DuckTales is the NES game based on the classic (well, 1987–90 "classic") Disney cartoon. WOO-OO!

In 2013, the game got a remake that added some elements and reunited the remaining voice talent from the show.

Unused Graphics

NES Controller

Beep boop.

The graphics and 2×2 metatiles are all that remain of this NES controller, found amongst the ending cutscene data. The B and A buttons use a separate palette, though the actual color values have not been found.



It's...a bomb. Its original purpose is unknown, as it has no associated sprite data, though a similar object did appear in Chip 'n Dale Rescue Rangers (which could be picked up and thrown at enemies and dim-witted partners).

"Secret" Bad Ending

There is an ending that can only be seen by completing the game with $0, but it is incredibly difficult to get without cheating:

  1. Arrive at Dracula Duck's chamber with a total money amount divisible by exactly 3,000,000.
  2. Take damage.
  3. Press Select to restore your HP (this costs $3,000,000).
  4. Repeat steps 2 and 3 until your money is completely drained.
  5. Defeat Dracula Duck and recover the treasures.

If you did it right, you will see an ending announcing that Scrooge has lost his fortune. Considering how difficult it is to pull this off, this method of accessing it seems more of an unintended consequence of the cheat. It would seem that Capcom had originally planned some other way for Scrooge to lose all his money, or just added this as a sort of "catch-all" in case it happened.[1]

Unused Text

The following text is located at 0x13C26 in the ROM:


Perhaps the King of the Terra Fermies originally occupied Louie's spot at the entrance to the African Mines, and you had to bring him a gift (rather than a key) to pass?

Debug Leftovers

Holding Up on the second controller while falling into a non-lethal pit wraps Scrooge to the top of the screen. This is likely a debugging leftover that developers forgot to remove.

Regional Differences

The European version increases Scrooge's movement speed in an attempt to compensate for the lower framerate of PAL televisions. As a side effect of this change, Scrooge can just barely jump over the large gap in the second part of the Amazon without assistance from Launchpad.

The Japanese version uses the ending screen from the prototype, which is the only bit of English text (aside from the title screen and status bar) in the game.
