      @JimmyFromTheBay said in Tesla PMD-85 computer in RetroPie?:

      @Folly The PMD85 booted up in MAME, but the game didn't run when I typed MGLD 00.

      First you have to do the MGLD 00 and then you have to go into the mame menu with the tab key and go to "tape control" and press "play" in order to load the cassette.
      Let me know if it works.

      In the mame menu you can also find the version number.
      Go to "About MAME".
      Please provide them for both standalone mame and lr-mess.
      For lr-mess you can use a system that works in order to get it.

      I have a simple idea to let you run almost the latest lr-mess without interfering with your install.
      Will test my idea first on my computer and let you know if it can work.
      However I need to know what the underlying OS of your RetroPie image is.
      Can you provide the output of this command ? :

      lsb_release -s -i -d -r -c

        @Folly It's Raspbian 10 Buster.

        And the game runs in MAME now, many thanks :)

          Do you want to know the idea to use almost the latest lr-mess without interfering with your setup ?
          Or are you happy with standalone mame ?

              Well, just like with windows it doesn't actually matter where your program is located.
              So here you can find all collected binaries, my builds from source or backups from RetroPie and libretro buildbot.
              So you can just download a binary.
              For instance you should be able to use :
              lr-mess_0.264_arm7l_gcc8_rpi4_probably_missing_drivers_RP_bin.7z
              Then decompress it and place the lr-mess folder in, for example, Downloads, like this :
              /home/pi/Downloads/lr-mess
              That way you don't need root permissions.
              You could rename the lr-mess folder into lr-mess0264 so you will know what version is in the folder, so it becomes :
              /home/pi/Downloads/lr-mess0264
              Then make your own runcommand in the emulators.cfg, for example :

              lr-mess0264-pmd851-cass = "/opt/retropie/emulators/retroarch/bin/retroarch --config /opt/retropie/configs/pmd851/retroarch.cfg --appendconfig /opt/retropie/configs/pmd851/retroarch.cfg.add -S /home/pi/RetroPie/roms/pmd851 -s /home/pi/RetroPie/roms/pmd851 -v -L /home/pi/Downloads/lr-mess0264/mamemess_libretro.so 'pmd851  -rompath /home/pi/RetroPie/BIOS/mame;/home/pi/RetroPie/roms/pmd851/ -cfg_directory /opt/retropie/configs/pmd851/lr-mess -c -ui_active -cass %ROM%'"

              You will see that only the program folder will differ from the "original" runcommand (and for you the core name too).
              For above runcommand the hash folder should not be needed.
              You can keep the hash foler just in there, no need to copy it.

              Well that is the basic idea.
              I tested it here and it did work for me switching between versions.

              Remember, do it for your own risk.
              Don't blame me if somehow something goes wrong.
              Then again, in my opinion there isn't much that can go wrong.

              Let me know if it works for you.

              Btw.
              Newer lr-mess versions lack some drivers.
              Not sure why, but I assume they removed drivers that are not important for the libretro core developers or they just don't have the proper tools to make a full accurate database.
              Anyhow if the pmd851 isn't there you can try an older binary, for example 0251.

                  @Folly Yep, works beautifully, and runs a lot better than MAME too. (Presumably will also work for anything else that needs MAMEMESS.) Many thanks again :)

                    Nice to hear.;-)

                    So now we know it was the old lr-mess version all along.

                    (Presumably will also work for anything else that needs MAMEMESS.)

                    Yep.

                    Btw. 0264 could be the last for Buster and Bullseye.
                    as mame will need newer gcc versions now to compile.
                    But perhaps they make a patch for that, we will see.

                      @Folly So just to figure this out:

                      Let's say I want to be able to run certain MAME games using the new "mamemess" - eg Prize Space Invaders which runs a bit nastily on my old version of lr-mame - but without overwriting the old lr-mame and screwing up all my old systems. I've called it "newmame".

