Button Mapping
Decide what each button on your controller actually does in the game. The list shows every button and stick direction the game can understand, one row each, and you tell MustardOS which of your own buttons should send it.
Useful when a game's default layout does not suit you, when you are using a controller whose buttons sit in a different order, or when you want jump on a different button.

Visible Options
Face Buttons
Rows for A, B, X, and Y. Highlight one, press A, then press the button on your controller you would like to use for it.
Select and Start
Rows for the two small centre buttons, which many games use for pausing or bringing up a map.
Quick Tips
Press A on a row to set it, X to clear it so nothing sends that input at all, and Y to put it back to normal.
A row showing Macro: followed by a name is being driven by a macro. Turbo cannot be added on top of one, so change it from the Macros screen.
Cleared or remapped yourself into a corner? Reset Port on the previous screen puts every button on this player back to normal.
