// Wii U Pro Controllers through SDL's HIDAPI Wii driver. No SDL_GamepadType
// singles them out, so they are picked by the name the driver gives them (see
// __PADSetDefaultMapping). Wii Remotes, with or without a Nunchuk or Classic
// Controller, are read by the game through KPAD instead and never get a
// GameCube mapping (the runtime hides those ports from PADRead).

// Nintendo's labelled layout: A on the right accelerates, B at the bottom
// brakes. SDL's Wii driver reports ZL/ZR as the LEFT_TRIGGER/RIGHT_TRIGGER
// axes, never as shoulder buttons, so they are left unbound here and picked up
// by aurora's default axis mapping (g_defaultAxes) the same way every
// analog-trigger pad's L/R is.
