i have the exact same problem.
some people wrote, that when you get the controllers to work individually all you have to do then is to “parse the second controller”. i dont really get what it means. i am confused because various tutorials about this matter tell you to edit config files, that are either not there at all or are named differently or are at a different place. it seems the tutorials all relate to certain versions of retropie and obviously there were changes made to the location and naming of config files.
Raspberry Pi: Connecting multiple PS3 controllers via bluetooth
i tried the above tutorial among others and i dont get where i should put the config lines for the second controller. what i did find was the declaration of the controllers index. i uncommented these lines in, without success..
id like to hear someone explaining it on the most current version. that would be seriously cool!
im so amazed by the speed of the rpi2 and the ability to emulate all those games from the past. thank you for that neat software project! :)
