Standard Controller

The Standard Controller has 12 buttons:

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

L and R are shoulder buttons; everything else is a face button.

Like the NES controller, each button only has one bit of state (pressed/unpressed) associated with it - there are no analog sticks/triggers like the GameCube controller's L and R.

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.

Another word for "button" mentioned in the official manual is "switch."^[1]
