6A C82-79A-195 with a Japanese or US copy, or by changing 0x5279 to C8, 0x1180C to 01 and 0x11831 to 00 in the ROM, debug features are available when starting a new game :
- Deck Capacity is set at 9999.
- Duelist Level is set at 255.
- 200 copies of every card.
- 200 copies of construction cards from 0-0 to 9-9 and 70-70 to 79-79.
- 9 wins against every opponent except DarkNite.
- 4 wins against DarkNite.
- Grandpa gives a card after each duel.
Debug Card#
The construction card 3 69 was used for debugging purposes. Several parts of the battle program are skipped for this specific card:
- Equip spells are ignored.
- Field spells are ignored.
- Spellbinding Circle and Shadow Spell have no effect.
Unused AI#
These behaviors are never seen in-game as the CPU decks have no cards that trigger these:
- The CPU can play Trap cards, but it doesn't check if the opponent is under the effect of Swords of Revealing Light.
- The CPU can play every Equip Spell card in the game.
- The CPU can check if there are monsters of a certain Type on the field before playing Type-specific Spells, such as Eradicating Aerosol or Stain Storm.
- The CPU can play the Multiply + Kuriboh combination.
- The CPU can play Cursebreaker.
- The CPU can play Metalmorph.
- The CPU can play Stop Defense, but it will only activate it after attacking with its monsters.
Unused Card Color#
The color ID 02 is not used by any card in the game. It was most likely supposed to be used for Fusion Monsters, but they decided to make all Fusion Monster cards the Normal Monster card color instead, most likely because of the different Fusion game mechanics they programmed into the game, and also probably because a couple of them have new effects and use the Effect Card color.
Unused Functions#
- At 0x1683C, the function that decreases Deck Capacity is completely unused. (It was used in Yu-Gi-Oh! Duel Monsters II: Dark Duel Stories after a Card Password was entered).
- At 0x2555C, a function handling an 8th special password is completely unused (See the text said by Simon Muran in the Unused Text section).

To do: |
At offset 0xA045 is a string that should be displayed after beating Marik 5 times, but is never used:
It can't be!
Not 5 times!
As long as there
be darkness...
I should remain
invincible!At offset 0xA31A is an untranslated string that should be displayed after beating Nitemare 5 times, but is never used:
Gwaaah...
I can't believe I've lost 5 times already!!
Leave now, before I change my mind!At offset 0xA9C2 is a string said by Simon Muran that is never displayed in-game. It was supposed to be triggered by entering the 8th special password located at 0x25245, which has been replaced by 0xFFFFFFFF, it would then display a card (it fails and temporarily displays a white screen), then display the ending "To Be Continued" screen. It was likely an alternate ending credit which might have used the unused Ending music. You can restore a part of what is left of the sequence by replacing the 0xFFFFFFFF at 0x25245 by an enterable password in the ROM:
Very good! You've
found the secret.
The secret of the
legendary card...
It's hidden here.
Your password...
It will reveal it
to your eyes!At offset 0xAA4E (0x9E88 in the Japanese version) is an untranslated test string said by Yugi Muto:
This is a testAt offset 0x15360 is a string that is never displayed in-game, even when an equip card has no effect on a monster:
Used [Card Name]
Power-up was
unsuccessful.At offset 0x15455 is a string for an effect that is never used in-game, as in the final game Megamorph only increases the level of a monster by 1 instead of 2 as in the prior game:
Used Megamorph
Level increases
by 2!Build Date#
« 99 12 25 KONAMI »
This string, present at 0x11891 is written to the save file upon creation. When loading a save file, the game looks for the string to determine if save data exists.
