Its work fine without your file, i test with another WiiClassic.h, attached it.
This another WiiClassic show in the "monitor Serial" all buttons ok, but i need change all the code for use this WiiClassic with Joystick.h and make windows recognize arduino like a joystick.
Your file is perfect, but with me have this little bug.
I will try something more and post.
