The Wii U has been out for just over four years and whilst it does have a few awesome games and some cool hardware, it hasn’t really done well for itself, this perhaps could be blamed totally on Nintendo, for example the Wii U still remains more expensive than the younger more advanced PS4, combine that with the companies lack of third party titles and we have a disaster.
Anyhow if you own a Wii U and have been upset with its lack of games, you can fix that by hacking it to enable Homebrew and play all your favourite Emulators, something that used to be quite difficult is now extremely easy, below is a super easy guide taken from GBATemp:
-A WiiU connected to internet
-An SD Card (any sd card is fine)
1. Plug an SD into your WiiU
2. Visit http://wiiubru.com/go on your Wii U and press continue; this will load the Homebrew Appstore (loading times may vary in base of you internet connection; if it takes more than 2 minutes your WiiU is probably crashed, so reboot it and try again)
3. Download the Homebrew Launcher and the apps you wish to have (remember to thank @vgmoose for Homebrew Appstore)
4. Done! You can now launch the Homebrew Launcher (with the SD Card plugged in) by visiting http://wiiubru.com/x (or http://loadiine.ovh choosing Homebrew Launcher 1.3 package) on your WiiU’s browser every time you want to use homebrews
