You said yourself that the Balance Board simulates a Wiimote with an expansion device. Hence it's not an expansion device, as it's stand-alone.

I have tested Devolution with the Wii U Pro Controller and it's actually amazing. First I was confused when I realized the buttons were not mapped to match the names of the gc controller buttons (Y is B and B is A etc), but I got used to it very quickly. The only thing that I dislike is that if I exit to the HBC to select another game I can't use it anymore. It would be really cool to have drivers that enable the Wii U Pro Controller globally. I don't think Nintendo will ever update the Wii again so I think those drivers would be save. Please make this happen, tueidj! I don't think anyone else other than you can make this happen

If you want to access the motion plus data, it must be done via the expansion port regardless of whether the motion plus is built in or externally attached. So it's always an expansion device even when it's part of the wiimote.
The balance board is like a giant wiimote with no accelerometers or camera, one single button and four weight sensors connected to the expansion port. If a device uses the wiimote's expansion port for communication, surely it is an expansion device?

Both of them have the same terrible stick sensitivity - the L stick ranges from 0 to 63 and the R stick ranges from 0 to 31 (and they are never calibrated properly). In contrast, the gamecube sticks and PS1/2/3 controllers all range from 0 to 255 and the wiiu pro sticks range from 0 to 4095.

Q: Does the current revision (of GCN to CC adapter) support the full range of the Gamecube sticks (0-255) or only the limited one of the CC (0-63 and 0-31)?
A: Only the limited one. Doing better would require implementing a special mode
in my adapter and having the Devolution developer support it. This special
mode would also be useful to some homebrew apps.. For now I'll add this
on my list for future features.

So would you be interested in adding such support in Devolution tueidj?

I don't think he has to implement a special mode. The classic controller uses 6 bytes for reporting data which the wiimote reads from offset 8 of the extension memory, but depending on the reporting mode the wiimote can return up to 8, 19, 16, 9, or 21 bytes. So all he has to do is make his adapter put the real stick/trigger values after the normal 6 bytes of CC data and I can read them using the 19 byte reporting mode (which I always use anyway because it's needed for the WiiU Pro). Also put a couple of signature bytes on the end to distinguish it from a real classic controller.
