I have build a NES into a RetroPie console using RP2.
I have wired in the 2 controller ports of the NES and also have used 2 PS3 controllers with Emulationstation.
What I am having issue with is when ever the NES controller ports are plugged into the USB ports of the RP2 they are considered Controllers 1 and 2 and my PS3 controllers are connected as 3 and 4.
I need a way other that unplugging the ports to have my PS3 controllers connect as players one and two.
Any help would be greatly appreciated.
Thanks.
