      Ok, this part is not correct. You got an issue with your mapInput() function.
      I think this part don't work with your controller :

      for js_device in /dev/input/js*; do
        js_device_num=${js_device/\/dev\/input\/js/}
        for ev_device in /dev/input/event*; do
            ev_device_num=${ev_device/\/dev\/input\/event/}
            if [[ -d "/sys/class/input/event${ev_device_num}/device/js${js_device_num}" ]]; then
                file[$ev_device_num]=$(grep --exclude=*.bak -rl "$configdir/dreamcast/mappings/" -e "= $(</sys/class/input/event${ev_device_num}/device/name)")
                if [[ -f "${file[$ev_device_num]}" ]]; then
                    #file[$ev_device_num]="${file[$ev_device_num]##*/}"
                    ev_devices[$ev_device_num]=$(</sys/class/input/event${ev_device_num}/device/name)
                    device_counter=$(($device_counter+1))
                fi
            fi
        done
    done

      Can you add more logs? We will see if all file of your controller is OK.
      (I think this code is OK) :

      for js_device in /dev/input/js*; do
        js_device_num=${js_device/\/dev\/input\/js/}
		echo "$js_device_num = $js_device_num" > /home/pi/testReicast.log
        for ev_device in /dev/input/event*; do
            ev_device_num=${ev_device/\/dev\/input\/event/}
			echo "ev_device_num = $ev_device_num" > /home/pi/testReicast.log
			echo "check if this exist : /sys/class/input/event$ev_device_num/device/js$js_device_num"
            if [[ -d "/sys/class/input/event${ev_device_num}/device/js${js_device_num}" ]]; then
				echo "Now check if this exist : /sys/class/input/event$ev_device_num/device/name"
                file[$ev_device_num]=$(grep --exclude=*.bak -rl "$configdir/dreamcast/mappings/" -e "= $(</sys/class/input/event${ev_device_num}/device/name)")
                if [[ -f "${file[$ev_device_num]}" ]]; then
                    #file[$ev_device_num]="${file[$ev_device_num]##*/}"
                    ev_devices[$ev_device_num]=$(</sys/class/input/event${ev_device_num}/device/name)
					echo "Add for controller : /sys/class/input/event$ev_device_num/device/name"
                    device_counter=$(($device_counter+1))
                fi
            fi
        done
    done

          One more thing. In case you see more devices (I don't know), this is because I reconnect the trackball to the Raspberri Pi 3.

          Now the input list is:

            Can you type :
            cat /sys/class/input/event2/device/name on raspberry console please?

            I think issue is on this part :

            if [[ -f "${file[$ev_device_num]}" ]]; then
                    #file[$ev_device_num]="${file[$ev_device_num]##*/}"
                    ev_devices[$ev_device_num]=$(</sys/class/input/event${ev_device_num}/device/name)	
                    device_counter=$(($device_counter+1))
                fi

                FYI, reicast-joyconfig give me this values:

                0: Barcode Reader  (/dev/input/event0, usb-3f980000.usb-1.2/input0)
1: Barcode Reader  (/dev/input/event1, usb-3f980000.usb-1.2/input1)

7: Apple, Inc Apple Keyboard (/dev/input/event7, usb-3f980000.usb-1.4.2/input1)

                I checked that ID number 3 is the good one for use my controls (joystick and buttons)

                  reicast.sh don't count correclty your device.
                  Maybe it's because of space on your name device.
                  you have create a "Controller_Ultimarc IPAC 2 Ultimarc IPAC 2.cfg" file
                  but script never found the good file.

                  so he never add a controller

                  can you try to change these line :

                  params+="-config input:joystick_device_id=-1 "
params+="-config players:nb=$device_counter "

                  By

                  params+="-config input:evdev_device_id_1=3 "
params+="-config input:joystick_device_id=-1 "
params+="-config players:nb=1 "

                      Ok.
                      You can try to add quote on emu.cfg

                      evdev_mapping_1 = "/opt/retropie/configs/dreamcast/mappings/controller_Ultimarc IPAC 2 Ultimarc IPAC 2.cfg"
                      If it's a blank issue it can be better.

                          if you use 'evtest' commande can you use your controller with ID 3?
                          And is ti the correct value on your controller.cfg file?

                          In a second time, can you test with ID 2 when you launch reicast?

                            I used the values from reicast-joyconfig

                            Yes, I can use evtest with ID 3. I recibe this when I push A button:

                            Event: time 1466183037.124242, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e2
Event: time 1466183037.124242, type 1 (EV_KEY), code 56 (KEY_LEFTALT), value 0

                            As you can see, is the same code from reicast-joyconfig

                            [dreamcast]
btn_a = 56

                            ID 2 don't work in reicast-joyconfig. Neither evtest!

                              Hum, can you change emu.cfg to use another config file for your controller? A file without blank?
                              Or maybe try with another controller, just to validate one configuration?
                              I must admit that I have no more ideas :/

                              I will check my own configuration to see if we have miss something.

                                Thank you for help, I will check again everything.

                                If the file is "controller_NAMECONTROLLER.cfg"

                                This "NAMECONTROLLER" is the same name that "Mapping Name" inside the file? And the ID of the controller?

                                For example, can I name it "controller_pad.cfg"?

                                So inside controller_pad.cfg :

                                [emulator]
mapping_name = Ultimarc IPAC 2 Ultimarc IPAC 2

                                or

                                [emulator]
mapping_name = pad

                                Thanks again.

                                  It's the name of the pad :

                                  mapping_name = Ultimarc IPAC 2 Ultimarc IPAC 2

                                  and you can have blank.

                                  but the name of the file is not really important.
                                  If you have a file named :
                                  controller_test.cfg

                                  You just have to put the same name file on emu.cfg

                                  Have you test with a file named without blank?

                                    Yes, I used "controller_Ultimarc.cfg" and nothing.

                                    Maybe this could help?

                                    the controller config part of my emu.cfg looks like this

                                    Wow. I can't believe it. I made it work. I took the spaces out of my mapping file and replaced them with underscores, then commented out the automap line in the .sh file as you instructed. Then I updated my emu.cfg adding this:

                                    [input]

                                    and it actually works. Crazy taxi has a few audio problems on the P3, but it actually worked. Thanks for your help!

                                      it's the same test when you use controller_Ultimarc.cfg
                                      can you try to edit your controller_ultimarc.cfg to match with this :

                                      [emulator]

                                        Nooooothing. Incredible. I'm completely lost. I put here the main archives if you need look something else.

                                          Ok... I used a DualShock 4 and works awesome.

                                          It's ok, but the idea is use the cabinet controls. At least I can confirm that all the configuration it's ok.

                                          Maybe the thing is located in the IPAC imput/event things.

                                          :-)

                                            It's really strange.
                                            I think issue is on reicast code source.

                                            I found this, but they don't give solution :
                                            http://libretro.com/forums/showthread.php?t=5275

                                            and this :
                                            https://www.reddit.com/r/RetroPie/comments/42a3rd/can_i_run_mupen64plus_or_reicast_with_the/?
                                            put IPAC 2 on gamepad position...
                                            Can you try this?
