      I've not run into that error when installing the gamecon driver... It asks you if you want to install the kernel stuff at first and you just say yes and it all installs fine... Did you not answer that question?

      I've installed the gamecon drive many times (including the current 4.0.3 version) and never had any issues...

        @jsawhite That's the error I get when accepting the kernel install. I'll try a retropie build soon. When I find an SD card

          @lilbud CEC works in Kodi already on RetroPie. The Pipplware people have got CEC working in ES and the linux menus with their distribution. It's built along-side RetroPie.

            @Rookervik can you change PiPplware to English? If so I might try it out on my 2nd microSD card.

              @Rookervik I had similar issues with my GPIO controller driver after upgrading to 3.7. The answer in my case was to install the kernel headers using:

              sudo apt-get install raspberrypi-kernel-headers

              Then run the setup and it completed fine.

                @simonster Thank you, I will give that a try in just a minute.

                @backstander Yes Pipplware defaults to English in the menus and ES, but in Kodi you need to change your locale. Look for screenshots of Kodi's menus to find your way there.

                Also, I have done a lot lot LOT of prodding on this SNES Controller PCB and compiled some information I have found on the internet. So I jumped in Illustrator and made this SNES Controller PCB Diagram. It should be correct. I used my multi-meter and testing everything twice. But I can still screw up.

                From here I will have an easier time trying to keep pins in order while looking for GPIO pin numbers.

                  @simonster No dice. Ran your command, rebooted, tried to install the Gamecon drivers... still the same error. No linux-headers package could be found for your kernel version...

                  So I suppose I'll try that version 4 of RetroPie and see if it works. I've tried every combination of GPIO pins the internet has to offer me along side the SNESDev driver running with SNESDev & then running jstest /dev/input/js0 or 1 or 2 or 3

                  I can't find concrete instructions using either Gamecon or SNESDev anywhere, showing exact GPIO pins to use and an installation procedure.

                  ALSO: if any of you can tell me exactly which driver you're using (SNESDev or Gamecon or what...) and exactly which GPIO pins you're using for the SNES Controller (Clock, Latch, Data 1, Data 2) that would be amazing. LOL

                    I can't find concrete instructions using either Gamecon or SNESDev anywhere, showing exact GPIO pins to use and an installation procedure.

                    It is in the wiki page

                    Gamepad3 = GPIO4 = Physical Pin07
                    Gamepad4 = GPIO7 = Physical Pin26
                    Gamepad5 = GPIO2 = Physical Pin03
                    Gamepad6 = GPIO3 = Physical Pin05

                    ALSO: if any of you can tell me exactly which driver you're using (SNESDev or Gamecon or what...) and exactly which GPIO pins you're using for the SNES Controller (Clock, Latch, Data 1, Data 2) that would be amazing. LOL

                    To install from Emulation Station go to RetroPie .

                    1. RetroPie Setup
                    2. Manage Packages
                    3. Driver
                    4. gamecondriver

                    Make sure you update installed packages first. The driver will give you a warning when you try to install.

                    It comes with an option to permanently enable configuration for two SNES controllers using GPI04 and GPI03. (which would be pin#7 and pin#5.)

                    Clock = pin#19
                    Latch = pin#23
                    Power = pin#01
                    Ground = pin#06

                    Note both players Clock/Latch go to the same Pin#.

                      @SirBilly This is some great information! I went to the Wiki but didn't even see this.

                      Updated the Setup Script and was welcomed to the new install/manage menus. Found the gamecon and tried to install it again and it failed. I am working on getting a SD card and 4.0 RetroPie image set up. I don't want to wipe a 64 gig SD card with (so far) perfectly set up RetroPie unless I know it's going to work.

                      Also, it would be great to update the information on the Wiki to modern Raspberry standards. The GPIO pinout is for the old 20 pin GPIO and you would have had to jump on the RetroPie train very very early to have that Pi. Once I get this working I will make a very easy-to-follow instruction set. :D

                        SUBARASHII!!!! Updating to RetroPie 4.0 (and losing all my sexy pipplware stuff) fixed the Gamecon install error and once installed, took me by the hand and got my controllers working. I might try to see if someone can help me get Gamecon installed on my 3.7 RetroPie so I don't have to start over, completely. Have way too much custom stuff to lose it all.

                        Thank you to everyone that gave me pointers. Gamecon was the cure. And updating RetroPie, I guess.

                          I was running snesdev for a while, and reading up on gamecon and this thread, I wanted to try the gamecon driver and re-soldered my points accordingly. The gamecon driver saw my two snes pads and set them up without any warnings, but only one button from each controller is detected in ES. Anything extra needed to do? I checked my connections with a multimeter so that's not the problem. Controller port is getting the 3.3v. I'm running 4.0.2 clean install. I used the instructions @SirBilly provided

                          Update: Fixed my problem. The gauge of wire was just too thin. Works perfectly with an ide cable...well almost perfect. It doesn't work on the retropie-setup area or when you need to press a button to alter a game's setting right before loading it. No big deal, i guess. I can use a kb for that. Now my pi shuts down much faster without the snesdev driver.

                            I de-soldered the ports on the controller plate and made a layout, can anyone check if this is correct? Why does the comment above and wiki say to wire it to 3.3v while the controller needs 5v? I already have a RF module wired up to the red pin on the picture. I will get some rainbow jumper wires and solder them directly into the holes.

                              @denisuu Because it runs fine with 3.3v. I also fixed my issue with the pad working in retropie setup. I had to set the controller to Player 1. If you have any issues, please read the guide: https://github.com/retropie/retropie-setup/wiki/GPIO-Modules#gamecon_gpio_rpi

                                  I took some parts out of a old computer (header pins & audio connection cable) and soldered them onto the SNES plate. I used the recommended GPIO setup from the gamecon installer.

                                  But only button A is working on player 2. I'm pretty sure my soldering is good, and I suppose the wire thickness is also ok since the original ribon cable is very small. I read something about the 3 different revisions of controllers.

                                  The question is what can I do about it?

                                    @denisuu You need to bridge both clocks for both pads to work. I was having issues when I was using thin wires. I'm using whatever thickness IDE cables are.

                                      Yea both clock's are bridged I checked all connections in the front ports with the RPI GPIO pins and the wiring is good. But when I push B it shows as if I push all buttons at once in jstest. IDE cables are very thin for sure these wire's are thicker. But maybe the cable is too long it's 67cm.

                                      I will reinstall retropie, find thicker wires and try again.

                                      Controller 2 doesn't want to do anything at all I tried (GPIO7=Pin26 or GPIO3=Pin05)
                                      With gamecon_gpio_rpi map=0,0,1,1,0,0 and 0,0,1,0,0,1...

                                        I'm using the default config retropie has for the gamecon driver which is 2 snes controllers. My wires are around half as long as of yours.
                                        Pin1=3.3v
                                        Pin5=D2
                                        Pin6=GND
                                        Pin7=D1
                                        Pin19=C1/C2
                                        Pin23=L

                                          That works thanks!! It's a completely different layout then the Wiki and driver installer suggest tough. Also it turned out one of my controllers just isn't working :P

                                            The gamecon installer pinout is almost correct except for the player pins need to be switched around. No need for a tutorial but ok...
