            Let me know when you come to Rio de Janeiro and we'll drink some Caipirinhas and try to find some arcade to play Street Fighter or something. :)

              @meleu Don't make any jokes! My company got's a branch office in south america. For three or four weeks a company pal was in Rio to sell goods and he visited his girlfriend there. So it could happen I'm in :) It's unlikly but never say never :)

              SFII? I was more addicted to MK! But for the Caipis sake :)

                You could try something like

                sleep 5
                while [$(pidof retroarch)]
                    do
                    *script to scroll once*
                    sleep 5
                done
                

                Lauched in background by runcommand-onstart.

                    @cyperghost it's not a joke! Consider yourself invited. Any game is fun with enough alcohol and friends. :-)

                      Let's get back on topic...

                      @daveyman123 usually your python script scrolls the text only once or keeps looping the text?

                        @sano I think it isn't a matter of the retroarch-PID more that the script does anyting.
                        But it's a nice catch to end a process by watching the retroarch-PID.

                        @meleu and me descriped also ways to terminate a running script :)

                        And thanks for the invitation. It's very unlikely that I ever enter brazil, but as I said never say never and market development changes quickly. My next stops will be more east .... romania, bulgaria, russia, belarussia...

                          scrolls the text once. I would like it to eventually loop. but right now it stops as soon as the game actually launches

                            @daveyman123 got it. I'll try something when I get home (it means 4 or 5 hours).

                              I may have it figured out by then ;)

                                @meleu @daveyman123 It's late here - going to sleep.
                                Good night mates

                                @daveyman123
                                That's the wrong intention. The script should do the loop not a bash file. The bash file should only tell changes. Because you always load the python interpreter again and again and this will waste resources and even the python language gives you much much controll over strings. So I would rather use python intead of bash.

                                @meleu will certainly find an easy and working solution ;)

                                    I will look into cyperghost's loop.sh example again and see if that works to put the python script in there

                                    The loop example is useless. You should look the runcommand-onstart.shand how scripts are called and running in background. If you were able to readout files you can simply write the romname via echo $3 to a file or you can directly call the python script with $3 command.

                                    I think @meleu will do a nice job but meanwhile you can also try to find a solution. I'm 100% sure you find one!
                                    Good night

                                      @daveyman123 Here are some ideas to let you find the solution yourself...

                                      Use this code as inspiration for your runcommand-onstart.sh:

                                      # getting the rom name with no full path and no extension
                                      rom_name="$(basename "${3%.*}")"
                                      
                                      # running the python script in background
                                      sudo /path/to/python/code.py "$rom_name" &
                                      

                                      This one as inspiration for your runcommand-onend.sh:

                                      # killing the python script
                                      sudo pkill -f "/path/to/python/code.py"
                                      

                                      And this one as inspiration for your python script:

                                      #!/usr/bin/python
                                      
                                      # I don't know if it's right, just used @daveyman123 code as example
                                      from UHScroll import *
                                      import unicornhat as unicorn
                                      
                                      import time sys
                                      
                                      while True:
                                          # I have no idea if this command is right, I just used @daveyman123 code as example
                                          unicorn_scroll(sys.argv[1], 'white', 255, 0.2)
                                      
                                          # I have no idea if 5 seconds is OK, adapt it to your needs
                                          time.sleep(5)

                                        there is still the problem of (i dont know if i mentioned it) the unicorn only scrolls through ONCE (even if i include a loop in python) then it will play a random sequence of lights. I.E. it reads "JIM" or "GOLDEN" in "GOLDENEYE". But as soon as the game launches it freezes or plays random lights.

                                        My fear is it has something to do with the pins being messed with by retropie. I have not tried to replicate the problem on raspbian.. but I may have to try that.

                                        What I have tried:
                                        making sure audio isnt interfering with the unicorn hat pins (i.e. setting the audio output to hdmi)
                                        and obviously have tried making the python script run in the background
