      @Folly Your script works perfectly, the problem is the mame which uses some rather strange formats:

      pi@retropie:~ $ /opt/retropie/emulators/mame/mame -listmedia ep128
      SYSTEM           MEDIA NAME       (brief)    IMAGE FILE EXTENSIONS SUPPORTED
      ---------------- --------------------------- -------------------------------
      ep128            printout         (prin)     .prn
      ep128            cassette1        (cass1)    .wav  .flac
      ep128            cassette2        (cass2)    .wav  .flac
      ep128            cartridge        (cart)     .bin  .rom
      

      Instead of these most used formats: .com .tap .img .dtf

      I saw you covered the issue here: https://retropie.org.uk/forum/topic/30867/the-bewildering-case-of-the-enterprise-64

      I then tried to understand how to create an ad-hoc script starting from here: https://github.com/istvan-v/ep128emu, but there are some dependencies and commands to launch that I don't know how to implement in the script.

        Let's split up the topic first and talk about mame/mess first, agree ?

        I have an option beneath installing DEFAULT systems which is called systems with EXTRAS.
        Here you can find the line to install ep128 with basic21 and exdos + floppy drive.

        You can manually check how mame will react listing the media in the command :

        /opt/retropie/emulators/mame/mame -listmedia ep128 -exp exdos
        

        You will see that when adding -exdos a floppy drive is added.

        Make sure you add the proper bios files to you folders and it should do what you want.

          @Folly Thank you! Floppies work now! Out of curiosity, I saw that there are some games that require ISDOS, I loaded them but when I launched them (I used the load filename.com command), I got the "invalid file header" error, do you know if there is a solution to the error? Thanks again for your help.

            Can you paste the whole runcommand that is not working for you ?

              @Folly I explained myself badly, the script works perfectly and the rom is loaded, however for roms that do not have the automatic loader (e.g. "Zork 1 - The Great Underground Empire (1984)(Infocom)[req isdos].IMG" ) the machine prompt is opened directly, expecting a command, and I give it:
              :load ork1.com
              I write ork1.com and not zork1.com because if I execute the :dir command I get these 3 lines:
              ORK1.COM
              ZORK1.DAT
              ZORK1.TXT

                Ok, so summarised it means that when a disk doesn't contain any autoloader you load it manually and that works for you too, correct ?

                  Yes, that's correct, I have to load it manually, but even though the command seems correct, it gives me this error: "invalid file header"

                    The file says you need "is-dos" running on the ep128.
                    is-dos is explained on the internet as cp/m compatible os.
                    Look here :
                    https://en.wikipedia.org/wiki/Enterprise_(computer)

                    Edit :
                    I am trying to get it working but can take a while

                      I just had ZORK1 working.

                      My plain test mame command was :

                      /opt/retropie/emulators/mame/mame -rompath /home/pi/RetroPie/BIOS/mame\;/home/pi/RetroPie/roms/ep128 -v -c -ui_active ep128 -exp exdos isdos
                      

                      isdos is part if the softlist in ep64_flop and is the one to be loaded.
                      Then you have to switch the floppy from within mame UI to ZORK1.

                      Isdos works just like ms-dos you load zork1 just using the name, as you said ork1 :

                      A>ork1
                      

                      That should work.

                      I will experiment if I can add a second drive so I can make a line that will start with isdos adding the game in the second drive.

                        It's possible to load all in one command adding an extra floppydrive :
                        (used hash-names for softloading)

                        /opt/retropie/emulators/mame/mame -rompath /home/pi/RetroPie/BIOS/mame\;/home/pi/RetroPie/roms/ep128 -v -c -ui_active ep128 -exp exdos -exp:exdos:u1:1 35dd isdos -flop2 zork1
                        

                        or :

                        /opt/retropie/emulators/mame/mame -rompath /home/pi/RetroPie/BIOS/mame\;/home/pi/RetroPie/roms/ep128 -v -c -ui_active ep128 -exp exdos -exp:exdos:u1:1 35dd -flop1 isdos -flop2 zork1
                        

                        Would be nice if I could make a runcommand that is versatile so all software can be loaded with the same runcommand so it can be implemented in the script when installing the ep64/ep128 from the default.
                        Will have a look at that.

                          @Folly Great! I used your command to add 2 new lines:

                          lr-mess-ep128-basic21_exdos-isdos-flop = "/opt/retropie/emulators/retroarch/bin/retroarch --config /opt/retropie/configs/ep128/retroarch.cfg --appendconfig /opt/retropie/configs/ep128/retroarch.cfg.add -S /home/pi/RetroPie/roms/ep128 -s /home/pi/RetroPie/roms/ep128 -v -L /opt/retropie/libretrocores/lr-mess/mamemess_libretro.so 'ep128 basic21 -rompath /home/pi/RetroPie/BIOS/mame;/home/pi/RetroPie/roms/ep128/ -cfg_directory /opt/retropie/configs/ep128/lr-mess -c -ui_active -exp exdos -exp:exdos:u1:1 35dd -flop1 isdos -flop2 %ROM%'"
                          lr-mess-ep128-basic21_exdos-isdos-flop-autoframeskip = "/opt/retropie/emulators/retroarch/bin/retroarch --config /opt/retropie/configs/ep128/retroarch.cfg --appendconfig /opt/retropie/configs/ep128/retroarch.cfg.add -S /home/pi/RetroPie/roms/ep128 -s /home/pi/RetroPie/roms/ep128 -v -L /opt/retropie/libretrocores/lr-mess/mamemess_libretro.so 'ep128 basic21 -rompath /home/pi/RetroPie/BIOS/mame;/home/pi/RetroPie/roms/ep128/ -cfg_directory /opt/retropie/configs/ep128/lr-mess -c -ui_active -autoframeskip -exp exdos -exp:exdos:u1:1 35dd -flop1 isdos -flop2 %ROM%'"
                          
                          

                          Once the isdos was loaded (automatically) I changed the drive with the "b:" command, to be careful I executed the "dir" command and simply launched the "ork1.com" command without using the "load" and it worked! Thank you!

                            I updated my script to 265.21 and added code that will install the extras when installing from the DEFAULT.
                            Can you test it for me ?

                            (My advise is to backup your emulators.cfg first)

                                Thanks, good to hear.
                                I am playing with it a bit and I could add it for more drivers this way from EXTRAS.
                                I will see how it evolves.
