        Yes, Fol! You are quite right, those games work now. I am enjoying exploring the BBC! I definitely had Citadel as a kid, I played that yesterday.

        Edit: Stunt Car Racer glitches for me when I get into the actual racing sections. Prince of Persia is fine.

          Are you aware of the magic scraper line ?
          Goto your directory where the files have to go then (creates with subdirectory's) :

          wget -c -r https://<the website> -A ssd

          Or

          Goto your directory where the files have to go then (creates without subdirectory's) :

          wget -c -r https://<the website> -A ssd -nd

          I am running this on a site now, very clever!

            @adambegood What the status of the ROM distributed via the above site ? Do they have a free/shareware license atttached ? If unsure, then please remove the link to the site.

              @mitu I think it is okay, but for safety I have removed.

                  @folly Is that xmaster as a core name or not?

                  I don't get the option to select the disk for this game when I select "xmaster". Is there something else I should have installed for this? Arggg

                    You don't have to select within xmaster.
                    Just boot the game from emulationstation.
                    Then press a key, so you can change the emulator and choose xmaster.
                    Then launch.
                    If you don't see this, then you haven't installed the correct module-script.

                      @folly I know this sounds mad, but I can’t select <cmd line> or whatever that option was called with that game. I can with other games on the core, but not this game.

                      I am using xmaster, yep.

                      I don’t understand!

                      Edit: And if I press Ctrl-F12 without altering anything it runs “Twisted”.

                        Do you have these lines in /opt/retropie/configs/bbcmicro/emulators.cfg ? :

                        xbeeb = "XINIT:/opt/retropie/emulators/b-em-pico-pi/xbeeb.sh %ROM%"
default = "xmaster"
xmaster = "XINIT:/opt/retropie/emulators/b-em-pico-pi/xmaster.sh %ROM%"

                        Do you have these files in /opt/retropie/emulators/b-em-pico-pi ? :
                        retropie.pkg xbeeb xbeeb.sh xmaster xmaster.sh

                          And yep, I do have those. I can select <cmd line> with other games in xmaster, but not this one (or Prince of Persia I think)! I'll have a look in the morning again...

                            Looks good.

                            Ok, so it works with others, but not with Prince Of Persia, correct.

                            This game works fine here.

                            It can be two problems, I think :

                            • Did you use the .ssd file ?
                              (xmaster doesn't work with .zip)

                            • Do you have spaces in the directory or the .ssd file ?
                              (I did a fix on the spaces problem, it is updated on github)
                              (wget the module-script again, and update in RetroPie-Setup or do it faster with the commands beneath without the RetroPie-Setup)

                            Fast alternative to fix only this problem for now :
                            (second line does only the configure part, without compiling etc)

                            wget -nv -O /home/pi/RetroPie-Setup/scriptmodules/emulators/b-em-pico-pi.sh https://raw.githubusercontent.com/FollyMaddy/RetroPie-Share/main/00-scriptmodules-00/emulators/b-em-pico-pi.sh
sudo /home/pi/RetroPie-Setup/retropie_packages.sh b-em-pico-pi configure

                              I've sussed it out (realised when I was in the shower), before I read your message - superb deduction though!

                              I'd changed the title to "Prince of Persia.ssd" to make it easier to scrape. The spaces stopped the .ssd picking up in the emulator.

                              Thanks for the script to take out spaces, I only had this for two games though.

                              Sorry!..

                              Edit: I'll use your command lines to resolve the issue also, thank you.

                                Nice, we improved it on the way !

                                Now we can play a little bit more.

                                I should add a help to the module-script.

                                  Please could someone help? I’ve installed this as per instructions with the code and installed via Retropie setup so my roms now show up in Emulation Station. However when I run any game it just goes back to the menu. I’ve installed the files in BIOS/mame and have ssd games in the roms/bbc-micro

                                  I’ve tried run command using x-master but no joy :(

                                  Any help much appreciated!

                                    @mrnoholster So does X-Master load okay? Have you tried Shift-F12 to run the disk?

                                      We have it working, so it should work for you.

                                      I’ve installed this as per instructions with the code and installed via Retropie setup so my roms now show up in Emulation Station.

                                      Did you use these insructions ? :

                                      • -1- link to post for lr-mess/mame
                                      • -2- link to post for xmaster and xbeeb of b-em

                                      However when I run any game it just goes back to the menu. I’ve installed the files in BIOS/mame and have ssd games in the roms/bbc-micro

                                      You are talking here about option 1, the lr-mess/mame, because you need bios files for that one.
                                      Your BIOS files are :

                                      • BIOS/mame/bbcb.zip
                                      • BIOS/mame/saa5050.zip

                                      Your roms for these older instructions still have to be in :

                                      • roms/bbcb/<your_roms.ssd>
                                      • roms/bbcb/<your_roms.zip>

                                      When you boot the rom, you have to press a key when the RetroPie load screen comes up.
                                      Now you can select an emulator.
                                      Make sure you select one with the (-flop) option.

                                      I you get a black screen and if it goes back to emulationstation you have to check your /dev/shm/runcommand.log with a texteditor.
                                      Most likely that you can find the problem here.
                                      Most common are the bios files not found.
                                      If you see something like not found tried in, most likely you are missing bios files.

                                      Option 2, with xmaster, should be far easier.
                                      Make sure your roms files are in :

                                      • roms/bbcmicro/<your_roms.ssd>

                                      What does your /dev/shm/runcommand.log say ?

                                          In this whole post I only talk about xbeeb and xmaster that come from the b-em fork.
                                          Just to make sure we don't mix up things, othewise it will get too confusing.

                                          I dug a bit into this.
                                          It seems to be that your rpi doesn't support some things.
                                          Which type of raspberry pi are you using?

                                          It also looks like you have a bad compiled binary.

                                          Sadly this is beyond my knowledge.
                                          You could try to install again though, and see if it will work after a second install.
                                          If this doesn't work for you it is sensible to remove it and accept that this version doesn't work for you.
                                          Then it's better to focus only on lr-mess/mame

                                          My BIOS files are /home/pi/RetroPie/BIOS/mame/bbc_acorn8271.zip
                                          /home/pi/RetroPie/BIOS/mame/bbcb.zip
                                          /home/pi/RetroPie/BIOS/mame/saa5050.zip

                                          My .ssd roms are located in /home/pi/RetroPie/roms/bbcmicro/

                                          For the b-em install there is no need to use bios rom files and the ,ssd roms are in the correct place.

                                          Try again to install.

                                          If it doesn't work we move to lr-mess/mame in a later post.

                                            Today, I also installed the b-em-pico emulator following your instructions , but I get exactly the same error message.
                                            I tested on Pi 2 and P3 A+, with a fresh latest RetroPie image.
                                            Has anyone successfully run the emulator on P2/3 models, I guess it's not Pi4 only, if it's already made for the Pico version as well.
                                            Maybe someone has an idea, what does this error message really mean and what is the exact installation procedure if we missed something ?
