      @azvarel I can't do more than @acris if it is slow, it is slow 🙂 although I would oike to have all those japanese computers emulators

        low

        Same thing with the RPi3, too slow.

          What I find funny is how A computer from 1987 with a Motorola 68000 CPU 10 MHz, 1MB RAM and no hard drive or of 1993 Motorola 68030 CPU 25 MHz, 4MB RAM and hard drive, do not have an efficient emulation in rpi.

          I had a Classic XBOX which has a 733 MHz x86 Intel Celeron / Pentium III Custom Hybrid rendering and perfectly emulates through the x68000x emulator all the games, the only emulation that was to be desired was CPS3 which for me the rpi3 caters very well.

          Would not be able to make a port of this emulator for the recalbox, since they are both "linux" or am I talking screwed up?

          @voljega, @acris, @Substring is there any basis for this?

            @azvarel depends if ypur emulator had JIT, or DYNAREC, or such code that is cpu dependant and really improves speed

            Former dev - Please reply with @substring so that i am notified when you answer me
            Ex dev - Merci de me répondre en utilisant @substring pour que je sois notifé

              did you try this port https://github.com/libretro/px68k-libretro
              it's not too slow on pi3 ,at least setting 1/2 frame instead Full frame make it pretty usable.

                    @rtype and @azvarel
                    I am not a developer and The team is not available, it is at the HFS convention for 3 days 😄 but
                    I try to compile this core on raspbian

                    mkdir libretro
                    cd libretro
                     sudo git clone https://github.com/libretro/px68k-libretro
                    cd px68k-libretro
                    make -f Makefile.libretro
                    

                    @rtype it's right ? c'est juste ? ou bien il faut des paramètres comment SDL2=1 ou RPI3 ?

                    mkdir /recalbox/share/roms/px68k
                    mkdir /recalbox/share/bios/keropi
                    

                    excecute :

                    killall emulationstation
                    /usr/bin/retroarch -L /usr/lib/libretro/px68k_libretro.so --config /recalbox/share/system/configs/retroarch/retroarchcustom.cfg /recalbox/share/roms/px68k/R-Type.dim
                    

                    I have a red screen 😞 and my keyboard has not F12. lol
                    It's a problem of compilation core.

                    I think it^s

                    make -f Makefile.libretro plateform=rpi3
                    

                    WIP - it' s theory, a developper need to control.

                      il faut des paramètres comment SDL2=1 ou R

                      normalement depuis raspian pas besoin de paramètre.
                      moi je cross-compile depuis mon hôte linux pour compiler plus rapidement (
                      make -f Makefile.libretro plaform=crosspi).

                      Sinon l’émulateur est bien celui de hissorii avec le backport du cpu de yabause issu du fork de kenyahiro. Je ne suis donc pas l'auteur mais j'ai juste fait un portage pour libretro en mixant les 2 .
                      j'ai enlevé toute les références a SDL et X11 dans ce port .
                      Le portage est au stade bêta , donc des erreurs/bugs sont a prévoir.

                      Sinon ce n'est pas une version spécifique ARM , il fonctionne aussi sous linux et windows .

                      A noter cependant qu'il existe une version spécifique pour ARM utilisant le cpu asm ARM cyclone (celui de picodrive)
                      https://github.com/chiorex/px68k/tree/speedup qui doit être plus rapide pour les cpu ARM.

                        j'ai trouvé ton archive sur libretro et testé ton core sur recalbox et ça fonctionne. Mais ma propre compile sur raspbian n'a pas fonctionné. Je recommencerai à l'occasion.
                        Penses tu qu'une version arm serait mieux pour le raspberry ?
                        comment arrives tu à changer la ram alloué au jeu ? j'ai pas réussi.

                          @acris pour la ram il faut booter avec une disquette HumanX style HUMAN302.XDF , et lancer switch.x puis changer la mémoire (4mo est une valeur safe ).

                          https://www.youtube.com/watch?v=XlRQLcqueas

                          pour la version cyclone , je n'ai pas testé.

                            merci je vais voir pour modifier ça semblerait être mieux pour les jeux.
                            tu as essayé en overlockant ton rpi3 pour voir si c'etait mieux au niveau fps ?
                            en tout cas, ta version libretro est meilleur que la version standalone que j'ai testé sous raspbian.

                              Wow, I can not wait to see this working perfectly.

                              @rtype, how would the situation of multi-disc games work? Putting all disks inside a zip file?

                                @azvarel no only 2 floppy are supported you have to swap disk using F12 menu. you can launch a cmd file (text file contening cmd like "px68k /ici/disk1.dim /ici/disk2.dim" and then it will load the 2 disk , but no more than 2.
                                the other way is to load an HDF file (only sasi hdd no scsi hds support)
                                that restriction imposed by actual px68K core

                                  @rtype there is a possibility that instead of doing the cmd files, put the files inside a zip file? and when reading the zip file it identify the amount of floppy disk and load the game?

                                  I know it must be very chaotic programming this way, but much easier when it comes to putting the games to work, without having too much work for those who really want to play.

                                  In relation to F12, is it mandatory for me to have a keyboard, or is there a virtual keyboard?

                                    @azvarel no vkbd for now .
                                    for the zip it not possible as it handle directly from retroarch, i dont know how recalbox works but don't forget it's a libretro core .
                                    edit: for F12 i suppose that it can be bind to a joy button

                                          j ai chargé le human302.xdf j ai tapé switch et j ai eu acces j ai changé mais j ai pas réussi à sortir ou relancer le jeu car c est ça on doit relancer le jeu juste apres ça garde pas en memoire la modification ?
                                          parce que l ideal serait de mettre par défaut à 4096

                                          @azvarel sorry if i speak french but it 's more easy for me to explain my problems.

                                            @acris oui cela garde en mémoire normalement dans le fichier
                                            keropi/sram.dat . (qui se trouve normalement dans libretro system directory)
                                            cela marche en tous cas comme ca avec retroarch. je ne sais pas comment ca marche avec recalbox.
                                            edit: par contre dans switch il faut bien une fois l'option choisie sauvegarder (valider la derniers option tout en bas et taper Y) et après tu peux quitter et relancer .
