Accidentally-Correct Writing: Thanks to the limited NES palette, Scrooge's frock coat is red, like in the comics, rather than blue as in the cartoon. Remastered, as a throwback to both media, uses the cartoon color scheme.
Executive Meddling: A preview of the NES version had crosses on coffins in the Transylvania stage (as shown in the "NES Official Strategy Guide"). However, Nintendo of America had to bowdlerise the stage so that the coffins now say "R.I.P." on them in the final version of the game.
Issues with DuckTales: Remastered's licenses, expiring in 2019, caused the game's removal from digital stores on August 8-9 that year. Fortunately though, you can still obtain it physically at least.
Rescued: However, on March 3, 2020, the license for the game was renewed and it was brought back to digital distribution services on supported platforms.
Limited Special Collector's Ultimate Edition: The PS3 version of the game had a retail version of the game containing a voucher to download the game and a collector's pin. The Wii U's retail version will also have the collector's pin along with the game disc, but it is exclusive only to Target retailers.
No Export for You: The Remastered version was not released in Japan. Justified, as the original NES game was made for Western audiences in mind. Averted when the iOS/Android ports came.
The Other Darrin: New actors were hired to play the characters listed below in the remastered version because the original actorsnote Joan Gerber, Hal Smith (Gyro and Flintheart) and Hamilton Camp respectively had passed away by the time the game was developed:
Role Reprise: The remastered version features the then-surviving voices from the TV series, including the late TV Legend Alan Young as Scrooge McDuck, who was 94 at the time of the game's announcement, and the late voice over legend June Foray as Magica DeSpell, who herself was 95 years old at the time. This is definitely justified by Capcom's corporate officer/senior vice-president Christian Svensson, who said when taking a question from a fan: "We have ALL the original voice actors from the show. Scrooge's voice actor, Alan Young, is now 94 years old but he still came into the studio and did his thing like a pro. The voice work really adds a lot to the package."
The Remastered version was originally going to include Scrooge's alter ego, the Masked Mallard (from the episode of the same name), as an unlockable costume.
Menu screens featuring the WayForward character Shantae (from the game of the same name) were found dummied out as well.
Japanese copies of the NES game kept the infamous "dream and friends" ending from the prototype.
