      I downloaded the file that you put above. I put at /opt/retropie/emulators/reicast/bin/

      https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/reicast/reicast.sh you can try with this one

      Anyway, this is the content:

      #!/usr/bin/env bash
AUDIO="$1"
ROM="$2"
rootdir="/opt/retropie"
configdir="$rootdir/configs"

source "$rootdir/lib/inifuncs.sh"

function mapInput() {
local js_device
local js_device_num
local ev_device
local ev_devices
local ev_device_num
local device_counter
local conf="$configdir/dreamcast/emu.cfg"
local params=""

# get a list of all present js device numbers and device names
# and device count
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

    fi
    local counter=0

    done

    params+="-config input:evdev_device_id_1=0 "
fi
params+="-config input:joystick_device_id=-1 "
params+="-config players:nb=$device_counter "
echo "$params"
}

if [[ -f "$HOME/RetroPie/BIOS/dc_boot.bin" ]]; then

if [[ "$AUDIO" == "OSS" ]]; then

        Can you add some log to see what param value is use?

        for example, add :
        echo "$params" > /home/pi/testReicast.log
        before :
        if [[ "$AUDIO" == "OSS" ]]; then

        Launch reicast and open /home/pi/testReicast.log. it's look like pablo issue

          Here we go:

          config config:homedir=/home/pi -config x11:fullscreen=1 -config input:evdev_de$

            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

              More close...

              -config config:homedir=/home/pi -config x11:fullscreen=1 check if this exist : /sys/class/input/event0/device/js0
check if this exist : /sys/class/input/event1/device/js0

check if this exist : /sys/class/input/event4/device/js0
check if this exist : /sys/class/input/event5/device/js0

                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:

                alt text

                  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

                                          [input]
                                          evdev_device_id_1 = 2
                                          evdev_device_id_2 = 3
                                          evdev_device_id_3 = -1
                                          evdev_device_id_4 = -1
                                          evdev_mapping_1 = /opt/retropie/configs/dreamcast/mappings/controller_8BitdoNES30Pro.cfg
                                          evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/controller_8BitdoNES30Pro.cfg
                                          joystick_device_id = -1

                                          evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/controller_8BitdoNES30Pro.cfg

                                          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]
evdev_device_id_1 = 4
evdev_device_id_2 = 5
evdev_device_id_3 = -1
evdev_device_id_4 = -1
evdev_mapping_1 = /opt/retropie/configs/dreamcast/mappings/controller_Ultimarc_I-PAC_Arcade_Control_Interface.cfg
evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/controller_Ultimarc_I-PAC_Arcade_Control_Interface.cfg
joystick_device_id = -1

                                          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]
mapping_name = Xbox Gamepad (userspace driver)
btn_escape = 316

[dreamcast]
btn_a = 304
btn_b = 305
btn_c =
btn_d =
btn_x = 307
btn_y = 308
btn_z =
btn_start = 315
btn_dpad1_left =
btn_dpad1_right =
btn_dpad1_up =
btn_dpad1_down =
btn_dpad2_left =

btn_dpad2_up =
btn_dpad2_down =
axis_x = 0
axis_y = 1
axis_trigger_left = 2
axis_trigger_right = 5

[compat]
btn_trigger_left = 312
btn_trigger_right = 313 
axis_dpad1_x = 16
axis_dpad1_y = 17
axis_dpad2_x =
axis_dpad2_y =
axis_x_inverted = no
axis_y_inverted = no
axis_trigger_left_inverted = no
axis_trigger_right_inverted = no
axis_dpad1_y_inverted = yes
axis_dpad1_x_inverted = no
