Nintendo revealed losses of 46.4 billion yen ($457 million) in its fiscal year report this week.
The Japanese company runs on a 12-month fiscal year ending in March.
Nintendo's tablet-driven Wii U console was a big disappointment, as the company moved just 2.72 million units globally for the entire fiscal year, according to AppleInsider.com. Just 18.86 million software units were also sold during the fiscal year.
The company said in its report that the Wii U faces a "challenging sales situation" looking forward.
Nintendo still expects the device to compete with the likes of the PlayStation 4 and Xbox One, by focusing on titles that allows gamers to utilize the Wii U gamepad.
The handheld Nintendo 3DS continues to be a strong performer however, in the face of smartphones, moving 12.24 million units during the fiscal year.
Over 67.89 million 3DS games were also sold over the last year, according to AppleInsider.com.
Portable devices running on Google's Android and Apple's iOS have been altering the portable gaming landscape forever, as more games are played on smartphones than ever before
Google's Play Store and Apple's App Store sales are four times greater than what Sony and Nintendo record from their gaming devices, as of August 2013, according to AppleInsider.com.
Apple has made a number of efforts to compete directly with Nintendo over gamers by selling Made for iPhone certified gaming controllers, which were released late last year.
Accessories like the controllers allow users to access Apple iOS platform with more "precise input in traditional-style games that may not benefit from a touchscreen," according to AppleInsider.com.
Rumors have circulated that Apple might jump into the home game console business with an update to its Apple TV.
Apple may also be planning to add a third-party App Store and gaming support to its set-top box lineup. This would turn the device into an iOS-based game console for HDTVs.
It would also allow Apple to compete with the Wii U, Sony's PS4, and Microsoft's Xbox One.
