Nintendo of America announced on Sept. 30 via NeoGAF that a new system update is available for the Wii U. The latest system update – Version 4.0.0 U – introduces a number of new features to the Wii U, new load screens for the eShop and Miiverse, along with several other stability and fixes.
The biggest addition found in the new Wii U system update is that players can now output video and sound to the Wii U GamePad while in Wii Mode. Basically this means you can now play Wii games on the Wii U GamePad – though Wii software will only be displayed on the GamePad screen. You will still need to use a Wii-mote or Classic Controller to play these titles. If you ever wanted to play Resident Evil 4 or Xenoblade in bed, now is your chance.
Some minor cosmetic changes have been made. You will now find the Friend List icon on the Wii U menu for quicker access to your Friend List. Meanwhile, the eShop and Miiverse have received a minor update in design as both now feature a more stylish loading screen. The eShop has a slot game where you can try to match three slides to form a game icon. Miiverse, on the other hand, has people circling the globe.
You can find the complete breakdown of the Wii U system update below:
A feature to output video and sound to the Wii U GamePad when using Wii Mode (Wii software displayed on the Wii U GamePad cannot be controlled by the GamePad.
