yeah but i dont like network stuff it just adds extra steps that arent needed, heck i even removed internet conection from my wiiu since i dont play any wiiu game online and cbhc is just gold.It's basically the same thing as Haxchi/CBHC, but you have to launch the browser in order to launch it.
Internet access is the most convenient way, but you can also self-host on a networked Windows computer if you don't have internet access. You can also self-host on an Android phone, and it doesn't even have to be on the house network.
since the OP is from europe he maybe has free brain training even if he didnt buy it, when i was about to install haxchi i went to e shop to buy brain training and it said 7 euro but afew steps further it said it was free, everyone in europe got it for free if they had a nnid made before a certain date, the op just has to check if he has it for free without knowing like i did.
