The SNES controller is very similar to the NES' standard controller, with a collection of digital inputs that are latched and read in series. With a suitable adapter, reading the SNES controller is like reading an NES controller with 4 extra buttons.
The 16 bit report:
| bit | input |
|---|---|
| 0 | B |
| 1 | Y |
| 2 | Select |
| 3 | Start |
| 4 | Up |
| 5 | Down |
| 6 | Left |
| 7 | Right |
| 8 | A |
| 9 | X |
| 10 | L |
| 11 | R |
| 12 | 0 |
| 13 | 0 |
| 14 | 0 |
| 15 | 0 |
Note that the first 8 values map directly to the original NES controller's 8 inputs (SNES B = NES A, and SNES Y = NES B).
The last 4 bits will always read 0 from a standard SNES controller. Other values here may indicate other devices[1].
After the 16 bit report, subsequent bits will read as 1.
