      Also to note, if it can help. I have not all versions but see a notable increase of size between 2017 and 2018 :

      OS 170417 Dosbox size 2977700

      OS 180209 Dosbox size 5048136

      OS 180330 Dosbox size 5111180

      For the moment I copied back the version from 170417 to /usr/bin, and again perfect.

          Also something new about the MOUNT C "/usr/share/dosbox" story.
          After copy of dosbox 2017 version, this always exist in the actual OS 180330, seems to be a configuration issue.

            @Dragu @voljega For the moment, not too many notifications ! ๐Ÿ˜‰
            But sorry for the inconveniences.

            The /usr/share/dosbox usage is clearly new to virtual keyboard. The increase of size is strange indeed: new modifications due to b*mp and virtual keyboard modification can't explain this size.

            As voljega said before, can be due to a change in compilation directives !?

            I will check tonight. But, on my RPI2, I detected no lag ... what are your platforms ?

              Dont work in the nights !
              We have time and also a job to pay for the playing toys. ๐Ÿ™‚ Anyway, for the moment, I am fine with older version.
              In my case it is the PI3, but are there differences also in dosbox in PI versions ?
              And dont worry.

                  Could this be a possible explication for the volume size increase, that the 2018 build is the 64-bit version and not the 32 ?

                    Back home ...

                    I've just tested my DosBox RPI2 (updated to 18.03.30) and I confirm: I have no lag problem on games Wolfenstein 3D, Epic Pinball, Ultima 7.
                    The size of my dosbox is 5046488.

                    Can you send a support archive ?

                    Edit: Now, I can reproduce the /usr/share/dosbox bug ! I've never tested without dosbox.bat, in fact.
                    I look for a correction.
                    Still no idea for lags.

                      @Dragu Mine is still 32 bits.
                      Here is the result of the "file dosbox" command, launched from another Linux workstation:
                      dosbox: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 4.4.0, stripped

                        @lmerckx doesn't work in recalbox for me : # file dosbox -sh: file: command not found

                        tried Epic Pinball, lags horribly too :s

                        @lmerckx do you have a RPI3 ?

                          @voljega Yes, I had to transfered my dosbox exec to another Linux workstation to get "file" command.
                          I have a RPI2.

                          Do you also launch games with autoexec or with a dosbox.bat script ?

                            @dragu So, I think I have solved the "/usr/share/dosbox" problem:
                            When there is no dosbox.bat file in directory, DosBox scan other parameters to find a valid file to execute or directory to mount. When it find the share directory, it stops and go on with it.
                            It explains why I had no problem. I always use the dosbox.bat file.

                            So, the solution was to put the initialization of the virtual keyboard before the autoexec startup.

                            But, I'm curious, how do you configure your autoexec ?
                            Do you need to specify the mount and exit in it ?
                            Do you have an example ?

                              s**t I f you don't have a rpi3, it's not gonna be easy to find the issue ...

                              Do you also launch games with autoexec or with a dosbox.bat script ?

                              I always use a dosbox.bat with all necessary instructions in it (mount for instance but no need for exit), I keep no command at all in dosbox.cfg (I always have one too)
                              If you need, I can give you my dosbox.bat and dosbox.cfg for Epic Pinball

                              figured as much, but I don't have any linux at home other than my recalbox ...

                                In general I have always an dosbox.bat file to start games, and mostly the mount operations I make at the end of dosbox.cfg. But this is just personal choice and no issue.
                                I found the story with the VK at testing a game. Because, if you start with dosbox.bat and have an error, you will never see it ๐Ÿ™‚ Screen erase instantly.
                                I for this reason sometimes start a game with no dosbox.bat, for debugging.
                                Concerning the speed lag, it is in relation important 1/2 as before if not less.
                                What is surprising that you have with the PI2 no problems, but we with PI3 have.
                                So, I think solution between both build. ๐Ÿ™‚

                                  I have another idea. Would it be possible to upload somewhere your version of PI2, to test with PI3 ?

                                    @Dragu Good idea. The link is here: https://www.proximuscloud.be/web/app/share/invite/HLQ1C8rABR
                                    If it doesn't work with it ... can you send me your configuration file. Perhaps, is it a change I made which still allow to get good performance.

                                      I think it was not so brillant as idea, as the file is not executable under PI3. I dont know the reason and expected downward compatibility, what is not the case. So, this will unfortunately not help us.
