    Can you see in your last log in /home/pi/RetroPie-Setup/logs ?
    Perhaps there is a clue on why the binary isn't there.

      I couldn't see any obvious errors but my stretch image is old and i've abused it with tinkering

      I'm currently updating my buster image via retropie setup
      give me an hour for the updates to complete (which i should have done in the first place) and i'll test again

      apart from the binary not being copied across (which is probably more to do with my setup rather than your script) everything seems good
      the only 'quirk', as compared to installing other emulators, is setting cea=17 to get fullscreen

        sorry this is taking longer than expected - updating buster killed my audio and I haven't found the correct solution yet
        however, the installation script runs smoothly and seems to work as expected
        exits cleanly with ctrl+c
        keyboard input works
        not sure about audio yet but I don't think there will be a problem

        nice work :D

          Sounds good :-)

          Take your time, no problem !

            thanks for your patience
            I can't seem to get past the no audio issue - other emulators are fine, it's only b-em and electrem that are being awkward (they are fine on stretch, so no doubt i'm missing some buried setting since pulseaudio was introduced)
            can you get audio on buster?
            has anyone else tried the script??

              tried again with a fresh image (worthwhile exercise) and everything is working nicely apart from when you exit the emulator there will be a permission error
              unable to save CMOS file /opt/retropie/emulators/b-em-allegro4/cmos.bin Permission Denied
              edit
              *uninstalled /reinstalled now i can't replicate the error - it just works :D

                  Thank you for your efforts today
                  now pi 3 owners can enjoy the beeb
                  i've had the wireframe animation from the master version of elite running for about two hours now with no temperature warnings or crashes (3b+ in a megapi case with no cooling fans) - I think it's ready for people to try

                      Hi,
                      before I signed up I had a look at your electron script thinking I could adapt it for b-em
                      then realised it's still a bit beyond my current level (I'm self-taught and have gaps in my knowledge)
                      maybe i'll get there in a year or 2

                        Aha, Let me know when you are ready.
                        You could make great stuff, I think ;-)

                            Nice job !

                            If you want to, you can also use some of my svg's.
                            Electron is in there too. (but it's from the carbon theme)

                              Thanks for the offer - themes are getting tricky with so many new systems being added
                              which brings me nicely to - the acorn atom. Hoglet released a version of atomulator called Optima for the pi.
                              I couldn't get it to compile but there was a release binary V4 that just works (it does include some software on an emulated eMMC so i'm not sure about posting a link? - but it is from the usual acorn forum)
                              I'll try to spend some time playing over the next couple of days to see if it's worth bothering with

                                Well perhaps I can compile.
                                Will have a look this week.

                                Edit :

                                It's possible to compile !
                                Download the source from and extract :
                                https://github.com/hoglet67

                                Go into the src directory of the Atomulator source.
                                Do :

                                make -f Makefile.linux
                                

                                The binary will be placed next to the windows exe binary.
                                ( 1 directory up )

                                  got it compiled! - - ?why don't they put a Makefile.linux in the linux versions?
                                  this is not an easy machine to use :( - it's not bad with the emmc just some of the keymappings seem off

                                  at best I could see this as a 'curiosity' maybe in retropie's ports section - i'm guessing the user would have to find the eMMC files for themselves

                                  certainly a 'niche' machine
                                  here is the precompiled version I found in the forum - i've removed the software from the mmc folder but recommend you find Atom Software Archive V11 and add it back in - this gives a more 'out of the box' experience
                                  then again, as a system, maybe it's just not meant for retropie?

                                    Indeed, never grew up with Acorn machines.
                                    New for me too.
                                    This one seems quite odd when having the first look at it.

                                    at best I could see this as a 'curiosity' maybe in retropie's ports section - i'm guessing the user would have to find the eMMC files for themselves

                                    I don't think it belongs in a port section.
                                    It's just a regular emulator.

                                    certainly a 'niche' machine
                                    here is the precompiled version I found in the forum - i've removed the software from the mmc folder but recommend you find Atom Software Archive V11 and add it back in - this gives a more 'out of the box' experience
                                    then again, as a system, maybe it's just not meant for retropie?
                                    https://www37.zippyshare.com/v/bKj7nOKo/file.html

                                    I think the binary is now obsolete.
                                    Is there any difference with the compiled file ?
                                    You can compare with sums, for example :
                                    sha1sum <file>
                                    If the sums for both files are the same then there is no difference.

                                    Will try to find the software.
                                    Hope I can load some but I am not so sure yet ;-)

                                      the file sizes are different
                                      'Atom Software Archive V11' should get you all you need
                                      shift + f12 to load the menu
                                      < & > to navigate

                                      the binary is not without issues - launching from terminal gives
                                      'pi@retropie:~$ /home/pi/Programs/atomulator/Atomulator
                                      Atomulator: /home/pi/allegro-5.1.8/addons/font/text.c:298: al_get_font_line_height: Assertion `f' failed.
                                      Aborted'
                                      yet double clicking on the binary launches straight into full screen

                                      a private message function would be useful for the forum

                                          :D
                                          surreal to think that the basic for the atom was written by Sophie Wilson who went on to design the first arm processor
                                          It's a bit like the pi is having it's great grandparents round to visit