                      So I've added this line to EMULATORS.CFG in the configs/arcade folder:

                      lr-newmame = "/opt/retropie/emulators/retroarch/bin/retroarch -L /home/pi/Downloads/lr-mess264/mamemess_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"

                      All I've done there is take the existing, working line for lr-mame:

                      lr-mame = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame/mamearcade_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"

                      and replace /opt/retropie/libretrocores/lr-mame/mamearcade_libretro.so with /home/pi/Downloads/lr-mess264/mamemess_libretro.so, ie (what looks to me like) replace the old MESS executeable with the new MAMEMESS version.

                      But that crashes (log below), so what have I misunderstood? Do I need to find a different version of MAME and install that in another new folder as I did for the PMD85? I thought the whole point of the "mamemess" thing was that MAME and MESS were the same executeable?

                      Parameters:

                        lr-mamemess.so only runs non-acade.
                        So that is why.

                        Here are my mamearcade.so binaries which are for arcade only :

                        Here is the info of that driver :
                        Driver v4psi (Prize Space Invaders (BWB IN2, £20, 50p/30p Play, 20" Version 1.1) (MPU4 Video)): @casino@misc@no_media@

                        Seems it doesn't have a good tag nor has it a non-arcade or arcade tag.
                        I think the mamearcade.so should have the driver but expect that the driver will not work.

                        Btw.
                        It's better to open a new topic for this as this topic is for PMD-85.

                          @Folly Bah, doesn't work, even though it works in lr-mame with an identical command line except for the address of the executeable :(

                          (What's the difference between, say, the "gcc8" and "gcc10" versions?)

                              @Folly Cheers. I'm puzzled why it doesn't work, then, but it looks like this is the end of the road. Cheers for the assistance with the PMD 85, will be handy with other MESS systems :)

                                Tried this on a PC but pressing Tab does not bring the menu. Tried changing the key bindings but that did not help either. Anyone has an idea?

                                  You tried with "lr-mess" right ?
                                  There have been some changes recently.
                                  You need to use retroarch's "game-focus" (default key is Print-Screen Scroll Lock) first in order to use "tab" for the mame UI.
                                  Let me know if that works for you.

                                    @Folly Actually I used Mame (0.267) - don't really see lr-mess in packages/AUR so I guess this is a Pi-exclusive thing?

                                      lr-mess is not exclusive to the pi only and mame should open up the UI when pressing tab.
                                      You should add more info about your setup and how you installed pdm85.

                                        @Folly understood. my target system is x86_64 pc running arch linux (using Xorg). MAME has been installed via pacman. i downloaded pmd851.zip and a bunch of games in .zip format and placed them into /.mame/roms.

                                        when i run mame, i locate PMD-85.1 entry. when i load it a menu is shown, i am able to Tab into context menu there but not at a later time (when I type MGLD 00 for instance).

                                        i am pretty sure i am making a mistake in my workflow, i just don't know where (have very limited knowledge of MAME).

                                          If you run mame direcly like that you need to add the option -ui_active to the command then you can use the tab key to present the UI.

                                          More info on how to use the command-line options can be found over here.

                                          If you use an arch linux distro you can use ArchyPie instead of RetroPie as RetroPie does not work on an arch linux distro.

                                          My mamedev.sh module-script is adapted to work in ArchyPie.
                                          Only a few parts are missing when running it from ArchyPie.

                                          If you want to discuss this part then go to my topic :

                                            @Folly Thank you, this was extremely useful. This is what I did:

                                            • mame -ui_active
                                            • find PMD-85.1 and load it
                                            • type MGLD 00 inside monitor mode
                                            • Tab -> File Manager -> navigate to auto (198x)(-).ptp -> Return to Previous Menu
                                            • (still in menu) Tape Control - Play
                                            • wait until the game is loaded into machine's memory
                                            • exit menu
                                            • type JUMP 2000
                                            • play the game (Left Shift/V to steer)

                                            Couple observations/questions:

                                            • I am unable to use backspace in monitor mode (does nothing) so there is no room for typos
                                            • did not find a way to speed up tape loading
                                            • multi-game tapes (such as games-1.ptp) are lacking information about the position of the game on the tape - is trial&error the only option?

                                            Thank you again, j
