The Standard Controller has 12 buttons:

  • A
  • B
  • X
  • Y
  • Start
  • Select
  • L
  • R
  • Up
  • Down
  • Left
  • Right

Normally, up to two controllers can be connected to the control deck, but the MultiPlayer 5 can expand that up to 5.

Its signature is 0000. [2]

Internally, the standard controller contains a 16-bit shift register.

Edge Detection is a technique for processing controller data. [3] It can mitigate chattering.
