While Nintendo is busy working on it’s newest game console, one programmer is busy working on an emulator for Nintendo’s most recent console the Wii U. This project would make for the first that we have seen for the Wii U and the first of the 8th generation of consoles.
The project at this point is just in the beginning stages so it will be some time before we see any form of in game screenshots. As right now the project is just working on emulating the most basic of system architecture (which isn’t exactly “basic”).
If you are interested in this project and have questions, there is a great thread on /r/emulation which several devs from other emulation projects have answered several questions on the basics of emulation. There are also comments made by the developer of this project himself as well.
