Thank you for trying out the emulator, I appreciate the feedback. I have been focused on trying to find ways to speed up the core emulation, so I have not documented things outside of code. With a wii remote you can point and press A and that acts as the stylus. With the gamecube controller, you can use the c-stick as the stylus and click z. I don't own a Wii U pro controller, so I hadn't thought to add it yet. For Bios files, like the standard NooDS, it needs them or most games won't boot. As for the home menu and browsing combos, I initially had them in, but the code was not having the intended result, so I removed those from the v1.1 release for the time being.
