Wiimote Nunchuck support?

Does Retroarch support Nunchuck?

As I found out RetroArch uses Joypad1 for Player 1 and Joypad2 for Player 2 and so on. When using Nunchuck, the new device is registered as Joypad2, as the Wiimote itself is Joypad1. So it currently doesn’t work?

Should there be a feature to merge the nunchuck compatibilty with the wiimote?
