      @pablo you go players:nb= but you don't have any informations for this.

      try to add :
      [players]
      nb=1 (or more)

      in your emu.cfg file

      [EDIT] In reicast.sh you got a function "mapInput() try to change this line (at the end of function) :
      params+="-config players:nb=$device_counter "
      to
      params+="-config players:nb=2 "

              Thanks @Hyell, I realised what was causing this now. When I was doing the testing I only had my keyboard plugged in and my bluetooth controllers were off. It would seem that the player count ignores my keyboard and thus was making Dreamcast bomb.

                  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

                          btn_trigger_right = 6

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

                          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

                                  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

                                      More close...

                                        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
