        Finally fixed my problem... For some strange reason whenever I would copy a rom file onto my SD it will miss 1MB in size. So if rom file was 720Mb, it would copy 719Mb onto sd card makin the rom file unusable. I used terminal command 'cp' to copy the file and finally it works like a charm!

            I'm desperate.

            I have an Attract mode installation in a Pi3, and Reicast don't let me pass the date&hour screen. I changed the "reicast.sh" file for avoid the autoconfig (as I read in another post), and now reicast don't work (return automatically to the menu). So I decide to make an new installation with RetroPie clean install (without Attract mode) in another microSD. But now the Dreamcast emulator don't run even in the new installation.

            Clean install case

            • Clean install
            • Set controllers (IPAC 2)
            • I just copy the BIOS files.
            • Run Systemmanager.
            • Don't run. The emulator goes back to menu screen.

            Attract mode case

            • I save the original reicast.sh original file from the clean copy
            • I overwrite the file
            • I run Dreamcast emulator and it doesn't work.

            I use Sftp for copy the files to the Pi. I supose had good BIOS files because I saw the date & time screen before.

            What can I do?
            Thanks!

              Hello,

              It can be the same issue of pablo.

              1. In attract mode case. When you say "it doesn't work", what do you mean?
                You can pass the date/hour screen?

              2. when you can't pass date/hour screen, can you move the cursor? I can be a controller issue. Maybe it's not config to work with reicast. Can you check on the config directory of reicast if you go the good configuration file for your controller? (/opt/retropie/configs/dreamcast/mapping)

              3. Your controller is on : /dev/input/ and have a name starting with "js"?

                Hi @Hyell

                1- Doesn't work = emulator don't run. Since I changed the reicast.sh file, the emulator don't start. I selected a game or Systemmanager, and then return to main screen. This is now my priority. I can't go to the date/hour screen!

                2 - I can't move the cursor.

                I made some config files with and without spaces:

                alt text

                (I put "/" for keep the text together in the quote)

                [emulator]
                mapping_name = Ultimarc IPAC 2 Ultimarc IPAC 2
                emu_btn_escape = 45
                /
                [dreamcast]
                btn_a = 56
                btn_b = 42
                btn_x = 29
                btn_y = 57
                btn_start = 44
                btn_dpad1_left = 105
                btn_dpad1_right = 106
                btn_dpad1_up = 103
                btn_dpad1_down = 108
                /
                [compat]
                btn_trigger_left = 2
                btn_trigger_right = 6

                This is the emu.cfg (I put "/" for keep the text together in the quote)

                [audio]
                backend = oss

                /
                [validate]
                OpenGlChecks = 0

                3 - This is how looks like my /dev/input/ It's ok?

                alt text

                Now I see the input list... maybe I have to rename the config file to "Ultimarc_IPAC_2_Ultimarc_IPAC_2_9" ???

                Anyway, I can't run the emulator!!

                Thanks for your help :-)

                  Ok.
                  Can you copy here your reicast.sh file please? We will see why reicast don't start.

                  And we will check your controller after.

                    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:

                      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

                          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

check if this exist : /sys/class/input/event3/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:

                                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))

                                    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)
2: Ultimarc IPAC 2 Ultimarc IPAC 2 (/dev/input/event2, usb-3f980000.usb-1.5/input0)

4: Ultimarc IPAC 2 Ultimarc IPAC 2 (/dev/input/event4, usb-3f980000.usb-1.5/input2)
5: Ultimarc IPAC 2 Ultimarc IPAC 2 (/dev/input/event5, usb-3f980000.usb-1.5/input3)

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.

                                            No way. Still without controls...
