So today I bought a hacked Nintendo Wii U and I don't really know how it works. When I start the console I can launch games from an external HDD that came with the console. I also have an icon saying "Haxchi" on the main screen so I think it has Haxchi installed. When I launch the Haxchi app the console gives me an error -3, and also the Nintendo Wii U came without a SD card. Do I need a SD card with specific files to launch the Haxchi app? I'm new to this type of things. Thank you for your time :/
