        @barbudreadmon that's something i just don't understand with libretro ports ... Why do they diverge that much from upstream ? Why not work with mains devs for an "easy to keep up-to-date" libretro core as they did with the ppsspp core ?

        Reicast does have armv7 dynarec ...

          Well, that's definitely not on purpose, from what i can tell, arm/x86/x86_64 dynarecs in standalone reicast are really different, i guess the x86_64 one was easy to get working in the libretro port, while the 2 others weren't. Actually, i looked at recent commits and it seems twinaphex is still trying to fix the arm one.

          Libretro developper :

          • FBAlpha FBNeo (Arcade)
          • Kronos (Sega Saturn/ST-V)
          • YabaSanshiro (Sega Saturn)
          • Reicast Flycast (Dreamcast/Naomi/AtomisWave)

            @substring You can find the "standalone version" of reicast-oit there : https://github.com/flyinghead/reicast-emulator
            This one got the dynarec and multithread support, but you still need opengl 4.3 (perhaps it also works with gles3).

              @barbudreadmon yup, found the repo while browding through TA's commits on reicast OIT. Will give it a try after summer unless someone else in the tea wants to have fun with it

                Hi @substring and others.
                The master branch of my reicast fork should work fine on a Pi. I tested it and made sure to keep performance to an acceptable level. It adds a number of features compared to upstream reicast: shadow volumes, clipping, render to texture, multipass rendering support and a number of bug fixes.
                The OIT branch (fh/deferred-shading) on the other hand is very experimental and require desktop-level cpu and gpu (and OpenGL 4.3). It also only works with NVIDIA gpu at the moment and has a couple of bugs, but I intend to improve this in the coming weeks.

                  @flyinghead Hey ! Welcome on board, glad to see you here 🙂

                  how does your reicast fork work compared to skmp's in terms of performance ? like ... does the date finally get saved ? We've also spotted a bug of improper exit of reicast with some dirty die here and there, not cleanly deinit-ing SDL2 which can cause some problems on some boards using GBM rather than FBDEV.

                    Performance should be similar to skmp reicast although most features I added do have a slight performance hit.
                    I also integrated fixes for clean exit, so that the date and VMU are properly saved on exit.

                      @flyinghead That's impressive work !
                      Does Shenmue 2 run on pi3 now ? It's stop after the end of the introduction.
                      It's great to see that there is a hope of seeing improvement with DC emulator on pi 🙂

                          @gaetan I believe the problem with Shenmie 2 is that it has self-modifying code, which breaks the recompiler. I haven’t made any change is this area unfortunately.

                            DC is a great system and it's nice to see people involved in such a project 🙂

                                @flyinghead est-ce que tu sais si sur ton fork les jeux Worms fonctionnent ?
                                Avec la version actuelle il y a un retour à la gamelist systématique quelque soit le format de la rom.

                                  @gaetan Malheureusement, non. Les jeux Worms utilisent Windows CE, qui n'est pas supporté pour le moment.
