Designer Dave Delisle has detailed a conceptual product idea that would allow Wii U owners to play Nintendo 3DS titles through their television and Gamepad.
The Wii U peripheral, which he names the DSU, would let players plug a 3DS game into a box that connects to the Wii U console, placing the top screen of the 3DS title onto the user's television and the bottom screen onto their Gamepad.
"We've already seen two instances of Nintendo releasing a device that would allow a console to play handheld games: The Super Game Boy for the Super Nintendo, and the Game Boy Player for the GameCube," writes Delisle.
"And looking at the hardware DNA of the Wii U, it is very conceivable that a third device is possible. The Wii U's GamePad has a touchscreen, camera, microphone, and all the basic controls that would allow for the DS/3DS experience to be played on the console.
"The only feature that probably wouldn't make the leap to the Wii U is the 3D ability of the 3DS. There are glasses-free enabled 3DTVs on the market, but compatibility could be an issue. Seeing as 3D was always an optional feature for the handheld, I don't think this would be a deal-breaker for consumers."
Unfortunately, it's still just a dream.
