adding a new emulated attachment for Taiko drum controller ("tatacon")

[kostmo]

I see in the "Core/HW/WiimoteEmu/Attachment" directory there are subclasses for Nunchuck, Turntable, etc.

What would it take to to implement a Taiko Drum Master controller (also known as "tatacon")? I possess a physical version of this peripheral that is recognized by the game as being an "official" tatacon. How do I snoop the ID, etc. from the real hardware? What fields are mandatory when implementing an Attachment subclass?

Here's a link to one other person that has wondered about tatacon support:

The tatacon is a funny shaped Wiimote. When I looked into it, the game uses the same data as the wiimote buttons.
