The wii homebrew library (libogc) now supports the Wii U pro controller. I have compiled and adapted the FBZX Wii code to the new library. Since I don't have a Wii U pro controller, could please someone test if the new code supports it? Here the link to the program: https://drive.google.com/open?id=0BzmiDeFEjxKaRktfYnk0ZFp5RnM You have to copy the files in the SD card. Here the link for the installation and usage of the emulator. http://wiibrew.org/wiki/FBZX_Wii I included a special configuration file to test the Wii U pro controller button. Pressing the button and moving the Joystick and DPAD the emulator should write numbers and letters in ZX Spectrum prompt. Thanks.
