XBOX 360 controller controlling both players in supersmash

[dark shark]

Hi I am trying to play supersmash brothers melee with my cousin on the dolphin emulator. I have 2 wireless xbox 360 controllers. I am having difficulty playing 2 players for this game because Controller 1 is also controlling Controller 2, meaning everytime I move with controller 1, controller 2 is also moving. Can someone please help me

PROBLEM SOLVED, I had to put XInput/1 for Port # 2
