      That is interesting.

      I will have a look at that, when I can.

        hope it's useful for someone
        I think your solutions for the electron emulator should only take minor tweaking to get this scripted and working - applying cea-17 at the run command gives a resolution for full screen that just about lets the (f11) gui be seen (at least that is what i'm using)
        sorry about the poor photos - they're only to give you a rough idea of what's possible

          I never had issues, not seeing the (f11) menu.
          I will have try on my tv.

            admittedly I am still using the stretch image so there may be differences as compared with buster - but as far as just playing games?, a little bit of a missing menu is definitely not a deal breaker (for me at least) & I know stretch isn't supported anymore so don't worry too much

              Well, seems a good fix for those who have the same problem !

                Can you tell me, is your speed setting of the good b-em on 100% or is it on 500% ?

                  yes - the 100% option is ticked in the menu
                  The emulator doesn't seem to be too resource hungry - iirc there was only the tiniest amount of slow down when I ran it on my original pi3 - the 3b+ has the occasional sound stutter (start up tune for Arcadians) but everything else seems perfect
                  (I never run overclocks btw - pi speeds are stock)

                    Too bad, we don't know the exact source.
                    Did try to compile that old source of 2012 from http://b-em.bbcmicro.com but could not get it to compile.

                    Btw, I can't extract your .rar file.

                    Did you compile that binary yourself on that "strech" ?

                      try this
                      https://www104.zippyshare.com/v/QoyhNZAp/file.html
                      just need to change permissions on the configure file to executable (probably need to delete the already compiled b-em - or just make executable then run) then ./configure && make - takes ~ 20 mins

                      yes - I've just compiled the zip folder with stretch to test & it works

                      from memory all that was needed dependency wise was
                      sudo apt-get install automake liballegro4-dev zlib1g-dev libalut-dev libopenal-dev aclocal
                      but you should already have that from your electron compiling

                        Just ran it, indeed works perfect here on rpi3 with buster.
                        The menu looks totally different than the latest b-em version 2.2.
                        Your files are from march 2019.

                        Perhaps we can go back to that time on the github page and try to compile that version.
                        For example this one :
                        https://github.com/stardot/b-em/tree/9c586716c6936581b23da4b7b5da365cdf8a47ea

                        Tried it, it works but has the same speed issues as the latest and it looks the same as the latest.

                            No, but indeed we can try.

                              ok - not quite the same version but seems to work
                              need to change permissions of autogen.sh and /utils/b-em-version-str.sh
                              then
                              ./autogen.sh && ./configure && make

                              just tested first level of repton3 - works with no slow down :)

                                I am compiling now.

                                It wasn't working with downloading the source.
                                I now use :

                                git clone https://github.com/SteveFosdick/b-em.git
                                cd b-em
                                ./autogen.sh
                                ./configure
                                make

                                  I think this version is as close as we will get - maybe mine was a few commits earlier
                                  I have the master version of elite running and the cpu is only hitting 30%
                                  Sound may be a little bit more 'glitchy' but not a deal breaker

                                    Cool, it works
                                    I tried some bitshifters-demos.
                                    It works reasonably good but it has some hiccups.
                                    But it seems we are on the right track.;-)
                                    I will look at it again tomorrow.

                                      after much searching and testing I found this version https://github.com/hoglet67/b-em/tree/263d2d44e53e593d1f51c0be9b9f404447fb33a3 to be the best overall (speech in repton3 as good as the beeb got and the arcadians tune as good as my original upload here)
                                      here is the precompiled binary https://www104.zippyshare.com/v/QoyhNZAp/file.html

                                      given the number of forks and commits available, I see no hope of finding the exact files I had

                                      • after a bit more testing i'm starting to think this version is a little better than the one I was originally using

                                      have a play and see what you think is for the best :)

                                        Nice, I will have a look later this day.

                                        The hoglet67 fork if the same as this tree from the original master branch :
                                        ( Edit : tested : quite good :-) )
                                        https://github.com/stardot/b-em/tree/263d2d44e53e593d1f51c0be9b9f404447fb33a3

                                        I think this is a nice starting point.
                                        I think we should take it from the master branch.

                                        I think this is the last one of the latest with allegro4, we should try this one too :
                                        ( Edit : tested : not so good :-( )
                                        https://github.com/stardot/b-em/tree/fc8f15f42f134cb35591587b7aafda9fcebffed8

                                          hi,
                                          just tried the last allegro 4 version and the audio is not right (startup beeps stutter / speech synthesis is off)
                                          good call on taking from the master branch - have a play with the last one I suggested, I think it might just hit the sweet spot for speed and sound

                                            I think so too, had the same experience as you.
