Emulator

What's the problem?
Today we used 3 real Wiimotes and one USB Gamepad to Play New Super Mario Bros. When restarting the game the order of the Wiimotes (see LEDs on the Wiimotes) changed several times and sometimes we where only able to play with 3 Players. Sometimes even two Wiimotes showed that they were connected as Player one.
USB Pad was connected as Emulated Wiimote 4

My suggestion there should be a clear one to one mapping between controllers(MAC address/USB ID) and the port that it is connected to.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"): R7567

(optional) Dolphin version that does not have the problem:

Operating system and version: Windows 7
32-bit or 64-bit: 64-bit

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"): SMNP01

Build command-line (not on Windows):

Was the ISO a plain dump from disc, compressed and/or scrubbed?
