|0x100|-|-|Controller data|

* All multi-byte integers are little-endian.
* The encoding for all strings is UTF-8.
* Strings are padded with NULs if not filling the full field.
* Lengths are in bytes.

!!GameCube controller data:

The controller data is 8 bytes per frame.


||Byte #||Bit #||Meaning||Version added||
|0|0|Start pressed if 1||
|0|1|A pressed if 1||
|0|2|B pressed if 1||
|0|3|X pressed if 1||
|0|4|Y pressed if 1||
|0|5|Z pressed if 1||
|0|6|Up (Dpad) pressed if 1||
|0|7|Down (Dpad) pressed if 1||
|1|0|Left (Dpad) pressed if 1||
|1|1|Right (Dpad) pressed if 1||
|1|2|L pressed if 1||
|1|3|R pressed if 1||
|1|4|Change disc if 1 (on console, not controller)|3.0-785|
|1|5|Reset button pressed if 1 (on console, not controller)|4.0-4045|
|1|6|Controller connected if 1|5.0-5911|
|1|7|Reset analog inputs to origin if 1|5.0-10479|
|2|0-7|L pressure (0-255, none to max.)||
|3|0-7|R pressure (0-255, none to max.)||
|4|0-7|Analog stick X axis (1-255, left to right)||
|5|0-7|Analog stick Y axis (1-255, down to up)||
|6|0-7|C stick X axis (1-255, left to right)||
|7|0-7|C stick Y axis (1-255, down to up)||

* Bytes are numbered left to right. 
* Bits in byte are numbered right to left (as usual).
* Multi-bit fields have the most significant bit first (as usual).
* Also applies to Wii when using GameCube controllers.

!!Wiimote controller data

Wiimote controller data seems to consists of packets one after each other, each with the following format:

||Offset||Type||Length||Description||
|0|Integer|1|Length of payload (n)|
|1|Opaque|n|Payload (raw wiimote data)|

Some documentation about the raw wiimote data can be found from [http://wiibrew.org/wiki/Wiimote|Wiimote page at Wiibrew.org]. Note that the leading 0xA1 bytes are present.
