          If I enter that emulator in the recalbox I simply cry, replay Castlevania and Alice in Wonderland is simply wonderful

          @Substring try to implement this in version 4.1 😄

            Hello

            I tried to compile in raspbian with SDL2

            it's work with gamepad but It's slow.
            emulator use gfx and X11 and theses things are not in recalbox.

            For a developper it will be easy not for me 😛

            • compile with SDL2 without GFX and X11 but with OpenGLESv2
            • Modify keyboard/joystick file

                  @Substring need not be now, but enter the development list

                  I was excited about this 😃

                      low

                      Same thing with the RPi3, too slow.

                        @lolo

                        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

                            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 ).

                                        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?
