| 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 Wiimote page at Wiibrew.org. Note that the leading 0xA1 bytes are present.
