    So i’ve hooked up 2 NES controllers to my GPIO adapter and everything within Emulationstation seems to be working fine with the controllers. When I map the controllers, I’m able to map the B button and also use it while navigating the interface, but as soon as I launch a game the B button no longer responds.

    Anyone have any Ideas as to what could be wrong? I noticed some info on this page https://github.com/retropie/RetroPie-Setup/wiki/gamecon_gpio_rpi about problems with some controllers not able to work properly at 3.3v. Is this what my problem is, or is something else going on here?

    This is for a school project so I’ll be spending the next week or so (if I have to) in the forum trying to figure this out

    Bumping this thread as I’m dying to get some help here within the next few days hopefully. I know there’s gotta be somebody out there that can save me!

    I am also having the same problem. I just spend a few days trying to figure out this GPIO nightmare and this is the last thing.

    — went here: /opt/retropie/emulators/RetroArch/configs

    — change b button to “3” and a button to “1”

    input_device = “SNES-to-Gamepad Device”
    input_driver = “udev”
    input_b_btn = “3”
    input_y_btn = “2”
    input_select_btn = “6”
    input_start_btn = “7”
    input_up_axis = “-1”
    input_down_axis = “+1”
    input_left_axis = “-0”
    input_right_axis = “+0”
    input_a_btn = “1”
    input_x_btn = “3”
    input_l_btn = “4”
    input_r_btn = “5”

    works now

    Thanks a lot, that did the trick. I figured it had something to do with that file, I just couldn’t put my finger on it.

    Hello guys!
    Can you post an image of your GPIO with the NES Controllers plugged in?

    I’m trying to do that since Saturday, but my controller dont work. It detects, but dont work.
    Do you use SNESDev?

    thanks in advance
